1.0 SUMMARY AND CONCLUSIONS
In certain areas of the country where the National Ambient Air Quality
Standard for ozone is being exceeded, additional measurements of ambient
nonmethane organic compounds (NMOC) are needed to assist the affected states
in developing revised ozone control strategies. Because of previous
difficulty in obtaining accurate NMOC measurements, the U.S. Environmental
Protection Agency (EPA) has provided monitoring and analytical assistance to
these states through Radian Corporation. This assistance began in 1984 and
continues through the 1988 NMOC Monitoring Program. Between April 18 and
October 30, 1988, Radian analyzed 3,497 ambient air samples, collected in
SUMMA* polished stainless steel canisters at 45 sites. These NMOC analyses
were performed by the cryogenic preconcentration, direct flame ionization
detection (PDFID) method.1 Based on the 1984, 1985, 1986, and 1987 studies,
the method was shown to be precise, accurate, and cost effective relative to
the capillary column gas chromatographic, flame ionization detection (GC/FID)
method (see Appendix A). The 1988 study confirmed these findings and
supported the conclusion that the PDFID method is the method of .choice to
measure NMOC concentration in ambient air.
In 1986 specific toxic compounds, primarily aromatics and halocarbons,
were also determined in the ambient air samples used for the NMOC analyses.
In 1987 Radian Corporation developed a gas chromatographic multidetector
(GC/MD) method to determine the concentration of 38 selected toxic compounds
in ambient air. In 1988, air toxic analyses were conducted by GC/MD on
ambient air samples taken at 13 sites at which NMOC samples were taken. These
samples were called 3-hour air toxics samples because the sampling period was
3 hours, from 6:00 a.m. to 9:00 a.m. The 1988 Urban Air Toxics Monitoring
Program (UATMP) began in October 1987 at 19 urban sites and extended through
September 1988. The samples from the latter program were 24-hour integrated
ambient air samples and are referred to as UATMP samples throughout this
report.
-------
Volume I of the Final Report includes Sections 1.0 through 10.0.
Sections 1.0 through 6.0 report the data, procedures, and assessment of
the NMOC portion of the monitoring program. Sections 7.0 through 9.0 report
the data, procedures, and assessment of the 3-hour air toxics portion of the
air toxics monitoring program. Section 10.0 lists references for Volume I.
The UATMP data and results will be reported in Volume II.
1.1 NMOC MONITORING PROGRAM
1.1.1 Introduction and Data Summary
Table 1-1 lists the site codes, number of scheduled sampling days, total
scheduled duplicate samples, total scheduled samples, number of valid samples,
and percent completeness. Percent completeness, a quality measure which
ratios the number of valid samples to the number of scheduled samples,
averaged 93.4% in 1988 compared to 95.0% in 1987 and 96.1% in 1986. Percent
completeness ranged from 77.3% for the Chicago, Illinois (C6IL) Chicago
Transit Authority (CTA) site to 101.2% for the Springfield, Massachusetts
(S2MA) Hospital site. The Springfield site surpassed 100% by taking a
duplicate sample on the last sampling date, when no duplicate sample had been
scheduled for S2MA. Statistics for the NMOC concentrations in parts per
million carbon (ppmC) by volume are listed in Table 1-2. In Table 1-2, the
sites are divided tnto "Morning Sites," "Afternoon Sites," and
"Above-300-m-Altitude Sites." The Morning Sites are those which collected
samples from 6:00 a.m. to 9:00 a.m.; Afternoon Sites sampled either from Noon
to 3:00 p.m. or from 1:00 p.m. to 4:00 p.m.; the Above-300-m-Altitude Sites
sampled from 6:00 a.m. to 9:00 a.m. at an altitude above 300 meters.
The sites were separated into these classifications because the average
NMOC concentrations were expected to be different for the three groups. The
overall mean for the Morning Sites was 0.636 ppmC, while for the Afternoon
Sites, the overall mean was 0.353 ppmC. The overall mean for the
Above-300-m-Altitude Sites was 0.286 ppmC.
1.1.2 Calibration and Drift

Reference Material (SRM) No. 1668B propane. Zero readings were determined
with cleaned, dried air. Daily percent drift of the calibration factor ranged
from -10.8% to +6.2%, averaging -0.54 percent. The absolute value of the
percent drift of the daily calibration factors ranged from zero to 10.8%,
averaging 1.07 percent.
1.1.3 Precision
Analytical precision was determined by repeated analyses of 217 site
samples. Percent differences between the second and the first analysis
averaged 0.203 percent. The average of the absolute values of the percent
difference was 10.1% with a standard deviation of 12.4. The analytical
precision includes the variability between Radian channels and within Radian
channels.
Overall precision, including sampling and analysis variability, was
determined by analysis of 265 duplicate site samples, simultaneously collected
in two canisters from a common sampling system. Percent difference for
Radian's analyses of the duplicates averaged 0.31 percent. The average
absolute percent difference was 8.7% with a standard deviation of 10.5.
1.1.4 Accuracy
Because the NNOC measurements encompass a range of mixtures of unknown
compounds, it was not possible to define absolute accuracy. Instead, accuracy
was determined relative to propane standards with internal and external audit
samples.
Accuracy was monitored internally throughout the program by the use of
in-house propane standards. Four days per week an in-house propane quality
control (QC) sample was prepared with a flow dilution apparatus and analyzed
by the PDFID method. The propane used to prepare the in-house QC standards
was certified by the EPA Quality Assurance Division (QAD) and was referenced
to NBS SRM 1668B.
Figures 1-1 through 1-4 show the in-house quality control results for
Radian Channels A, B, C, and D. Measured propane values are plotted against
calculated propane standards. Table 1-3 shows the linear regression
parameters for the Radian in-house quality control data. Daily quality

control samples of prop were mixed from a propane standard certified by
EPA-QAD and referenced to NBS SRM propane Standard No. 1668B. The regression
used the propane concentration calculated from the mixing operation as the
independent variable and concentration measured by each Radian Channel as the
dependent variable. The concentration range of the in-house quality control
samples was 0.0 to 17.775 ppmC. Table 1-3 indicates excellent quality control
for each channel since, as expected, the intercepts are all near zero, and the
slopes and coefficients of correlation are all near 1.0.
External propane audit samples were provided by EPA-QAD. The propane
samples were referenced to NBS SRM propane Standard No. 1668B. Table 1-4
summarizes the percent bias of the Radian channels and the EPA Atmospheric
Sciences Research Laboratory (ASRL) channel relative to the EPA-QAD channel.
The audit samples were given Radian ID Numbers upon receipt. Radian ID
No. 1004 was received in May 1988, and the other two audit samples were
received in September 1988. The average percent bias for the Radian channels
was 2.73%, ranging from 1.33% for Channel B to 4.51% for Channel D. Absolute
percent biases are listed in Table 1-5 and range from 2.32% for Channel B to
4.73% for Channel D, averaging 3.40% overall for the Radian channels.
1.1.5 Other Quality Assurance Measurements
The results of other quality assurance measurements are discussed below.
Canister cleanup studies established that there was little carryover of NMOC
from one sample to the next, when using the canister cleanup apparatus and
procedure developed for this study. In 686 separate determinations, percent
cleanup averaged 99.689%, ranging from 95.3% to 100 percent. Cleanup was
defined in terms of the percent of the NMOC concentration that was removed in
the cleanup cycle. In 1987, the canister cleanup procedure was changed to use
cleaned, dried air that had been humidified instead of cleaned, dried air. It
has been found that humidified air (that had been previously cleaned and
dried) does a better job of removing residual hydrocarbon that had adsorbed on
canister surfaces.
Figure 1-5 shows a between-laboratory comparison of site sample analyses
involving Radian channels and the EPA-QAD channel for the PDFID method.
Figure 1-6 shows comparisons of EPA-ASRL and EPA-QAD channels. Table 1-6
gives the orthogonal regression parameters, assuming a linear relationship,

for Figures 1-5 and 1-6 and other possible comparisons. The results show good
agreement because the intercepts are very close to zero, the slopes are within
12% of 1.0, and the coefficients of correlation are within 3% of 1.0.
For selected hypothetical values of NMOC measured by Radian channels,
EPA-QAD, and EPA-ASRL, Table 1-7 gives the predicted NMOC values for the
remaining channels, based on the orthogonal regression parameters of
Table 1-6. If an NMOC measurement were carried out in one of the three
laboratories, Table 1-7 indicates the expected NMOC concentration and percent
difference to be found if the same sample were analyzed in the other
laboratories. The agreement of the Radian measurements and the EPA-QAD
expected values is excellent. The percent differences among the various
comparisons are very large at ppmC values less than 0.200 ppmC or greater than
5.0 ppmC.
Approximately 10.6% of the NMOC data base was validated by checking data
transcriptions from original data sheets for 54 entries per sample. The six
errors found equal a data base error rate of 0.025 percent.
1.2 THREE-HOUR AIR TOXICS MONITORING PROGRAM
At 13 NMOC sites, 3-hour samples were speciated by a GC/MD analytical
system for 38 UATMP target compounds for a total of 98 NMOC ambient air
samples. After NMOC analysis, the NMOC sample canisters were bled to
atmospheric pressure, stored at least 24 hours for equilibration, and then
analyzed by GC/MD. At 12 of the sites, duplicate samples were collected
simultaneously and analyzed individually by GC/MD. Replicate analyses were
performed on ten of the ambient air samples. A total of 120 GC/MD analyses
were performed, including duplicate samples and replicate analyses.
1.2.1 Overall Data Summary
Twenty-five target compounds were identified in the 120 analyses.
Benzene, m/p-xylene, toluene, ethyl benzene, styrene/o-xylene, and
1,1,1-trichloroethane, in that order, were the most frequently identified
compounds. Concentrations of the target compounds identified ranged from
0.03 ppbv for 1,2-dichloroethane to 57.22 ppbv for chloroform. The overall
average concentration of the target compounds identified was 2.95 ppbv.

1.2.2 Site Results
Overall site mean concentrations ranged from 0.64 ppbv for Braidwood,
Illinois (BRIL), to 5.05 ppbv for Detroit, Michigan (D2MI), for the target
compounds identified. These data are presented in Section 7.0.
1.2.3 Gas Chromatographv/Hass Spectrometrv Confirmation Results
Twenty-four 3-hour air toxics ambient air samples were analyzed by Gas
Chromatography/Mass Spectrometry (GC/MS) for compound identification
confirmation of the GC/MD analyses. The GC/MS analyses were performed after
the GC/MD analyses. The GC/MS analyses confirmed 82.6% .of the GC/MD analyses.
This figure is less than the GC/MS analyses percent confirmation, which was
90.2%, found in the UATMP.
For the 3-hour air toxics samples the negative GC/MD-positive GC/MS
analyses were 15.4%, which was about twice the value found for the same
comparison in the UATMP. Moreover, it was observed that the concentrations
found for most of the compounds identified by GC/MS, but not identified by
GC/MD, was well below 1.0 ppbv and in many cases approaching the GC/MS
detection limits. It was also noted that more than a week's time separated
the GC/MD and the GC/MS analyses.
These facts suggest that many of the compounds found by GC/MS were not
found by GC/MD analyses because at the time of the GC/MD analyses these
compounds were still adsorbed on the canister interior solid surfaces.
The time between the GC/MD analyses and the GC/MS analyses was sufficient to
allow adsorption equilibrium to be more nearly approached. Therefore,
adsorbed compounds could desorb sufficiently to be above the Minimum Detection
Limit (MDL) in the gas phase for the GC/MS analyses.
1.2.4 Precision
Sampling and analytical precision of 3-hour air toxics samples was
estimated by analyzing duplicate samples. In terms of overall average
absolute percent difference, the sampling and analysis precision was
13.7 percent.
can.105 1-20
-------
Analytical precision was estimated by repeated analyses of ten samples.
The analytical precision measured by the overall average absolute percent
difference was 8.5 percent. Both the sampling and analytical precision
results are excellent in view of the concentration range found in this study.
The data analyses showed that both for the duplicate and replicate
results, the imprecision was significantly higher at concentrations less than
2 ppbv. Both the duplicate sample and repeated analyses results are discussed
in Section 8.0.
1.2.5 External Audit
At about the same time the 3-hour air toxics samples were analyzed,
External Audit Sample No. 6 was received from the EPA-QAD. The sample was
analyzed by both the GC/MD and the GC/MS analytical systems. An average bias
of 8.6% was found for the GC/MD analyses and an average bias of -18.4% was
found for the GC/MS analyses. In view of the fact that the GC/MS analyses
were used as a qualitative screening tool for compound identification
confirmation (and not for quantitation), these are excellent results.

2.0 NNOC DATA SUMMARY
This section presents the data summary for the 1988 NMOC Monitoring
Program conducted during April, May, June, July, August, September, and
October. Daily NMOC concentrations and other pertinent monitoring data are
given by site in Appendix E. The majority of the data presented in this
section summarize the NMOC concentrations measured for samples collected at
45 sites throughout the continental United States, Sites were selected in
urban and/or industrial locations; they are described in Appendix D. The site
codes for the 1988 NMOC Monitoring Program are listed in Appendix D and are
used throughout the report to identify the sites. Samples were collected in
6-liter (L) stainless steel canisters by local site operators trained by
Radian Corporation personnel. The sampling procedure was described in
detailed written instructions and given to the site operators. The sampling
procedure instructions also appear in Section 3.1.2. Analytical concentration
measurements of NMOC were made in the Radian Corporation Research Triangle
Park (North Carolina) laboratory according to the PDFID method developed by
the U.S. EPA and given in Appendix A.
The concentration of oxides of nitrogen (NO ), site temperature,
barometric pressure, wind direction., and weather conditions were provided on
the field sampling forms by site personnel at the time of sampling. These
data were recorded in the 1988 NMOC data base, but are not presented in this
report because they were not measured by Radian equipment or personnel, nor
were the data subjected to Radian quality assurance procedures.
Table 2-1 lists the NMOC Monitoring Program completeness results by site
code. The scheduling of sample days and the scheduling of duplicate analyses
is given in the Quality Assurance Project Plan (QAPP). Two sites, M2TN
(Memphis, Tennessee, Frayser Street Site) and S2MA (Springfield,
Massachusetts, Hospital Site), produced over 100% completeness by taking an
unscheduled duplicate in addition to all other scheduled samples. The C6IL
(Chicago, Illinois, CTA Site) posted a 77.33 percent completeness, because

of an unstable local situation out of Radian's control. For the remainder of
the 1988 NMOC sites, completeness was over 80%, and generally very near to 100
percent. A complete listing of invalid samples and the reasons for the
invalidation are given in Appendix F.
Completeness figures for the 1988 NMOC Program show 93.4% complete. This
compares with 95.0% complete in 1987, 96.8% complete in 1986, 95.8% complete
in 1985 and 90.6% complete in 1984. ' * ' Completeness was defined as the
percentage of samples, scheduled in the QAPP, that were collected and
analyzed as valid samples, beginning with the first valid sample and ending
with the last valid sample.
Table 2-2 summarizes statistics by sites into three classifications,
Morning Sites, Afternoon Sites, and Above-300-m-Altitude sites. "Morning
Sites" were those where an integrated samples was collected from 6:00 a.m. to
9:00 a.m. "Afternoon Sites" collected samples either from Noon to 3:00 p.m.
or from 1:00 p.m. to 4:00 p.m. The "Above 300-m-Altitude Sites" collected
ambient air samples from 6:00 a.m. to 9:00 a.m. at altitudes above 300 meters
from ground level. Morning and Afternoon Site samples were collected at about
10 meters above ground level. The subclassifications of the NMOC Monitoring
Sites were made because it was hypothesized that the mean NMOC values would be
different in the Morning and Afternoons Sites, or at the higher altitude.
The overall average of the Morning Site NMOC concentration is seen to be
0.636 ppmC, while the Afternoon Site NMOC concentration average is 0.353 ppmC,
about 56% of the morning concentration average. The higher altitude sites,
although only two in number, average 0.286 ppmC, only 45% of the morning
concentration average.
The overall (arithmetic) mean NMOC concentration for 1988 was 0.636 ppmC,
0.738 in 1987, 0.776 in 1986, 0.755 in 1985, and 0.853 in 1984. The overall
NMOC statistics given here and elsewhere are generally reported for the NMOC
samples taken from 6:00 a.m. to 9:00 a.m., unless otherwise indicated.
In Table 2-2, the means are the arithmetic averages of the NMOC
concentrations at each site. The numbers given for standard deviation,
skewness, and kurtosis are the second, third, and fourth moments, respectively

about the arithmetic means. A skewness value greater than zero applies to
distributions having a longer tail to the right. A distribution that is
normally distributed would have a kurtosis of 3.0. A distribution more peaked
(or pointed) than a normal distribution, having the same variance, would have
a kurtosis greater than 3.0.
NMOC data for 1988 can be better characterized by a lognormal
distribution than by a normal distribution, following the 1987, 1986, and 1985
findings.2'3'4 Table 2-3 summarizes the 1988 NMOC data using the definitions
that characterize a lognormal distribution, overall, and for each site. MU
and SIGMA are the mean and standard deviation, respectively, of the logarithm
of NMOC to the Napierian base e. The geometric mean is e raised to the power
MU; the geometric standard deviation is e raised to the power SIGMA. The mode
is the most frequently occurring logarithm of NMOC value for a continuous
probability distribution function.
Information listed in Appendix D includes the location of the site,
street address as well as the Universal Transverse Mercator (UTM) coordinates
for the site (where available), the site code used throughout this report, the
Storage and Retrieval of Aerometric Data (SAROAD) Number, and the Aerometric
Information Retrieval System (AIRS) Number. In addition, the general
classification of the site location, such as "Urban Industrial" or "Urban
Residential," is listed. Elevation above sea level and other pertinent
information about each site are listed where available.
Appendix E gives the daily NMOC concentration data listed chronologically
for the entire sampling season. In addition, figures are given for each site
in which NMOC concentrations in ppmC are plotted versus the 1988 Julian date
on which the sample was taken. Data tables for each site include the

3.0 NHOC TECHNICAL NOTES
This section includes a summary of the installation and operation of the
field sampling equipment, a summary of the analytical equipment and procedures
for NMOC measurement, and a description of the canister cleanup equipment and
procedures.
3.1 NMOC FIELD SAMPLING EQUIPMENT
The field sampling equipment used in the collection of ambient air
samples for NMOC measurement is relatively simple to operate. Ambient air is
drawn through a sintered stainless steel filter (2 micron) and critical
orifice by a Metal Bellows* pump and delivered to a SUMMA* canister. The
sampler components are made of nonbiasing stainless steel. Figure 3-1 shows a
schematic diagram of the NMOC sampling system.
3.1.1 Installation
NMOC sampler installation configurations were site dependent. All field
sites were installed by or under the direction of Radian personnel.
Installation requirements included a temperature controlled environment (70°
to 86°F), close proximity to the atmosphere to be sampled, and
noncontaminating sampler connections. Glass and/or gas-chromatographic-grade
stainless steel tubing are the preferred materials of construction for all
connections contacting the sample. Typical sampler installations involved
three configurations dependent on site constraints. These installation
configurations included direct connections to a ventilated glass manifold, a
slipstream connection prior to the station NO analyzer with a bypass pump, or
collocated NMOC and NO sample inlet lines. For sites where the distance
A
between the sample inlet and the stainless steel post was greater than 8 feet,
an auxiliary pump, as shown in Figure 3-1, was used. The auxiliary pump helps
insure that the air in the sample line is representative of the ambient air.
The critical orifice was sized to maintain a constant flow rate and to fill a
6-L stainless steel canister from the 5 mm Hg vacuum to about 15 psig in
3 hours. When duplicate samples were taken the critical orifice used for

single sample collection was replaced with an orifice sized to fill two
canisters during the 3-hour sampling period.
3.1.2 Operation
Presamplinq
The following instructions pertain to the sampling operation prior to
collection of the field sample.
1.0 Verify timer program (see timer instructions). Set to MANUAL
position to leak check sampling system. Once the system passes the
leak check, turn timer to AUTO position.
2.0 With no canisters connected to the sampling system, turn the timer
switch to the MANUAL position.
3.0 Disconnect the sample inlet from the top of the orifice/filter
assembly mounted on the pump inlet. Connect the rotameter to the
top of the orifice/filter assembly. Tighten Swagelok* (1/4")
fitting securely with a wrench. Do not overtighten.
4.0 Turn timer switch ON. Do not turn the power off and on rapidly.
Wait 20 seconds .between cycles to prevent premature timer/solenoid
failure. The pump should run and the latching valve should open
(audible click with 2 to 5 seconds delay). Verify that the
rotameter reading is approximately the same (+15%) as the reading
obtained during installation as recommended on the orifice tag. If
the rotameter reading is not correct, see the troubleshooting
instructions.
5.0 Allow the pump to run for at least 20 seconds, then press the timer
OFF button.
6.0 Connect a cleaned, evacuated canister to the sampling system. If •
duplicate samples are to be collected, remove the plug from the
second port of the tee and connect a second canister to the sampling
system. Remove the orifice assembly marked with an "S," denoting a
single orifice. Install the orifice assembly marked with a "D,"
denoting a double orifice. Replace the filter holder on the "D"
orifice. After obtaining scheduled duplicate samples, replace the
plug and the "S" orifice assembly to return to single sample
collection status.
7.0 With the pump off, open completely the valve on the canister (or on
one of the canisters if two are connected) and verify that no flow
is registered on the rotameter. If any flow is detected by the
rotameter, immediately close the canister valve and see the
troubleshooting instructions.
cah.lll 3-3
-------
8.0 If no flow is observed, disconnect the rotameter and reconnect the
inlet sample line to the filter assembly. If two canisters are
connected, completely open the valve on the second canister.
9.0 Reverify that the canister valve(s) is (are) completely open and the
timer is properly set for sampling from 6 a.m. to 9 a.m. the next
weekday. Set timer to AUTO mode.
10.0 Reset the elapsed time counter.
Postsampling
The instructions that follow outline the NMOC postsampling operation
procedures in the field.
1.0 Close the canister valve(s) firmly. Disconnect the canister(s) from
the sampling system.
2.0 Connect the pressure gauge to the canister inlet and open the
canister valve. Record the canister pressure on the field sampling
data form. Close the canister valve and remove the pressure gauge.
Repeat pressure measurement for second canister if collecting a
duplicate sample. If the pressure reading is not at least 11 psig,
see the troubleshooting instructions.
3.0 Fill in the required information on the NMOC SAMPLING FIELD DATA
FORM. The form is a multiple page carbonless form. PLEASE PRESS
HARD WITH A BALLPOINT PEN (see Figure 3-2).
4.0 Verify elapsed time counter reading equals 3 hours.
5.0 Verify that the timer shows the correct time setting. If not, note
that fact on the sample form along with any information pertaining
to the possible cause. Reset the timer to the correct time, if
necessary.
6.0 Verify that the canister valves are closed firmly. Do not
overtighten them. Put the protective cap(s) on the valve(s) and
prepare the canister(s) for shipment to Radian, RTF.
3.1.3 Troubleshooting Instructions
A list of troubleshooting instructions was given to each field site
during the site installation and operator training. Typical problems
encountered with the field sampling apparatus included: loose fittings,
misprogrammed timer, or clogged orifice. To minimize downtime, field site

operators were encouraged to relay sampling problems to the Radian laboratory,
daily, by telephone. Most sampling problems were addressed through these
telephone discussions.
3.1.4 Sampler Performance for 1988
The NMOC sampler was modified in 1988 in order to improve performance.
This modification involved replacing the mechanical timer previously used with
an electronic version. The electronic timer improves sample integration. An
elapsed time counter was added to the sampler to verify sample duration. In
addition, all sampler orifice(s) and canisters were subjected to a preseason
QC check to ensure field performance. All orifices were checked against the
rotameter enclosed in each sampling kit, and referenced to a transfer standard
(bubble flowmeter). Prior to field installation, all samplers were operated
in the laboratory to establish an expected final pressure range for the
canister samples. Two single orifices and one double orifice were tested for
each sampler kit.
Due to the preseason checks and modifications, the NMOC sampler
performance was improved for the 1988 sampling season. This assessment is
based on the consistency of the final sample pressures on a site-specific
basis (see Section 4.6). The sampler performance in terms of successful
sample collection (i.e., completeness) was comparable to previous years.
Overall completeness from all sites averaged 93.4 percent. The site-specific
completeness ranged from 77.3% for C6IL to 101.2% for S2MA.
A listing of invalidated or missing samples is contained, chronologically
and by site, in Appendix F. Invalidated or missing samples were primarily due
to the operator or the site rather than to equipment. Completeness can be
improved at certain sites through greater attention to sampling procedure, and
by ensuring that trained site personnel are available. Those samples that
were invalidated due to equipment failure were assigned to three major
categories: timer, canister, and miscellaneous.
A total of 230 missing or invalidated samples were recorded in the 1988
NMOC Monitoring Program. There were 52 invalidated samples related to timer
problems, 71 invalidated samples related to canister problems, and 103
remaining invalidated samples. Avoidable operator error accounts for 82.7% of
cah.lll 3-6
-------
the timer-related invalidated samples, while 17.3% were attributable to timer
malfunctions. The operator's failure to open the canister valve accounted for
38.0% of the canister-related invalidated samples, and 40.9% were attributable
to canister leaks. Of the remaining 103 invalidated samples, 49.5% were
caused by loose or broken sample lines, or leaking solenoid valves; 51.5% were
attributable to missed samples, power outages, or consecutive samples
collected into the same canister.
A further improvement in completeness may be possible as site operators
gain familiarity with the electronic timer. Revised sampler operating
instructions will focus additional attention on timer programming and
operation, and will include a daily checklist to eliminate common operator
errors.
3.1.5 Field Documentation
The field sample collection information was documented by the site
operator on preformatted forms. Figure 3-2 is an example NMOC Sampling Field
Data Form. Each canister sent to the field was accompanied with this form.
The field data form is a multiple part unit. A copy of the field data form
was retained by the site operator for the site notebook. Figure 3-3 is the
Invalid Sample Form. This form was completed by the site operator to document
the reasons for a missed or invalid field sample collection episode.
3.2 NMOC ANALYSIS
The NMOC analysis equipment and analysis procedure are described in
greater detail in Appendix A. A brief description of the equipment and
operating procedure used in this study follows.
3.2.1 Instrumentation
Two gas chromatographs were used by Radian. Each was a dual-channel
Hewlett-Packard Model 5880 (HP-5880) using flame ionization detection (FID).
NMOC instrument Channels A and B refer to the two FIDs on one HP-5880 unit,
and Channels C and D refer to the two FIDs on the other HP-5880 unit. These
chromatographs were modified to be similar to the prototype unit (EPA-QAD
instrument), which is described in Appendix A. The EPA-QAD instrument was
used as a reference during this program. In addition, an HP-5880 gas
chromatograph located at EPA and equipped with a 60 m x 0.32 mm i.d., DB-1,

3.2.2 Hewlett-Packard. Model 5880. Gas Chromatooraph Operating Conditions
The sample trap consisted of 30 cm of 1/8-inch outside diameter (o.d.)
stainless steel tubing, packed with 60/80 mesh glass beads.
Three support gases were used in this analysis: helium, hydrogen, and
hydrocarbon-free air. Details of their use are given below in Table 3-1.

The operating temperatures of the HP-5880 were controlled for the NMOC
analysis. The FID and auxiliary area were controlled at 250°C and 90°C,
respectively. The oven temperature was programmed from 30°C to 90°C at a rate
of 30°C per minute for 4 minutes, holding at 90°C for the fourth minute. Oven
and integration parameters were controlled by HP Level 4 programmable
integrators. A complete listing of the integrator programming sequence for
NMOC measurement by the PDFID method is given in Appendix C.
3.2.3 NMOC Analytical Technique
The modified HP-5880, dual-FID chromatographs were operated during the
1988 study according to the Standard Operating Procedure (SOP) listed in the
QAPP. Further description is given below to help explain the analytical
apparatus and procedure.
cah.lll 3-9
-------
The six-port valve shown in Figure 3-4 was installed in the auxiliary
heated zone of the HP-5880 and was pneumatically actuated using
chromatographic valve control signals to apply either compressed air or vacuum
to the valve. The sample trap itself was located inside the chromatograph's
column oven. A section of 1/16-inch o.d. stainless steel tubing was sized to
a length that prevented pressure and flow surges from extinguishing the FID
flame. This length was determined experimentally and differs for each
chromatograph and for each channel within chromatographs. Although the length
of tubing effectively substitutes for the pressure restriction provided by a
column, it does not perform its separation function.
During sample trapping, a slight excess of sample gas flow was main-
tained. A pressure change of 80 mm Hg in a 1.7-L vacuum reservoir was used to
gauge and control the volume of sample gas cryogenically trapped. After the
trapping cycle was complete, the HP-5880 program shown in Appendix B was
initiated. When the program triggered a horn emitting an audible beep, the
cryogen was removed from the trap and the oven door was closed. The
chromatographic program then assumed control of raising the oven temperature,
at the preset rate, to release the trapped sample to the FID, and set up the
integration parameters.
3.3 CANISTER CLEANUP SYSTEM
A cleanup cycle consisted of first pulling a vacuum of 5 mm Hg absolute
pressure in the canister, followed by pressurizing the canister to 20 psig
with cleaned, dried air that-had been humidified. This cycle was repeated two
times during the canister cleanup procedure. The cleanness of the canister
was qualified by PDFID analysis. Upon meeting the cleanness criterion, the
canister was evacuated to 5 mm Hg absolute pressure a third time, in
preparation for shipment to the site.
3.3.1 Canister Cleanup Equipment
A canister cleanup system was developed and used to prepare sample
canisters for reuse after analysis. A diagram of the system is shown in
Figure 3-5. An oil-free compressor with a twelve-gallon reservoir provided
source air for the system. The oil-free compressor was chosen to minimize
hydrocarbon contamination. The compressor reservoir was drained of condensed

removed water vapor from the compressor source air. These permeation dryers
were followed by moisture indicators to show detectable moisture in the air
leaving the dryer. The moisture indicators never showed any water, indicating
that the permeation dryers effectively removed all of the water vapor.
Air was then passed through catalytic oxidizers to destroy residual
hydrocarbons. The oxidizers were followed by inline filters for secondary
particulate matter removal, and by a cryogenic trap to condense any water
formed in the catalytic oxidizers and any organic compound not destroyed by
the catalytic oxidizer. A single-stage regulator controlled the final air
pressure in the canisters and a metering valve was used to control the flow
rate at which the canisters were filled during the cleanup cycle. The flow
was indicated with a rotameter installed in the clean, dried air line. There
was a shutoff valve between the rotameters and the humidifier system. The
humidifier system consisted of a SUMMA* treated 6-L canister partially filled
with high performance liquid chromatographic-grade (HPLC-grade) water. One
flowmeter and flow control valve routed the cleaned, dried air into the 6-L
canister where it was bubbled through the HPLC-grade water. A second
flow-control valve and flowmeter allowed air to bypass the canister/bubbler.
By setting the flow-control valves separately, the downstream relative
humidity was regulated. For the 1988 study, Radian used two relative humidity
settings. Until July 1988, 20% relative humidity was used. After July, 80%
relative humidity was used for canister cleaning. There was another shutoff
valve between the humidifier and the 8-port manifold where the canisters were
connected for cleanup.
The vacuum system consisted of a Precision Model 00-310 vacuum pump, a
cryogenic trap, an absolute pressure gauge, and a bellows valve connected as
shown in Figure 3-5. The cryogenic trap prevented the sample canisters from
being contaminated by back diffusion of hydrocarbons from the vacuum pump into
the cleanup system. There are no oil-free high vacuum pumps currently
available. The bellows valves enabled isolation of the vacuum pump from the
system without shutting off the vacuum pump.

-------
3.3.2 Canister Cleanup Procedures
After NMOC analyses were completed, a bank of eight canisters was
connected to each manifold shown in Figure 3-5. The valve on each canister
was opened, with the shutoff valves and the bellows valves closed. The vacuum
pump was started and one of the bellows valves was opened, drawing a vacuum on
the canisters connected to the corresponding manifold. After reaching 5 mm Hg
absolute pressure as indicated by the absolute pressure gauge, the vacuum was
maintained for 15 minutes on the eight canisters connected to the manifold.
The bellows valve was then closed and the cleaned, dried air that had been
humidified was introduced into the evacuated canisters until the pressure
reached 20 psig. The canisters were filled from the clean air system at the
rate of 7.0 L/min. This flow rate was recommended by the manufacturer as the
highest flow rate at which the catalytic oxidizers could handle elimination of
hydrocarbons with a minimum 99.7% efficiency.
When the first manifold had completed the evacuation phase and was being
pressurized, the second manifold was then subjected to vacuum by opening its
bellows valve. After 15 minutes, the second manifold was isolated from the
vacuum and connected to the clean, dried air that had been humidified. The
first manifold of canisters was then taken through a second cycle of
evacuation and pressurization. Each manifold bank of eight canisters was
subjected to two cleanup cycles.
During the second cleanup cycle, the canisters were pressurized to
20 psig with clean, dried air that had been humidified. For each bank of
eight canisters, the canister having the highest precleanup NMOC concentration
was selected for NMOC analysis to determine potential hydrocarbon residues.
If the analysis measured less than 0.030 ppmC, then the eight canisters on the
manifold were considered to be clean. Finally the canisters were again
evacuated to 5 mm Hg pressure absolute; they were capped under vacuum and then
packed in the containers used for shipping to the field sites.

4.0 NMOC QUALITY ASSURANCE/QUALITY CONTROL PROCEDURES
This section details the steps taken in the 1988 NMOC Monitoring Program
to ensure that the data taken were of known quality and were well documented.
Analysis results are given in terms of precision, completeness, and accuracy.
Repeated analyses provided analytical precision. Duplicate samples provided
sampling and analysis precision. Completeness was measured in terms of
percent of scheduled samples that resulted in valid samples, beginning with
the first valid site-specific sample collected and ending with the last valid
site-specific sample collected. Accuracy of NMOC concentrations was reported
as percent bias of audit samples referenced to an NBS SRM propane by EPA-QAD.
4.1 INTRODUCTION AND CONCLUSIONS
Completeness for the 1988 NMOC study was 93.4 percent. This value
compares to 95.0% completeness for the 1987 study, 96.8% for the 1986 study,
and 95.8% for the 1985 study, and indicates that good communication and
planning were maintained between the site personnel and the laboratory
personnel. Precision for the 1988 NMOC study averaged 10.06% absolute percent
difference of repeated analysis and compared to 9.61% for the 1987 study,
*9.01% for the 1986 study, and 10% for the 1985 study. Bias of the Radian
channels for the 1988 audit results ranged from +1.3% to +4.5 percent. In
1987 the accuracy determined from the external audit samples ranged from -2.9%
to -0.06 percent. In 1986 bias ranged from -0.52% to -3.3% and in 1985 bias
ranged from -2.3% to +5.2 percent.
An initial multipoint performance evaluation was done with propane
responses for each Radian channel. Twice daily calibration"checks and daily
in-house propane QC samples monitored instrument and operator performance.
Duplicate site samples showed good overall sampling and analysis precision as
well as sample stability.
Data validation was performed on 10.6% of the 1988 NMOC data base, as
described later in this section.
-------
Precision and accuracy results for 1988 are comparable to results from
previous years and indicate that the data quality are good and meet all of the
data quality objectives of the Quality Assurance Project Plan (QAPP).
Completeness for 1988 was slightly below that of 1987. But because of local
conditions, especially at Chicago and New York, it was not possible to
maintain the completeness measure above 95 percent.
Calibration and drift determinations showed that the instrumentation was
stable and that the calibration procedures were consistent. Canister cleanup
results showed there was negligible carryover from one sample to the next.
In-house QC samples of propane demonstrated that the analytical systems were
in control.
4.2 CALIBRATION AND INSTRUMENT PERFORMANCE
Initial performance assessments for NMOC were conducted with propane.
Daily calibrations were checked with about 3.0 ppmC propane for the NMOC
measurements.
4.2.1 Performance Assessment
An initial performance assessment was done on each Radian channel, using
propane certified by EPA-QAD. EPA-QAD referenced the certified propane to an
NBS SRM No. 1668B propane. The concentration of the propane used in the
performance assessment ranged from 0.000 to 17.775 ppmC. The "zero" value was
determined using cleaned, dried air from the canister cleanup system described
in Section 3.0. Table 4-1 summarizes the performance assessments below. The
responses are linear, having coefficients of correlation from 0.999747 to
0.999972. Figures 4-1 through 4-4 show plots of the NMOC performance results
for Radian Channels A, B, C, and D, respectively. The plots show the regres-
sion line.
4.2.2 Calibration Zero. Span, and Drift
Radian PDFID channels were tested twice daily for zero and span. Zero
readings were measured using cleaned, dried air. The zero air was supplied by
the same system that cleans air for the canister cleanup system. Span
readings used a mixture of about 3.0 ppmC propane-in-dry-air. Calibration
factors were calculated from the span and zero readings for each Radian

channel. Initial calibration factors were determined in the morning before
any site samples were analyzed and final calibration factors were determined
in the afternoon after all the ambient air samples had been analyzed. Percent
calibration factor drifts were determined based on the initial calibration
factor. The data for zeros, calibration factors, and calibration factor
drifts are given in Appendix G for each Radian channel and each calendar day
of the analysis season. Figures 4-5 through 4-8 show plots for daily
calibration zeros for Radian Channels A, B, C, and D. Figures 4-9 through
4-12 show the daily calibration span data as a function of the 1988 Julian
date. Figures 4-13 through 4-16 show daily percent drift figures for the 1988
Julian dates. Inspection of the percent drift figures shows that all of the
Radian channels drifted less than 12%, which indicates that the analytical
systems were in control and produced excellent results.
4.2.3 Calibration Drift
Summary calibration factor drift data are given in Table 4-2. The table
presents calibration factor drift, percent calibration factor drift, and
absolute percent calibration factor drift. Calibration factors were
calculated from an analysis of a propane-air mixture whose concentration was
known and was referenced by the EPA-QAD to an NBS SRM No. 1668B propane
reference standard as follows:
calibration = concentration of propane standard fppm) x 3 ppmC/ppm
factor (propane standard response (area counts) - zero response
(area counts))
Daily calibration factors ranged from 0.000293 ppmC/area count to
0.000334 ppmC/area count, depending on the channel. Maxima, minima, and mean
values are given in Table 4-2 for calibration factor drift and percent
calibration factor drift.. If drift and percent drift are random variables and
normally distributed, the mean values would be expected to be zero. The means
shown in Table 4-2 for the drift and percent drift are approximately zero,
showing little bias overall, or for any channel. The overall mean values
shown in Table 4-2 were weighted according to the number of calibration drift
data for each channel. The last two columns of Table 4-2 show the means and

standard deviations of the absolute percent calibration factor drifts. The
fact that the standard deviations are the same order of magnitude as the means
indicates that the mean calibration factor drifts are not significantly
different from zero.
Calibration factor drift was defined as final calibration factor minus
initial calibration factor. Percent calibration factor drift was defined as
the calibration factor drift divided by the initial calibration factor,
expressed as a percentage. The absolute percent calibration factor drift is a
measure of the calibration drift variability and averaged 1.07% overall. The
mean absolute percent calibration drift ranged from 0.78% for Radian Channel B
to 1.38% for Radian Channel D.
4.3 IN-HOUSE QC SAMPLES
In-house quality control samples were prepared daily except for one day
during the week on which duplicate local ambient samples were collected for
"Round-Robin" analyses. The local ambient samples were analyzed not only by
all Radian PDFID channels, but by EPA-QAD and EPA-ASRL instruments. Local
ambient sample results are presented and discussed in Section 4.4.4. In-house
quality control samples were prepared by diluting dry propane with cleaned,
dried air using calibrated flowmeters. The propane used for the in-house
quality control samples was certified by the EPA-QAD against an NBS Reference
Standard. The concentration of the in-house standard varied from about
0.020 ppmC to 18.000 ppmC, but was set to average near the concentration
levels that were being analyzed (0.100 to 3.000 ppmC). The analyst did not
know the concentration of the in-house standard prior to analysis.
The daily in-house QC data for each Radian channel are given in
Appendix H, and include:
• Calendar date analyzed;
• Julian date for 1988;
t Radian ID Number;
• Calculated NMOC concentration in ppmC;
• Measured NMOC concentration in ppmC;
• Bias (measured NMOC-calculated NMOC); and
• % Bias (Bias * 100 / calculated NMOC).

-------
Measured versus calculated NMOC concentrations in Figures 4-17 through
4-20 show excellent agreement. Table 4-3 summarizes the results of the linear
regressions for the Radian in-house quality control data, showing regression
intercepts near zero, and slopes and coefficients of correlation all near 1.0.
Tables 4-4 and 4-5 give statistics for in-house quality control measure-
ments. DIFF is the ppmC difference between the measured and the calculated
NMOC concentrations, and PCDIFF is the percentage of the difference relative
to the calculated value. Both DIFF and PCDIFF may be considered to be bias
terms, assuming that the calculated value is the correct NMOC concentration
for the in-house QC sample. Overall, PCDIFF shows a mean bias of +1.46%, and
ranges from +0.81% for Channel D to +1.90% for Channel B. ADIFF and APCDIFF,
absolute values of DIFF and PCDIFF, respectively, were used as measures of
precision. The absolute percent difference ranged from 3.05% for Channel C to
3.47% for Channel D and averaged 3.30 percent. These figures show excellent
agreement and consistency for the in-house quality control data and include
errors, not only in the instrumental analysis but also in the apparatus and
method used to generate the QC samples.
Figure 4-21 shows a stem-and-leaf plot of DIFF, the NMOC difference
between the calculated and measured in-house quality control samples. The
figure shows some negative skewness, but also shows the differences to be
approximately normally distributed, which supports the assertion that DIFF is
a random variable. The normal distribution of DIFF also implies that there is-
no significant bias between instrument channels.
4.4 REPEATED ANALYSES
Two types of repeated analyses were conducted in this study. The first
type of repeated analysis was conducted primarily to establish precision, and
to determine if significant differences in precision existed among Radian
(PDFID) channels, the EPA-QAD (PDFID) channel, and the EPA-ASRL (GC/FID)
channel. Two samples daily were selected from the received site samples for a
second analysis on a Radian channel on the following workday. The second
replicate analysis was performed on the day after the first analysis to allow
time for the ambient air sample in the canister to equilibrate between
analyses. At the beginning of the first analysis, the pressure in the

canister is typically about 15 psig. At the beginning of the second analysis,
the canister pressure is typically 9 psig. The pressure difference between
the two analyses may be sufficient to affect the organic compound adsorption
(or absorption) equilibrium between the organic compounds in the gas phase and
those in the sorbed phase.
The QAPP specified which Radian channels were selected for the repeated
analyses, so that all combinations of channel pairs, i.e., A-A, B-B, B-C, A-D,
etc., would be selected randomly. The EPA-QAD and the EPA-ASRL channels
randomly repeated analyses of the site samples already analyzed once by
Radian. None of the site samples selected for repeated analyses by Radian
•channels was analyzed a third time by an EPA channel.
Beginning about July 15, the QAPP was changed so that the two samples
selected for the replicate analyses were also duplicate samples. By
conducting repeated analyses of the duplicate samples it was possible to
investigate the relative magnitude of the duplicate sampling precision and the
analytical precision. The results for this investigation are given in
Section 4.5.3.
The second type of comparative analysis was done on local ambient samples
collected by EPA-QAD personnel in Raleigh, in Research Triangle Park, or near
Research Triangle Park, North Carolina. These samples were taken once weekly
in duplicate at an initial pressure of about 35 psig. Each local ambient
sample, called a round-robin sample, was analyzed by all four Radian channels,
the EPA-QAD channel, and the EPA-ASRL channel. One of the duplicate
round-robin samples was analyzed first in the Radian laboratory while the
other duplicate round-robin sample was analyzed first in the EPA laboratories.
Upon completion of the analyses, the laboratories exchanged canisters and
analyzed the other duplicate sample on all channels. The purposes of these
studies were:
t to determine if the order of analysis by one laboratory or
channel made a significant difference in the measured NMOC
value;
t to compare the precision of all the channels;
• to compare the PDFID method of analysis with the GC/FID
speciated method of analysis; and
t to compare the results among Radian channels.

4.4.1 Site Sample Results
Figure 4-22 compares the EPA-QAD analyses with Radian analyses of the
same site samples. Figure 4-23 compares the EPA-ASRL analyses with Radian
analyses. Figure 4-24 compares ASRL analyses with QAD analyses. Orthogonal
regression parameters for the three data sets are summarized in Table 4-6.
Summary statistics of the comparative analyses for Radian channels versus
the EPA-QAD channel are given in Table 4-7. The table gives DELTA, the
difference between the Radian NMOC concentration and the QAD NMOC
concentration in ppmC; and PDELTA, the percent difference relative to the mean
of the Radian and QAD analyses. ADELTA and APDELTA are the absolute values of
DELTA and PDELTA, respectively. The mean percent difference shows Radian NMOC
concentrations to average 1.64% lower than the QAD NMOC concentration. This
is an average bias figure for the Radian analyses relative to a mean NMOC
concentration. The average absolute percent difference is 11.76, which is a
measure of the precision.
In 1987, the mean percent differences showed Radian concentrations to
average 4.48% lower than the QAD NMOC concentration. The average absolute
percent difference was 14.07%, relative to the mean of the Radian and QAD NMOC
concentrations. The agreement between the 1987 and 1988 precision results is
good, and shows that the instruments and operating procedures were consistent
for the two years.
Summary statistics are given for the same data in Table 4-8 by Radian
channel. The data show a mean absolute percent difference ranging from
9.34 for Channel A to 15.89 for Channel B. The mean percent differences range
from -7.27% for Channel B to +4.55% for Channel D.
Table 4-9 summarizes statistics for comparative analyses for Radian
channels versus ASRL channels. DELTA is the difference between the NMOC
values determined by Radian channels and the NMOC values determined by ASRL.
PDELTA averages 3.34%, indicating that DELTA is symmetrical about zero.
APDELTA is 16.76%, which is slightly higher than the APDELTA mean of 15.88%
for 1987. Table 4-10 compares Radian NMOC analyses with ASRL NMOC analyses,
by Radian channels. APDELTA values are 14.20%, 18.81%, 18.92%, and 14.89%
comparing the ASRL channel with Radian Channels A, B, C, and D, respectively.

PDELTA averages are +1.78%, -3.91%, +8.28%, and +5.30% for ASRL versus Radian
Channels A, B, C, and D, respectively.
Table 4-11 compares repeated analyses of site samples by the EPA-ASRL
GC/FID instrument and the EPA-QAD PDFID instrument. The results show that
PDELTA averaged -1.51%, while APDELTA averaged 15.70 percent. The table shows
that the ASRL concentrations average 1.51% lower than the QAD concentrations.
Radian concentrations were 1.64% lower than QAD concentrations. APDELTA
between ASRL and QAD concentrations averaged 15.70%, whereas APDELTA for
Radian and QAD concentrations averaged 11.76 percent.
Of NMOC concentration measurements, the comparison between Radian and the
EPA-QAD channel represents between-laboratory comparisons for the PDFID
method. Comparisons between the Radian channels and the EPA-ASRL channel are
between-laboratory and between-method comparisons.
Table 4-12 summarizes statistics for repeated analyses on Radian
channels. The QAPP specified the channel pair to be involved with the
repeated analysis each day. The mean APDELTA was the average percent
difference between the second and the first analysis and was 10.06% for the
overall data set. Table 4-13 shows the statistics for repeated analyses by
Radian channel pairs. Table 4-14 gives the 95% confidence intervals for the
mean differences by channel pairs. Figure 4-25 plots the means and 95%
confidence intervals listed in Table 4-14. The squares on Figure 4-25 locate
the mean difference for each channel pair. The vertical lines span the 95%
confidence intervals of the mean differences.
4.4.2 Quality Control Chart
A quality control chart was developed for the 1988 replicate analyses and
is shown in Figure 4-26. The control chart plots percent difference for the
replicate analyses versus Julian date, 1988. The mean line,/* , which is
nearly coincident with zero, and two sets of horizontal control lines are
shown. Control lines at \L +2a and /A +3 a are shown on "the quality control
chart. The percent difference for the control chart is defined as:
% difference = ((NMOC for 2nd analysis - NMOC for 1st analysis) /
(Mean NMOC for both analyses)) * 100.

The 2-<7 limits, i .e.,/z+2 a, are termed the warning limits; the
3-a limits, (i±3a t are called the control limits. The control chart was
consulted frequently to see if consecutive replicate determinations were
outside the warning or control limits. In only one instance, about 1988
Julian date 184, did consecutive determinations occur outside the warning
limits. In no case were consecutive determinations outside the 3-cr control
limits. Two or three consecutive determinations outside the warning limits
give some cause for concern, but two or three consecutive determinations
outside the 3-a limits indicate that something is out of control in the
sampling and/or analytical system. As seen in the control chart, in no case
was the sampling and/or analytical system out of control. To investigate the
nature of the imprecision, or percent difference, the data were examined to
determine if percent difference was a function of the average NMOC
concentration level. This analysis is given in Section 4.4.3.
4.4.3 Precision Profile
The replicate percent differences were plotted against average NMOC
concentration for the replicate pair, and are shown in Figure 4-27. It is
clear from the figure that as the NMOC concentration falls below 1.0 ppmC, the
imprecision increases. One of the major causes of imprecision at lower
concentrations is instrument noise. Since instrument noise is essentially
independent of NMOC concentration, the portion of response attributed to noise
increases at lower NMOC concentrations. These facts combine to show an
increased imprecision at lower NMOC concentrations.
The NMOC concentration and percent difference for 221 replicate analyses
were sorted by NMOC concentration and divided into the eleven NMOC size groups
shown in Table 4-15. In the table, below 1.0 ppmC, the size increments are
0.100 ppmC, and show average NMOC concentration (assuming random variable,
normally distributed), minimum percent difference, average percent difference,
average absolute percent difference, and maximum percent difference for each
NMOC size group. The data in the table are plotted in Figures 4-28 and 4-29.
Figure 4-28 shows large fluctuations of average percent difference
between about -6% and +5% difference below an average NMOC concentration of
1.0 ppmC. Above 1.0 ppmC the average percent difference is below 3.0 percent.

A more striking profile of the replicate precision is seen in Figure 4-29 in
which average absolute percent difference is shown to decrease dramatically as
the NMOC concentration increases. When the NMOC concentration increases above
1.0 ppmC, the average absolute percent difference levels off at about
4 percent. Figure 4-29 also shows the overall average absolute percent
difference for all 221 replicates to be about 9.3 percent.
This analysis shows that as the NMOC concentration decreases below
0.500 ppmC, the imprecision of the measurement increases dramatically.
Similar results are universally found in analytical instrumentation.
4.4.4 Local Ambient Samples
Table 4-16 presents the overall statistics for local ambient samples.
These data include comparisons among Radian channels and EPA channels. The
mean differences and the mean percent differences are both near zero, which
indicates that they are random variables. The overall mean absolute percent
difference (APDIF) is 8.17%, which is lower than the precision for repeated
analyses (10.06%).
Table 4-17 presents the same information separated into two cases, by
the Radian analysis order. The upper part of Table 4-17 shows statistics for
the local ambient sample analyzed first by Radian. The lower part of
Table 4-17 shows statistics for the local ambient sample analyzed first by the
EPA laboratories, Channels QAD and ASRL.
Table 4-18 shows statistics for local ambient samples by analysis order
and channel pair. Mean absolute percent differences range from 3.12% for
Radian Channel Pair B-A for Radian second analysis order to 18.68% for Channel
Pair QAD-ASRL for Radian second analysis order, averaging 8.17% overall.
Tables 4-19 and 4-20 use data extracted from Table 4-18 and add the 95%
confidence intervals for the mean values of DIF. For example, from the
Table 4-19, for the channel pair C-A, the mean DIF is 0.002 ppmC, indicating
that the average NMOC concentration determined for the local ambient samples
was larger for Channel A than for Channel C by 0.002 ppmC. Figures 4-30 and
4-31 display the data from Tables 4-19 and 4-20 graphically and indicate no
significant difference, at the 0.05 level of significance, between the channel

pair mean differences and zero. The channel pairs containing QAD for Figure
4-30 show mean differences greater than zero.
Table 4-21 presents comparisons between percent differences in NMOC
concentrations for all channel pairs. Overall trends in the data are
difficult to discern with the exception of the fact that the standard
deviations of the differences for the site samples are larger than the
corresponding mean differences. This is true for all 30 comparisons for the
local ambient samples.
The results in Table 4-17 show that the order of analysis by one
laboratory does not make a significant difference in the measured NMOC value.
Table 4-18 shows that there is no significant difference in the measured NMOC
level between Radian and EPA channels. Table 4-18 also shows no significant
difference between the NMOC analysis by the PDFID and the. GC/FID speciated
method of analysis. There are no significant differences between Radian
channels.
4.5 DUPLICATE SAMPLE RESULTS
Throughout the 1988 NMOC Monitoring Program, duplicate samples were
collected once every two weeks at each site. Each duplicate was analyzed by
Radian for its NMOC content.
Table 4-22 summarizes statistics for NMOC, DIFF, ADIFF, PCDIFF, and
APCDIFF. The mean absolute percent difference between the duplicate samples
was 8.72 percent. The absolute percent difference ranged from zero to
68 percent. Table 4-23 summarizes the statistics for duplicate analyses by
site code. The mean absolute percentage differences between duplicates ranged
from 2.17% for CLOH to 20.4% for M1TN.
These results are lower than in 1986 and 1987, representing good
precision. The analytical error for repeated analyses was 10.06%, while the
precision for duplicates was 8.72 percent. Because the duplicate results
include sampling and analysis precision, while the replicate (or repeated
analysis) precision relates only to analytical error, the duplicate absolute
percent difference is expected to be greater than the replicate absolute
percent difference. The fact that the results given above appear to show an
opposite trend results from the use of different sets of samples for
duplicates and replicates.

4.5.1 Sampling and Analysis Precision
Beginning July 14, the replicate analyses were performed on duplicate
samples. The replicate analyses were performed on the same Radian channels on
the day after the initial analyses. The intention was to evaluate the
relative importance of sampling variability and analytical variability. The
data for 50 pairs of duplicates are summarized in Table 4-24. Each site, on a
site-specific day, took duplicate samples. The analysis of each duplicate was
performed on successive days by two or three injections each day. There were
on the average 4.27 injections per duplicate sample for both replicate
analyses. Replicate Mean 1 is 'the average of the NMOC analyses, expressed in
ppmC, of two or three injections for the first replicate analysis; and
Replicate Mean 2 is the average of the NMOC analyses in ppmC of two or three
injections for the second replicate analyses, which took place on the day
after the first replicate analysis. Replicate percent difference is the
difference of the second replicate mean minus the first replicate, divided by
the mean and multiplied by 100. Column 9 in the table gives the absolute
percent difference for replicates, which averages 7.009% as seen in the table.
The average percent difference is 2.005 percent. For each sample the table
also shows the overall sample (or duplicate) mean, the percent difference for
the two duplicates, and the absolute percent difference for the duplicates.
Note that the overall percent difference for duplicates is -3.946% and the
overall absolute percent difference for duplicates is 7.552 percent. The
average percent differences and average absolute percent differences for
duplicates are larger than for replicates, as expected.
To separate the sampling variability from the analytical variability an
analysis of variance was performed with the following hierarchical model:
(NMOC). jkf » M+ S.
Where: (NMOC)^ .^» = a measurement of NMOC in ppmC;
fi = the overall mean value for the NMOC measurement;
S. = sample i for a given site and day;
D./.x = duplicate j of sample i, j - 1,2;

= Analytical injection £, £ = 1,2, or 3; and
e£(iik) = re£idual error.
The hierarchical (or method) model was chosen because each duplicate pair
is independent of each other duplicate pair, and likewise the replicates and
injections are nested in the experimental design. No interaction terms are
relevant in a nested design.
The Analysis of Variance (ANOVA) showed that Rk and 1^ factors were not
significantly different from zero, so the ANOVA model was collapsed to:
(NHOC),jk - n* S, + D.(1) t «k(u).
where the variables are defined as before. The ANOVA is given in Table 4-25.
Table 4-26 lists the components of variance for the 50 samples for which
duplicates and replicates were analyzed. The mean squares in Table 4-26 are
2
taken directly from the ANOVA Table 4-25. Solving for <7. , the variance for
2
analyses, and (7^ , the variance for duplicates gives:

were in control. From 1988 Julian date 160 through about 190 the control
chart shows a number of excursions outside either the warning limits (fjL±Za)
or the control limits (f*-±3o). Similarly, after 1988, Julian date 250 there
were several excursions outside the warning limits. There was, however, no
indication (more than two successive points outside either the warning limits
or the control limits) of loss of control. It is necessary to keep in mind
that although the analytical systems were centrally located, the sampling
systems, which contributed significantly to the overall system variability,
were located at 45 sites across the country. The quality control chart shows
that in June 1988, as most of the sites were beginning sampling, there was
increased variability at several sites, but for the rest of the monitoring
program, the duplicate sampling and analysis was in good control.
4.5.3 -Precision Profile
As in the case of replicate analyses, the data show that below 1.0 ppmC
NMOC concentration, percent difference between duplicate analyses increases
significantly. Figure 4-33 shows percent difference plotted against average
NMOC concentration. Table 4-27 summarizes the duplicate imprecision into
el-even data sets summarized by average NMOC concentrations ranging from 0.050
to 4.50. Average percent difference and average absolute percent difference
from Table 4-27 are plotted in Figure 4-34 and 4-35, respectively. The trend
of increasing imprecision at NMOC concentration levels below 1.0 ppmC is
clear.
4.6 CANISTER PRESSURE RESULTS
Canister pressure results-for the NMOC Monitoring Program are important
to be sure that the ambient air samples obtained are representative. The NMOC
sampling systems are designed to obtain an integrated ambient air sample
between 6:00 a.m. and 9:00 a.m., or at other programmed intervals. The flow
rate of the sample into the 6-L canister is controlled by a critical orifice,
which requires a pressure drop across the orifice sufficiently high to
maintain sonic velocity in the orifice. If sonic velocity can be maintained
in the orifice for the entire sampling period, then the flow rate into the
canister is constant and the sample is properly integrated. The temperature
must also be assumed to remain constant over the sampling period.

-------
As the final canister pressure increases, there is a pressure downstream
of the sonic orifice at which the sonic velocity can no longer be maintained.
Canister pressures are being measured to obtain a better understanding of the
range and magnitude of pressures being generated by the NMOC sampling systems.
Canister pressure data are given in Tables 4-28 and 4-29 for both single-
canister samples and duplicate samples. The pressures reported in Tables 4-28
and 4-29 are the canister sampling pressures measured in the field and may be
different from the canister pressure measured immediately before analysis in
the laboratory. A significant decrease between the field sampling pressure
and the laboratory value might indicate a leak. The canister was leak tested
when this occurred.
Table 4-28 gives statistics for single and duplicate samples. Single
sample canisters average 14.6 psig and duplicate samples average 16.8 psig.
Standard deviations are 2.6 and 2.5 psig, respectively. The data show little
skewness, but the kurtosis is well below the expected kurtosis for a normal
distribution.
The distributions of pressure for single samples and duplicate samples
are given in Table 4-29 and indicate that the pressure distributions are
approximately normally distributed. The small values for skewness
(Table 4-28) and the fact that the means and medians are very close to being
equal support the hypothesis that the distributions are approximately normal.
4.7 CANISTER CLEANUP RESULTS
Prior to the start of the 1988 NMOC Sampling and Analysis Program all of
the canisters were cleaned and analyzed for their NMOC content to establish
canister initial conditions. The resulting analysis with cleaned, dried air
that had been humidified averaged 9.4 area counts (0.0029 ppmC), ranging from
zero to 76.50 area counts (0.024 ppmC). Any canisters that produced more than
0.025 ppmC were recleaned.
Continual monitoring of the cleanup was important to ensure that there
was negligible carryover from one site sample to the next. The daily canister
cleanup procedure is described in detail in Section 3.4. The NMOC content was
below 0.030 ppmC and cleanup was considered to be satisfactory.

Percent recoveries, or percent cleanup, in 1988 averaged 99.689% (99.374%
in 1987, 99.891% in 1986, and 99.898% in 1985), ranging from 95.28% to
100 percent. The reported percent cleanup figures should be considered
minimum values. The actual percent cleanup was greater than the reported
values because, after the percent cleanup was measured, the canister was
evacuated a third time before being shipped to the site.
4.8 EXTERNAL AUDIT RESULTS
Primary measures of accuracy were calculated from the results of the
analysis of audit samples provided by EPA-QAD. Results are reported in terms
of percent bias, relative to the EPA standards.
Audit samples of propane provided by EPA-QAD were referenced to NBS SRM
propane No. 1668B. Each Radian channel and the EPA-ASRL channel analyzed each
audit sample. The results of these analyses are given in Table 4-30. Audit
sample bias, percent bias, and absolute percent bias are shown in Table 4-31.
In Table 4-31, all bias measurements are relative to the QAD results.
Overall Radian average bias was 2.73% indicating Radian channels averaged
2.73% lower than the EPA-QAD reference values. Radian mean bias ranged from
1.33% for Channel B to 4.52% for Channel D. The overall average absolute
percent bias for the Radian channels was 3.40 percent. These accuracy
measurements show excellent agreement with the reference values, and lend
confidence to the 1988 NMOC concentration results determined on all the Radian
channels.
The EPA-ASRL channel averaged +4.5% bias, relative to EPA-QAD.
Figures 4-36, 4-37, 4-38, and 4-39 show the audit bias results for the Radian
channels versus the reference values provided by EPA-QAD. Figure 4-40 shows
the audit bias results for EPA-ASRL versus EPA-QAD.
4.9 DATA VALIDATION
The secondary backup disks were updated daily on 20 megabyte hard disks.
At the completion of the sampling and analysis phase 10.6% of the data base
was checked to verify its validity. Items checked included original data
sheets, checks of all the calculations, and data transfers. In making the
calculations for the final report and other reports, corrections were made to
the data base as errors or omissions were encountered.

A total of 4,171 NMOC measurements by Radian are in the 1988 NMOC data
base. This includes 3,497 site samples and 217 repeated analyses of site
samples by Radian channels. In addition, 83 QC samples, 32 local ambient
samples, and 3 external audit samples were each analyzed by Radian channels.
Each of these samples had a unique sample I.D. number, with the exception of
the 217 repeated analyses. Each NMOC datum has 54 individual items associated
with that datum.
Eleven percent of the data base (444 cases out of 4,171 data points) was
selected at random and validated according to the procedure outlined below.
A. Calibratipn factors were checked.
1. The area count from the strip chart that was used to determine
the calibration factor was examined to verify that the data had
been properly transferred to the calibration form.
2. The calibration form was examined to verify that the calcula-
tions had been correctly made.
3. Each datum on the disk was compared to the corresponding datum
on the calibration sheet for accuracy.
B. Analysis data were checked.
1. Area counts were verified from the appropriate strip chart.
2. Calculations were reverified on the analysis forms.
3. Each datum on the disk was compared to the corresponding item on
the analysis form.
C. Field data sheet was checked.
1. Each datum on the disk was compared to the corresponding datum
on the field data sheet.
The error rate calculated in terms of the number of items transferred from the
original data sources. For each NMOC value in the 1988 data set, 54 items
were transferred from original sources to the magnetic disks. In the data
validation study each item on the disk was compared with the corresponding
value on the original source of data. Six errors were found (and corrected)
for an expected error percentage of 0.025.
can.107 4-99
-------
Each time the data file was opened and a suspected error found, the error
was checked against the original archived documents, and corrected where
appropriate.
4.10 NMOC MONITORING PROGRAM RECORDS
The quality assurance records developed by Radian for this project are
extensive and will be preserved as archives. One of the most important objec-
tives of the study was to develop a data base that was well planned and docu-
mented, and contained NMOC data of known and verifiable quality. Achieving
that objective has involved keeping and preserving a number of records that
trace the project from planning through reporting.
4.10.1 Archives
In order to keep detailed records that document the quality of the
measurements made, Radian developed the following original material:
• Quality Assurance Project Plan;
• Notebooks;
• Field Data Sheets;
• Laboratory Calibration Sheets;
• Laboratory Analysis Sheets;
• Chromatographic Strip Charts;
• EPA-ASRL and EPA-QAD NMOC Results;
t Bi-weekly, Monthly Reports to EPA;
• Memoranda and Correspondence; and
t Final Report.
In addition to the above items, several papers to be presented at
technical meetings and symposia and published in technical journals will be
added to the archives.
The QAPP was the Quality Assurance Project Plan and the workplan. It
was designed according to the EPA Quality Assurance Guidelines, and set the
pattern of steps necessary to document and control the quality of the data
obtained throughout the study.
Several notebooks were necessary to maintain day-to-day records of the
project. Field and laboratory data sheets were designed in advance, so that
cah.107 4-100
-------
the data recorded appeared in a logical sequence and filled in blanks on the
sheet. Additional space was provided for other comments. Each NMOC analysis
was assigned a unique Radian Identification Number. Field data sheets and
shipping records accompanied the canisters in transit.
4.10.2 Magnetic Disks
In order to manage the data base for report generation and data analysis,
pertinent data from the various data sheets and notebooks were transferred to
20 megabyte magnetic disks. Lotus 1-2-3* and PCFile+» software were used in
the construction of the data base. Statistical calculations were done using
SYSTAT® software. The data access is rapid and in a convenient form. The
primary 20 megabyte magnetic disk has three backup disks.

5.0 NMOC DATA ANALYSIS AND CHARACTERIZATION
The purpose of this section is to characterize the NMOC data
qualitatively as well as quantitatively. The NMOC data are shown to fit a
two-parameter lognormal distribution better than a normal Gaussian
distribution. The summary NMOC data for the sites of the 1988 study are given
in Appendix E.
5.1 OVERALL CHARACTERIZATION
Figure 5-1 gives a stem-and-leaf plot of the 1988 Morning Site NMOC data
along with statistics for NMOC. The stem-and-leaf plots show the actual NMOC
concentrations truncated to two decimal points. The digits to the left of the
vertical open space are called stems and the digits to the right of the open
space are the leaves. The data are sorted from the smallest at the top of the
graph to the largest at the bottom of the graph. The minimum NMOC value
measured was 0.016 ppmC and is shown as "0 1" on the first row at the top of
the plot. The maximum NMOC concentration measured was 5.890, shown as
"58 9" at the bottom row of the chart. The plot shows 3,069 leaves, one for
each NMOC Morning Site datum in the 1988 program. The H's in the open
vertical space locate the stem and leaf for the upper and lower hinges, and
the M locates the stem and leaf for the median. The median separates the
sorted data into two equal halves; the hinges (or quartiles) separate each
half into quarters. The "H spread" or inter-quartile range is the difference
between the NMOC values of the two hinges.
Statistics shown for NMOC are number of cases, minimum, maximum, mean,
standard deviation, standard error, skewness, and kurtosis. Each NMOC
determination is the average of two or three injections of the site sample.
The standard error is the standard deviation divided by the square root
of the number of cases. Positive skewness is a third moment about the mean
value, and characterizes a tail to the right of the mean value. A normal
Gaussian distribution has a skewness of zero. The skewness of 2.4 for the
1988 NMOC data suggests a lognormal frequency distribution; that is supported

-------
by the fact that for the logarithm of the NMOC value (In(NMOC)) (see
Figure 5-2), skewness equals -0.397, which is close to zero. Kurtosis is the
fourth moment about the mean and relates to the pointedness of the
distribution. A distribution more pointed than a normal distribution, having
the same standard deviation, has a kurtosis greater than 3.0.
In Figure 5-1 there is a small node in the region of NMOC concentration
from 1.5 to 2.5 ppmC. A similar node was observed in the 1987 NMOC Monitoring
data. Investigation of the sources of these data revealed that 20 of the
readings were from Cleveland, Ohio; 11 from Phoenix, Arizona; 10 from
Miami, Florida; 10 from Houston, Texas; 9 from Newark, New Jersey; and 8 from
Austin, Texas. A total of 27 sites contributed to the node, but no general
pattern was discerned. The St. Louis, Missouri, site was the only site that
contributed to the node both in 1987 and 1988. " The node in 1987 was in the
NMOC concentration region from 1.85 to 2.5 ppmC.
Figure 5-2 is a stem-and-leaf plot of the 1988 In(NMOC) data. The plot
shows an approximately symmetrical distribution (skewness - -0.397). The
kurtosis equal to 0.718 indicates the In(NMOC) distribution to be less pointed
than a normal distribution. The node seen on Figure 5-1 is not apparent in
Figure 5-2.
The shape of the stem-and-leaf plots suggests a lognormal distribution.
Figures 5-2 and 5-3 support the lognormal distribution hypothesis for NMOC.
The vertical scales in Figures 5-2 and 5-3 are arranged so that if the
cumulative frequency of occurrence of NMOC were normally distributed, the
numbers would plot into a straight line. The line in Figure 5-3 has a
noticeable concave downward trend, indicating that the data do not fit a
normal distribution well. Figure 5-4 plots the logarithm of NMOC on the same
vertical scale. The fact that the digits on the graph plot into approximately
a straight line supports the hypothesis that the NMOC data are approximately
lognormally distributed. The asterisks on the graph indicate the location of
a single datum. Integers, such as 2, 6, or 9, show the location of the
corresponding number of data points. The number 999 shows the approximate
location of either 27 data points or 99 + 9 data points. The results,

although qualitative, show a dramatic difference between the normal and
lognormal hypotheses, and suggest that the latter more nearly describes the
NMOC data. Figure 5-4 is labeled a "Normal Probability Plot," but since the
independent variable is the logarithm (to the base e) of NMOC, if the relation
between the EXPECTED VALUE and In(NMOC) is linear, a lognormal distribution
obtains.
5.2 MONTHLY VARIATIONS, 1984 - 1988
Table 5-1 partitions the NMOC data for the summer of 1988 into groups
which correspond to monthly intervals. The time interval for April
corresponds to Julian dates 92 to 121; for May, 122 to 152; for June, 153 to
182; for July, 183 to 213; for August, 214 to 244; and for September, 245 to
274.
The data for September appear higher than for June, July, or August, but
no clear trend is seen for the summer of 1988.
Figures 5-5 through 5-10 give the stem-and-leaf plots of the NMOC data
for April, May, June, July, August, and September 1988, respectively. All the
plots show the general shape of lognormal distribution. May and June 1988
data are for only four Florida sites, MIFL, M2FL, T1FL, and T2FL, and should
not be considered comparable to the other monthly graphs. The data for June,
July, August, and September may be considered typical of the 45 sites tested
during the indicated time period. Monthly mean NMOC emissions are plotted in
Figure 5-11 for 1984, 1985, 1986t 1987, and 1988. No general trends are
evident for the years shown. For four of the five years, September means are
higher than August means, and for four of the five years, July means are less
than June means. At present, however, it must be concluded that random
behavior is responsible for apparent month-to-month changes.
During the 5 years of the NMOC Monitoring Program, three sites
participated in the program for all five years. Two sites have been in the
program 4 years; 7 sites for 3 years; 18 sites for 2 years; and 61 sites for
only 1 year. In all cases; however, the sites were urban sites, but it is
difficult to draw conclusions from year to year because of the different site
makeup.

Figure 5-11 shows monthly means for April through September. The April
and May NMOC monitoring data were from only four Florida sites, MIFL, M2FL,
T1FL, and T2FL. The remainder of the points located on the 1988 trend line
included data from all 45 NMOC Monitoring Program sites. Month-to-month
trends are not immediately apparent, but it is clear that since 1984, the NMOC
level has decreased about 25 percent.

6.0 RECOMMENDATIONS
Based on the experiences and results of the 1988 NMOC Monitoring Study,
certain recommendations can be made with respect to equipment design and
validation procedures.
6.1 OPERATING PROCEDURE CHANGES
Current operating procedures call for the use of dry propane standards
and external audit samples. The experimental design recommended would cover
the present NMOC span of 0 to 9 ppmC, and at least 3 levels of-humidity: zero,
low (-10%), and medium (-30%) relative humidity. The effect of humidity on
propane calibration (and audit) results is currently unknown and should be
determined.
»
6.2 VERTICAL STRATIFICATION STUDY
In 1987 and 1988 ambient air samples were taken at ground level (3 to
10 meters) and at the 1197-foot (364.9 meter) level. In 1988, an additional
site was located on top of the World Trade Center in New York, a height of
over 1000 ft. It is recommended that the study continue at these sampling
locations and that at least one more level (at 100 meters or some other
appropriate height above ground level) be sampled at the same site location.
At the same time, site barometric pressure and site wind velocity and
direction data should be obtained at each sampling level. These samples
should be analyzed for NMOC content as well as for the air toxics compound
concentrations. The information gained from such a study would be useful in
validating various atmospheric model predictions.
6.3 SEASONAL NMOC STUDIES
Data derived in a study qualifying NMOC and NO in seasons other than
summer could be useful in understanding the relationship of NMOC to NOX and
meteorological conditions. Currently a year-round study for 24-hour air
toxics ambient air samples is being conducted. No study is currently in
progress to determine seasonal NMOC concentration changes.
-------
6.4 DIURNAL STUDIES
Some interest has been expressed in diurnal NMOC concentration data,
particularly from 6:00 a.m. to 6:00 p.m. In a recent proposal Radian
suggested various diurnal sampling plans:
o Four 3-hour samples: 6:00 to 9:00 a.m.; 9:00 a.m. to Noon; Noon to
3:00 p.m.; and 3:00 to 6:00 p.m.;
o Four 3-hour samples: 6:00 to 9:00 a.m.; Noon to 3:00 p.m.; 6:00 to
9:00 p.m.; and midnight to 3:00 a.m.; and
o Use of automatic PDFID apparatus providing four NMOC concentration
measurements per hour, 24 hours per day.
Such data are necessary in devising mathematical models to predict NMOC
concentrations 24 hours per day. 'The data would also be useful in predicting
24-hour health risks. The same samples could be analyzed by 6C/MD to
determine the concentration levels of the 38 UATMP target compounds.
6.5 CANISTER CLEANUP STUDIES
Prior to July 14, 1988, the canister cleanup procedure was as follows:
I. Canister was evacuated to an absolute pressure of about 5 mm Hg;
2. Canister was pressurized to 20 psig with dried, cleaned air that hac
been humidified;
3. Steps 1 and 2'were repeated;
4. Canister was evacuated a third time;
5. • The canister was pressurized a third time with cleaned, dried air;
6. The canister was analyzed for NMOC concentration. If the NMOC
concentration was less than 0.030 ppmC, the canister was declared tc
be clean; and
7. The canister was evacuated a fourth time and sealed for shipment.
After July 14, 1988, the canister procedure was revised, as follows:
1. Steps 1, 2, and 3 above were performed; and
2. Steps 6 and 7 were performed.
cah.108 6-2
-------
If in Step 6 for either of the cleanup procedures, the NMOC concentration was
greater than 0.030 ppmC, the cleaning procedure was repeated until the
acceptance criterion was met.
Radian has proposed initiation of several studies to determine whether
the present canister cleanup procedure is adequate to prevent significant
carryover of organic compounds from one canister to the next. These studies
are needed since equilibration in a canister may take a week or longer.
The effect of sample pressure on the measured NMOC concentration is not
clear. Ambient air samples are sufficiently humid so that at 15 psig, liquid
water condenses inside the canister. The liquid water migrates to the
canister walls which affect the adsorption equilibrium, and at the same time,
provides a medium for further depletion of the vapor phase organic compounds
because of the solubility of the organics in water. Equilibration under these
conditions would take longer, perhaps 30 days or longer, and the effect on the
measured air sample NMOC (and UATMP target compounds) concentration has not
been determined. These effects, however, are probably not significant for the
NMOC measurements.
The present cleanliness criterion for canisters is that if the NMOC
concentration in Step 6 is less .than 30 ppbC, the canister is declared to be
clean. This measurement is taken under transient conditions. For a more
meaningful cleanliness criterion, canisters after cleaning should be filled
with cleaned, dried air that has been humidified to sample pressure (15 psig)
and allowed to stand at least 7 days and analyzed for their NMOC
concentration.
Radian has proposed to undertake a study to ensure a better understanding
and measurement of the effectiveness of the canister cleanup procedure. The
present canister cleanup procedure is thought to be adequate for the NMOC
program, since the concentrations of interest are at the ppmC level. For the
UATMP, the concentration levels are at the ppbv levels, i.e., 0.01 to 50 ppbv,
and the present canister cleanup procedure may not be sufficient to prevent
significant carryover of target compounds from one sample to the next for the
UATMP. A study of the canister cleanup procedure for the UATMP would also
further validate the present cleanup procedure for the NMOC Monitoring
Program.

6.6 COORDINATED SAMPLING AT NMOC SITES
It is recommended that where possible the following sampling take place
at NMOC sites for the 1989 monitoring programs:
t NMOC samples;
t Aldehyde samples;
t 3-hour air toxics compounds; and
t UATMP sampling (at least 38 target compounds).
This kind of program would effect some economy in setting up and monitoring
the sampling program, and also provide some opportunity for cross-correlation
of the results.
6.7 FIELD AUDIT
It is recommended that a field audit be designed and conducted at several
NMOC sites during the 1989 Monitoring Program. It is suggested that one field
audit per month be performed at an NMOC site during June, July, August, and
September 1989. The field audit should use at least one standard of known
NMOC concentration and should collect duplicate samples plus a zero-air blank
for each site.
6.8 DUPLICATE SAMPLE AND REPLICATE ANALYSES
It is recommended that during the 1989 NMOC Monitoring Program,
replicated analyses be performed only on duplicate samples. It is further
recommended that the replicate analyses on a particular canister be performed
on the same Radian channel. This recommendation will be incorporated into the
1989 Quality Assurance Project Plan for the NMOC Monitoring Program.

7.0 THREE-HOUR AIR TOXICS DATA SUMMARY
The 1988 NMOC Program and UATMP included three-hour ambient air samples
at 13 NMOC urban sites (See Table 7-1) located in the contiguous United
States. Overall concentration results are reported in parts per billion by
volume (ppbv) in Section 7.1, and site-specific results are given in
Section 7.2.
Analyses were done by a GC/MD system using flame ionization detection
(FID), photoionization detection (PID), and electron capture detection (ECD).
Compound identification was made using a combination of retention time, ratios
of PID/FID and/or ECD/FID responses, and analyst experience and judgement.
Quantitation was done using the FID response, with the exception of
halogenated compounds that were quantitated using the ECD. If there was an
indication that the quantitation detector response for the target compound had
interference from an unknown source quantitation was performed on one of the
alternate detectors if applicable. Table 7-1 indicates the number of 3-hour
samples taken for GC/MD analyses to speciate for 38 UATMP compounds. About 10
analyses were performed on samples from each site, with the exception of CLOH.
One of the samples from each site was taken in duplicate and the analysis of
one of the samples from each site was replicated. Two of the samples from
each site (with the exception CLOH) were analyzed by gas chromatography/mass
spectrometry (GC/MS) for confirmation of compound identification.
Three-hour air toxics samples were regular NMOC Monitoring Program
samples that were collected in 6-L stainless steel canisters from 6:00 a.m. to
9:00 a.m. The final canister pressure was about 12 psig. The NMOC samples
that were speciated by GC/MD were selected at random during the summer. Each
selected sample was first analyzed by the PDFID method for its NMOC
concentration. Then the canister pressure was bled to atmospheric pressure
and the canister bellows valve was closed. The canister was allowed to
equilibrate at least 18 hours before the GC/MD analysis was performed.

7.1 OVERALL RESULTS
Concentrations of the air toxic compounds detected are summarized in
Table 7-2 for the 1988 3-hour ambient air samples that were speciated. The
table shows the number of cases (samples), the percent of cases in which the
compound was identified, the minimum, maximum, and mean (arithmetic average)
concentrations of the compound in ppbv. The target compounds identified fall
into at least four categories: (1) those occurring in more than 70% of the
samples tested, (2) those occurring in from 10% to 27% of the samples,
(3) those identified compounds occurring in less than 10% of the samples, and
(4) those not identified in any of the 3-hour air samples at concentrations
above their method detection limits. These results are summarized in
Table 7-3. One of the most striking observations in examining of the data of
Table 7-3 is that there were no target compounds identified in the percent
frequency range from 26.7% for tetrachloroethylene to 72.5% for
1,1,1-trichloroethane. Another observation derived from these results is that
none of the bromine-containing compounds were identified at concentrations
above their detection limits in any of the 3-hour ambient air samples analyzed
by GC/MD.
Overall concentrations ranged from 0.03 ppbv for 1,2-dichloroethane to
57.22 ppbv for chloroform. The overall average concentration of the target
compounds was 2.95 ppbv.
7.2 SITE RESULTS
Table 7-4 gives 3-hour ambient air concentrations by site code for the 38
target air toxics compounds. The overall site means range from 0.64 ppbv for
BRIL to 5.05 for D2MI. Appendix I tabulates the complete analytical results,
and includes the NMOC concentrations for each of the 3-hour air toxics
samples. There appeared to be little correlation between the NMOC
concentrations and overall air toxics compound concentration.

8.0 THREE-HOUR AIR TOXICS TECHNICAL NOTES
This section describes the equipment used to sample and analyze the
3-hour air toxics samples. Also described are sample handling procedures,
sampler certification procedures, standards generation and instrument
calibration procedures, compound identification procedures, GC/MS compound
identification confirmation, quality assurance/quality control procedures, and
data records for the 3-hour air toxics compounds.
8.1 SAMPLING EQUIPMENT AND INTERFACE
The sampling equipment for the 3-hour air toxics samples was the NMOC
Monitoring Program sampling equipment described in Section 3.1. The original
sample was collected as an integrated ambient air sample from 6:00 a.m. to
9:00 a.m. with a final sample pressure of about 16 psig. As stated above,
after NMOC analysis the canister was bled to atmospheric pressure and allowed
to stand at least 16 hours before being analyzed by GC/MD.
An interface system was designed and built by Radian Corporation to take
a sample from the canister and inject it into the gas chromatograph for
analysis.
Figure 8-1 shows the GC/MD system including the Sample Interface System,
Analytical System, and Data System. The sample interface takes a 250-mL
sample from the canister, draws it through Trap Assembly 1 and condenses all
the water and organic compounds, with the exception of methane, in the air
sample drawn from the canister. Trap Assembly 1 is a cryogenic, liquid argon
trap packed with glass beads. The cryogen is removed, and an electrical
heater quickly heats Trap Assembly 1, vaporizing the water and organic
compounds condensed from the canister sample.
8.2 SAMPLER CERTIFICATION
The NMOC sampler described in Section 3.0 used all stainless steel
fittings. Assuming all the sample lines and fittings are clean of organic
compound contaminants, the only other point in the sampling system where

organic contaminants may enter the ambient air sample collected in the
canister is from seating material and packing material in the solenoid valve.
The solenoid valve is connected to the electronic timer which controls the
beginning and ending of the 3-hour sampling period.
In order to certify the NMOC samplers before their installation in the
field, the samplers were tested in Radian's Research Triangle Park Laboratory
for possible contamination. Cleaned, dried air that had been humidified was
pumped through the NMOC sampling system for about 48 hours and then a 3-hour
sample was collected. The sample was analyzed for a selected group of target
compounds. Results showed that there were no target compounds in the
certification sample haying a concentration above the GC/MO method detection
limit.
8.3 STANDARDS GENERATION
The GC/MD analytical equipment was calibrated daily with a gas mixture
that averaged 10 ppbv of each of the 38 target compounds at 70% relative
humidity.
The standard gas mixtures were generated by dynamic flow dilutions of
Scott certified gas mixtures with cleaned, dried air that had been humidified
with HPLC-grade water. The Scott gas mixtures were dry and contained in
cylinders under pressure at a concentration of about 120 ppbv per compound.
The concentration for each target gas in the Scott cylinder was certified to
+5% with the exception of the bromoform which was certified to +20 percent.
Figure 8-2 diagrams the dynamic flow dilution apparatus. One Scott
cylinder contained 18 of the air toxics target compounds, a second Scott
cylinder contained 11 target compounds, while the third Scott cylinder
contained the remaining 9 target compounds. The three Scott cylinders were
connected to Channels 1, 2, and 3 of the flow dilution apparatus. The fourth
channel was connected to a cylinder of zero-grade air by way of a catalytic
oxidizer that oxidized all of the hydrocarbon material in the zero-grade air.
The four mass flow controllers were set to flow rates that would give the
desired final concentration of the diluted gas.
The cleaned zero-grade air was partially humidified by bubbling part of
the air stream through HPLC-grade water contained in a stainless steel
cah.108 8-3.

canister. The wet and dry rotameters and all the mass flow controllers were
calibrated with a bubble flowmeter before being connected to the flow dilution
apparatus. All of the flow controllers, the connecting lines, and the mixing
flask were heat traced to reduce adsorption of the target compounds. The
temperature controller that regulated electrical current flow to the heat
tracing was set for 100°C.
To generate a standard, the following procedure is used. The canister
into which the standard is being mixed is connected to the flow dilution
apparatus at the bellows valve shown in Figure 8-2. The temperature
controller for the heat tracing is activated. The isolation valve is closed
and the vacuum pump turned on. The tubing, the canister, and the absolute
pressure gauge are all evacuated to about 5 mm Hg absolute pressure for at
least 15 minutes. The mass flow controllers are then set for the appropriate
flow rate to obtain the desired dilution and the humidifier, lines, and mixing
flask are purged for at least 10 minutes. The vacuum pump is then isolated
from the system and the isolation valve is opened to the diluted gas mixture.
The standard mixture fills the canister at a controlled rate until atmospheric
pressure is reached. The canister with the diluted standard is disconnected
from the flow dilution apparatus and allowed to equilibrate before use. The
barometric pressure and room temperature are also recorded.
In order to calculate exactly the concentration of each target compound
in the standard mixture, a correction is made for the residual gas in the
standard canister before the filling with the diluted gas is begun. A
correction also is made for the water vapor added to the dilution air.
8.4 CALIBRATION ZERO AND SPAN
Most of the compound quantitation is performed with the calibrated
response of the FIO detector. For purposes of compound identification and
quantitation (when there may be interference on the FIO detector} it is also
necessary to calibrate the PID and ECD responses. Initial calibration curves
for each compound were generated on all three detectors with calibration
standards at 1, 5, 10, and 20 ppbv. In addition to the usual response (area
counts) versus concentration curves, response times and response ratios for
PID/FID and ECD/FID were determined for each target compound.
cah.108 8-5
-------
The first run of the day was made using zero air to be sure that the
interface and analytical systems were free from contamination. Daily
calibration checks at about 10 ppbv to establish response factors were
performed as the second run of the day.
8.5 GAS CHROMATOGRAPH/MULTIDETECTOR ANALYSIS AND COMPOUND IDENTIFICATION
A Varian* 3700 gas chromatograph, configured with a PID in series with an
FID and an ECD operating in parallel, performed the air toxics analyses.
Fused silica was used for the detector-to-detector connections. The Air
Toxics Multiple Detector System is shown in Figure 8-3 and diagrams the
effluent splitter and multidetectors connected to the end of the Megabore*
DB-624 capillary column.
The entire GC/MD system is shown in Figure 8-1, including the sample
interface, the gas chromatograph/multidetector analytical system, and the data
handling system. Sample volumes for the GC/MD analyses were 250-mL.
Compound identification was performed using measured retention times and
ratios of PID/FID and ECD/FID responses. The analyst's skill and experience
was also needed in making a judgement about the presence or absence of a
target compound because of the variability of response times, and the presence
of interfering compounds.
8.6 GAS CHROMATOGRAPH/MASS SPECTROMETER ANALYSIS AND COMPOUND IDENTIFICATION
CONFIRMATION
Twelve of the 3-hour air toxics samples were analyzed by GC/MS for
compound identification confirmation following completion of the GC/MD
analyses. So that the sensitivity of the GC/MS compared favorably with that
of the GC/MD, the GC/MS was operated in the multiple ion detection (MID) mode,
and the sample volume was 500-ml (compared to 250-mL for the GC/MD analyses).
No comparison of the quantitative results for GC/MS and GC/MD was
examined, because the purpose of the GC/MS analyses was compound
identification confirmation only. This comparison is discussed below in
Section 8.7.4.

8.7 QA/QC DATA
Quality assurance and quality control in the 3-hour air toxics data
included a determination of minimum detection limits for both the GC/MD and
the GC/MS analytical methods. These determinations were linked with the
UATMP results, which are reported in Volume II of this report.
One of the objectives of the UATMP was to make the detection limits as
low as possible, recognizing that the lower detection limits may increase the
number of false positive or false negative identifications. Other quality
measures reported here involved analytical precision results from repeated
analyses, and sampling and analysis precision from duplicate samples.
Accuracy was assessed'for both the GC/MD and GC/MS using external audits
supplied by the EPA-QAD.
8.7.1 GC/MD and GC/MS Minimum Detection Limits
Minimum Detection Limits for-the GC/MD and GC/MS analytical systems used
in this study are given in Table 8-1. Detection limits for the GC/MD
analytical system are based on a sample approximately 250-mL in volume. The
sample volume for the GC/MS system was about 500-mL. The GC/MS was operated
in the MID mode, which detected specific ions representative of the 38 air
toxics target compounds.
8.7.2 Repeated Analyses
Repeated analyses were performed on nine site samples by GC/MD. The
analyses were performed on consecutive days with at least 24 hours between
removing samples from the canister. From these analyses there were 55 cases
in which a concentration for a target compound was found in both replicate
analyses. Statistics for these data are summarized in Table 8-2, showing the
overall minimums, maximums, and means of the mean concentrations, standard
deviations, coefficients of variation, and absolute percent differences for
the 55 replicate pairs. The absolute percent difference averages 8.542%,
which is excellent agreement.
The percent coefficients of variation are plotted against the replicate
sample means in Figure 8-4 and show that the largest contributions to the
overall variance occurs in the samples having means less than 2 ppbv.

Table 8-3 lists the cases in which a target compound was found in only
one of the replicate analyses. For all except one case, the concentration wa
below 1.0 ppbv, which suggests that the variability of the analyses at the
lower concentration levels may explain in part why one compound was seen in
one replicate analysis, but not in the other. Although the list of single
compound identifications is not long, no pattern to the behavior emerges.
8.7.3 Duplicate Sample Results
Eleven duplicate 3-hour ambient air samples were analyzed by GC/MD for
the 38 target compounds. Summary precision results are given in Table 8-4 in
terms of mean concentration and concentration range in ppbv. Other precision
statistics are given in terms of standard deviation, percent coefficients of
variation, and absolute percent difference. The data in Table 8-4 are
accumulated over all compounds and site locations.
The percent coefficients of variation ranged from -105.2% to 77.0%,
averaging -2.130 percent. These data are also plotted in Figure 8-5 and show
that the larger values of percent coefficient of variation are at the
duplicate mean concentrations below 2 ppbv.
Table 8-5 also shows that the imprecision is also compound specific.
Mean absolute percent difference for 1,3-butadiene is 57.384%; the
concentration range is 0.190 ppbv to 0.860 ppbv. For the other selected
compounds in Table 8-5, the absolute percent difference means ranged from
3.876% to 12.401 percent. The precision for the 3-hour air toxics compounds
is good with an overall average absolute percent difference of 13.7 percent.
Table 8-6 lists the compounds that were identified in only one of the
duplicate sample analyses. Except for three cases, the concentration was
below 1.0 ppbv for the compound identified in only one duplicate sample
analysis. It may be argued that some of the identifications were false
positives, but such an hypothesis is not reasonable for cases in which the
concentration was greater than 1.0 ppbv. In the case of 1,1,2,2-tetrachloro-
ethane, a concentration of 3.58 ppbv was verified on the chromatographic
traces for one of the duplicates, and was completely absent on the traces foi
the other duplicate.

8.7.4 GC/MS Confirmation Results
Based on twelve GC/MS analyses of the 3-hour air toxics samples, one frorr
each site location (except CLOH), the following results were obtained. The
GC/MS analyses confirmed 82.61% of the GC/MD analyses. The results are
summarized in Table 8-7, showing 19.63% positive GC/MD-positive GC/MS confir-
mation, 1.99% positive GC/MD-negative GC/MS confirmation, 15.40% negative
GC/MD-positive GC/MS comparisons, and 62.48% negative GC/MD-negative GC/MS
comparisons. The total confirmations, i.e., positive GC/MD-positive GC/MS
results plus negative GC/MD-negative GC/MS results, are significantly lower
than the confirmation percentages in the UATMP program, which are closer to
90% confirmations of GC/MD by GC/MS.
The reason that the percent confirmations are significantly lower is
because the negative GC/MD-positive GC/MS confirmations are so high (15.4%).
This indicates that the GC/MS identified a number of compounds that the GC/MD
did not identify. Past experience has shown that the negative GC/MD-positive
GC/MS identifications are typically twice the positive GC/MD-negative GC/MS
identifications. In this case the negative GC/MD-positive GC/MS identifica-
tions are almost eight times the positive GC/MD-negative GC/MS identifica-
tions.
Review of the analysis schedule for the GC/MD and the GC/MS points to
dynamic phenomena occurring in the canister. The canisters were analyzed by
GC/MD 16 to 24 hours after the canister pressures were reduced to atmospheric
pressure. The GC/MS analyses were performed at least 2 weeks after the GC/MD
analyses. At the time of the GC/MD analyses, the equilibrium adsorption
between the target compounds and the interior canister solid surfaces may not
have been reached. Thus many of the compounds that were identified in the
GC/MS analyses were apparently stvll in the adsorbed state on the canister
walls when the GC/MD analysis was performed.
After two weeks (between the GC/MD and GC/MS analyses), the adsorption
equilibrium had shifted and many more compounds had desorbed into the gas
phase and were identified by the GC/MS analyses. These findings indicate the
importance of ensuring that equilibrium occurs in the canisters before a
sample is withdrawn for any analysis. This equilibration is especially
important when the concentrations of the target compounds are in the ppbv
range.

8.7.5 External Audits
Monthly external audits were conducted for the 3-hour air toxics and
UATMP by the EPA-QAD. Audit No. 6, performed during the 3-hour air toxics
o
analysis period, results are reported in Table 8-8 and show -17 to +22%
bias, averaging 8.6% bias, for the GC/MD analyses and -44 to +8% bias,
averaging -18.4% bias, for the GC/MS analyses. These are excellent results
for the GC/MD analytical procedure since that instrument was to be used for
primary quantification in the UATMP. The GC/MS analyses are done primarily
for compound identification confirmation of the GC/MD identification.
8.8 DATA RECORDS
Data records for the 3-hour air toxics samples include:
t NMOC concentration of the sample;
• Total area counts of the GC/MD-FID response;
• Copies of the gas chromatographic trace for FID, PID, and ECD;
• Response data on Bernoulli disk;
t Response time for each compound; and
• Area counts for each detector.
In addition, notebooks have recorded calibration factors for each day,
Radian ID numbers for each sample, etc.

9.0 RECOMMENDATIONS, THREE-HOUR AIR TOXICS PROGRAM
The following recommendations derive from the 3-hour Air Toxics
Monitoring Program. The studies (Sections 9.1, 9.2, and 9.3) are directed
toward areas in which additional information is needed to validate further the
air toxics results. The final two suggestions (Sections 9.4 and 9.5) are
designed to give additional information useful to the project without
increasing the overall number of analyses.
9.1 COMPOUND STABILITY STUDIES
Compound stability in this context refers to whether the apparent
concentration of a compound in a sample taken from a canister is changing over
time. The apparent change in concentration may result from a chemical
reaction of the compound while in the canister, or result from a change in the
gas phase concentration resulting from adsorption of the compound on the
interior canister surfaces.
A study needed to investigate this phenomenon would take several
canisters, at least three from each initial concentration, ranging in target
compound concentration from zero to 20 ppbv. The canisters would be analyzed
24 hours after mixing, 72 hours after mixing, 30 days after mixing, and
60 days after mixing to determine any concentration changes. It is also
recommended that the same concentrations be mixed in canisters, but that
equilibration times of 7 days and 30 days be assigned before the first samples
are drawn from the canisters to determine the effect of equilibration time on
the concentration samples withdrawn from the canisters.
9.2 CANISTER CLEANUP STUDIES
For those canisters used for samples on which GC/MD analyses are
performed, the present canister cleanup procedure may be insufficient to
prevent significant carryover of target compounds from one sample to the next.
-------
A study needs to be conducted to determine if additional
pressurization/vacuum cycles, higher vacuum during the vacuum cycles, more
equilibration time during the steps of the cleanup cycle, or higher
temperature during canister cleanup are needed to prevent significant
carryover of target compounds from one ambient air sample to the next.
The present canister cleanup procedure is described in Section 3.3.2 and
consists of two vacuum/pressurization cycles with cleaned, dried air that has
been humidified. These cycles are followed by a final vacuum step to 5 mm Hg
vacuum. Preliminary measurements have indicated that after this cleaning
procedure has been completed, there may be sufficient organic compounds still
adsorbed on the canister interior surfaces to be desorbed and measured in the
0.05 to 0.50 ppbv range.
9.3 SAMPLER CERTIFICATION STUDIES
Certification of all samplers used to collect ambient air samples on
which GC/MD analyses are to be performed is recommended. This certification
would ensure that the sampler is not changing the actual organic compound
concentration of the ambient air being sampled, either by adding or removing
target compounds.
9.4 QUALITATIVE GC/MS FULL SCAN FOR COMPOUND IDENTIFICATION
It is recommended that when performing compound identification
confirmation studies by GC/MS, operation be in the full scan mode. This
practice makes it possible to identify compounds which may be interfering with
the target compounds. Full scan operation would reduce the sensitivity of the
GC/MS measurements, and increase the GC/MS detection limits, but the GC/MS
analyses are used in this study for purposes of compound identification
confirmation, and the sensitivity is not a critical factor for this
measurement.
9.5 REPLICATE AND DUPLICATE ANALYSES
In future studies, replicate analyses on the duplicate samples are
recommended. In this way it would be possible to separate sampling precision
from analytical precision.

METHOD FOR THE DETERMINATION OF NON-METHANE ORGANIC COMPOUNDS (NMOC)
IN AMBIENT AIR USING CRYOGENIC PRECONCENTRATION AND DIRECT FLAME
IONIZATION DETECTION (PDFID)
1. Scope
1.1 In recent years, the relationship between ambient concentrations
of precursor organic compounds and subsequent downwind concentra-
tions of ozone has been described by a variety of photochemical
dispersion models. The most Important application of such models
1s to determine the degree of control of precursor organic com-
pounds that 1s necessary 1n an urban area to achieve compliance
with applicable ambient air quality standards for ozone (1,2).
1.2 The more elaborate theoretical models generally require detailed
organic species data obtained by multlconponent gas chromatograpf
The Empirical Kinetic Modeling Approach (EKMA), however, requires
only the total non-methane organic compound (NMOC) concentration
data; specifically, the average total NMOC concentration from 6
a.m. to 9 a.m. dally at the sampling location. The use of total
NMOC concentration data 1n the EKMA substantially reduces the
cost and complexity of the sampling and analysis system by not
requiring qualitative and quantitative species Identification.
1.3 Method T01, "Method for The Determination of Volatile Organic
Compounds 1n Ambient A1r Using Tenax* Adsorption and Gas
Chromatography/Mass Spectrometry (GC/MS)", employs collection
of certain volatile organic compounds on Tenax* GC with subse-
quent analysis by thermal desorptlon/cryogenlc preconcentration
and GC/MS Identification. This method (T012) combines the same
type of cryogenic concentration technique used in Method T01
for high sensitivity with the simple flame ionization detector
(FID) of the GC for total NMOC measurements, without the GC
columns and complex procedures necessary for species separation.
-------
T012-2
1.4 In a flame ionization detector, the sample is Injected into a
hydrogen-rich flame where the organic vapors burn producing
Ionized molecular fragments. The resulting 1on fragments are
then collected and detected. The FID is nearly a universal
detector. However, the detector response varies with the specie
of [functional group in] the organic compound in an oxygen atmos
phere. Because this method employs a helium or argon carrier
gas. the detector response is nearly one for all compounds.
Thus, the historical short-coming of the FID involving varying
detector response to different organic functional groups is
minimized.
1.5 The method can be used either for direct, in situ ambient
measurements or (more commonly) for analysis of Integrated
samples collected in specially treated stainless steel canisters
EKMA models generally require 3-hour Integrated NMOC measurement
over the 6 a.m. to 9 a.m. period and are used by State or local
agencies to prepare State Implementation Plans (SIPs) for ozone
control to achieve compliance with the National Ambient Air
Quality Standards (NAAQS) for ozone. For direct, 1n situ amblei
measurements, the analyst must be present during the 6 a.m. to
9 ajn. period, and repeat measurements (approximately six per
hour) must be taken to obtain the 6 a.m. to 9 a.m. average
NMOC concentration. The use of sample canisters allows the
collection of Integrated air samples over the 6 a.m. to 9 a.m.
period by unattended, automated samplers. This method has
Incorporated both sampling approaches.

3. Summary of Method
3.1 A whole air sample 1s either extracted directly from the ambient
air and analyzed on site by the GC system or collected Into a
precleaned sample canister and analyzed off site.
3.2 The analysis requires drawing a fixed-volume portion of the
sample air at a low flow rate through a glass-bead filled trap
that 1s cooled to approximately -186°C with liquid argon. The
cryogenic trap simultaneously collects and concentrates the
NMOC (either via condensation or adsorption) while allowing
the methane, nitrogen, oxygen, etc. to pass through the trap
without retention. The system 1s dynamically calibrated so
that the volume of sample passing through the trap does not
have to be quantitatively measured, but must be precisely
repeatable between the calibration and the analytical phases.
3.3 After the fixed-volume air sample has been drawn through the
trap, a helium carrier gas flow 1s diverted to pass through
the trap, 1n the opposite direction to the sample flow, and
Into an FID. When the residual air and methane have been
flushed from the trap and the FID baseline restabllizes,
the cryogen 1s removed and the temperature of the trap 1s
raised to approximately 90°C.
3.4 The organic compounds previously collected 1n the trap revol-
atllize due to the Increase 1n temperature and are carried Into
the FID, resulting in a response peak or peaks from the FID.
The area of the peak or peaks 1s Integrated, and the Integrated
value 1s translated to concentration units via a previously-
obtained calibration curve relating Integrated peak areas with
known concentrations of propane.
3.5 By convention, concentrations of NMOC are reported 1n units of
parts per million carbon (ppmC), which, for a specific compound
1s the concentration by volume (ppmV) multiplied by the number
of carbon atoms 1n the compound.
-------
T012-4
3.6 The cryogenic trap simultaneously concentrates the NMOC while
separating and removing the methane from air samples. The
technique is thus direct reading for NMOC and, because of
the concentration step, 1s more sensitive than conventional
continuous NMOC analyzers.
4. Significance
4.1 .Accurate measurements of ambient concentrations of NMOC
are Important for the control of photochemical smog because
these organic compounds are primary precursors of atmospheric
ozone and other oxidants. Achieving and maintaining compliance
with the NAAQS for ozone thus depends largely on control of
ambient levels of NMOC.
4.2 The NMOC concentrations typically found at urban sites may
range up to 5-7 ppmC or higher. In order to determine transport
of precursors Into an area, measurement of NMOC upwind of the
area may be necessary. Upwind NMOC concentrations are likely
to be less than a few tenths of 1 ppm.
4.3 Conventional methods that depend on gas chromatography and
qualitative and quantitative species evaluation are excessively
difficult and expensive to operate and maintain when speciated
measurements are not needed. The method described here Involve:
a simple, cryogenic preconcentration procedure with subsequent,
direct, flame 1on1zat1on detection. The method 1s sensitive an
provides accurate measurements of ambient NMOC concentrations
where speciated data are not required as applicable to the
EKMA.

zero pressure (as opposed to atmospheric pressure), usually ex-
Pressed as pounds-force per square inch absolute (psia).
5.2 Cryogen - A substance used to obtain very low trap temperatures

6. Interferences
6.1 In field and laboratory evaluation, water was found to cause a
positive shift 1n the FID baseline. The effect of this shift
1s minimized by carefully selecting the Integration termination
point and adjusted baseline used for calculating the area of
the NMOC peak(s).
6.2 When using helium as a carrier gas, FID response 1s quite
uniform for most hydrocarbon compounds, but the response can
vary considerably for other types of organic compounds.
7. Apparatus
7.1 Direct Air Sampling (Figure 1)
7.1.1 Sample manifold or sample inlet line - to bring
sample air Into the analytical system.
7.1.2 Vacuum pump or blower - to draw sample air through a
sample manifold or long Inlet line to reduce inlet
residence time. Maximum residence time should be no
greater than 1 minute.
7.2 Remote Sample Collection 1n Pressurized Canisters (Figure 2)
*
7.2.1 Sample canister(s) - stainless steel, Summa*-pol1shed
vessel(s) of 4-6 L capacity (Scientific Instrumentation
Specialists,. Inc., P.O. Box 8941, Moscow. ID 83843), used
for automatic collection of 3-hour integrated field
air samples. Each canister should have a unique identi-
fication number stamped on Its frame.
7.2.2 Sample pump - stainless steel, metal bellows type
(Model MB-151, Metal Bellows Corp., 1075 Providence
Highway, Sharon, MA 02067) capable of 2 atmospheres
minimum output pressure. Pump must be free of leaks,
clean, and uncontaminated by oil or organic compounds.
7.2.3 Pressure gauge - 0-30 pslg (0-240 kPa).
7.2.4 Solenoid valve - special electrically-operated, bistable
solenoid valve (Skinner Magnelatch Valve, New Britain*
-------
T012-7
CT), to control sample flow to the canister with negligi-
ble temperature rise (Figure 3). The use of the Skinner
Magnelatch valve avoids any substantial temperature rise
that would occur with a conventional, normally closed
solenoid valve, which would have to be energized during
the entire sample period. This temperature rise in the
valve could cause outgasing of organics from the Viton
valve seat material. The Skinner Magnelatch valve
requires only a brief electrical pulse to open or close
at the appropriate start and stop times and therefore
experiences no temperature increase. The pulses may
be obtained with an electronic timer that can be pro-
grammed for short (5 to 60 seconds) OH periods or with
a conventional mechanical timer and a special pulse
circuit. Figure 3 [a] Illustrates a simple electrical
pulse circuit for operating the Skinner Magnelatch
solenoid valve with a conventional mechanical timer.
However, with this simple circuit, the valve may
operate unpredlctably during brief power Interruptions
or 1f the timer Is manually switched on and off too
fast. A better circuit Incorporating a time-delay
relay to provide more reliable valve operation 1s
shown 1n Figure 3[b].
7.2.5 Stainless steel orifice (or short capillary) - capable
of maintaining a substantially constant flow over the
sampling period (see Figure 4).
7.2.6 Particulate matter filter - 2 micron stainless steel
sintered In-line type (see Figure 4).
7.2.7 Timer - used for unattended sample collection. Capable
of controlling pump(s) and solenoid valve.
7.3 Sample Canister Cleaning (Figure 5)
7.3.1 Vacuum pump - capable of evacuating sample canister(s)
to an absolute pressure of <5 mm Hg.
7.3.2 Manifold - stainless steel manifold with connections
for simultaneously cleaning several canisters.
7.3.3 Shut off valve(s) - seven required.
7.3.4 Vacuum gauge - capable of measuring vacuum in the manift
to an absolute pressure of 5 mm Hg or less.
-------
T012-8
7.3.5 Cryogenic trap (2 required) - U-shaped open tubular trap
cooled with liquid nitrogen or argon used to prevent con-
tamination from back diffusion of oil from vacuum pump,
and to provide clean, zero air to sample canister(s).
7.3.6 Pressure gauge - 0-50 pslg (0-345 kPa), to monitor
zero air pressure.
7.3.7 Flow control valve - to regulate flow of zero air into
canlster(s).
7.3.8 Humidifier - water bubbler or other system capable of
providing moisture to the zero air supply.
7.4 Analytical System (Figure 1)
7.4.1 FID detector system - Including flow controls for the
FID fuel and air, temperature control for the FID, and
signal processing electronics. The FID burner air,
hydrogen, and helium carrier flow rates should be set
according to the manufacturer's Instructions to obtain an
adequate FID response while maintaining as stable a flame
as possible throughout all phases of the analytical cycle
7.4.2 Chart recorder - compatible with the FID output signal,
to record FID response.
7.4.3 Electronic Integrator - capable of Integrating the area
of one or more FID response peaks and calculating peak
area corrected for baseline drift. If a separate Inte-
grator and chart recorder are used, care must be exer-
cised to be sure that these components do not Interfere
with each other electrically. Range selector controls
on both the Integrator and the FID analyzer may not pro-
vide accurate range ratios, so Individual calibration
curves should be prepared for each range to be used.
The Integrator should be capable of marking the beginnir
and ending of peaks, constructing the appropriate base-
line between the start and end of the Integration perioc
and calculating the peak area.
-------
T012-9
Note: The FID (7.4.1), chart recorder (7.4.2), inte-
grator (7.4.3), valve heater (7.4.5), and a trap heat-
Ing system are conveniently provided by a standard lab-
oratory chromatograph and associated integrator. EPA
has adapted two such systems for the PDFID method: a
Hewlett-Packard model 5880 (Hewlett-Packard Corp., Avon-
dale, PA) and a Shimadzu model GC8APF (Shimadzu Scientif-
Instruments Inc., Columbia, MO; see Reference 5). Other
similar systems may also be applicable.
7.4.4 Trap - the trap should be carefully constructed from a
single piece of chromatographic-grade stainless steel
tubing (0.32 on O.D, 0.21 cm I.D.) as s"hown in Figure 6.
The central portion of the trap (7-10 cm) is packed with
60/80 mesh glass beads, with small glass wool (dimethyld
chlorosilane-treated) plugs to retain the beads. The
trap must fit conveniently into the Dewar flask (7.4.9),
and the arms must be of an appropriate length to allow
the beaded portion of the trap to be submerged below
the level of liquid cryogen in the Dewar. The trap shou
connect directly to the six-port valve, if possible,
to minimize line length between the trap and the FID. T
trap must be mounted to allow the Dewar to be slipped
conveniently on and off the trap and also to facilitate
heating of the trap (see 7.4.13).
7.4.5 Six-port chromatographic valve - Seiscor Model VIII
(Seismograph Service Corp., Tulsa, OK), Valco Model 911C
(Valco Instruments Co., Houston, TX), or equivalent.
The six-port valve and as much of the interconnecting
tubing as practical should be located Inside an oven or
otherwise heated to 80 - 90°C to minimize wall losses

lines should be as short as practical.

7.5 Commercially Available PDFID System (5)
7.5.1 A convenient and cost-effective modular PDFID system suit
able for use with a conventional laboratory chromatograph
1s commercially available (NuTech Corporation, Model 8548
2806 Cheek Road. Durham, NC, 27704, (919) 682-0402).
7.5.2 This modular system contains almost all of the apparatus
Items needed to convert the chromatograph into a PDFID
analytical system and has been designed to be readily
available and easy to assemble.
8. Reagents and Materials
8.1 Gas cylinders of helium and hydrogen - ultrahlgh purity grade.
8.2 Combustion air - cylinder containing less than 0.02 ppm hydro-
carbons, or equivalent air source.
8.3 Propane calibration standard - cylinder containing 1-100 ppm
(3-300 ppmC) propane 1n air. The cylinder assay should be
traceable to a National Bureau of Standards (NBS) Standard Refer
ence Material (SRM) or to a NBS/EPA-approved Certified Reference
Material (CRM).
8.4 Zero air - cylinder containing less than 0.02 ppmC hydrocar-
bons. Zero air may be obtained from a cylinder of zero-grade
compressed air scrubbed with Drier-He* or silica gel and 5A
molecular sieve or activated charcoal, or by catalytic cleanup
-------
T012-12
of ambient air. All zero air should be passed through a liquid
argon cold trap for final cleanup, then passed through a hyrdo-
carbon-free water bubbler (or other device) for humidification.
8.5 Liquid cryogen - liquid argon (bp -185.7°C) or liquid oxygen,
(bp -183°C) may be used as the cryogen. Experiments have shown
no differences in trapping efficiency between liquid argon and
liquid oxygen. However, appropriate safety precautions must be
taken if liquid oxygen 1s used. Liquid nitrogen (bp -195°C)
should not be used because it causes condensation of oxygen and
methane 1n the trap.
9. Direct Sampling
9.1- For direct ambient air sampling, the cryogenic trapping system
draws the air sample directly from a pump-ventilated distributioi
manifold or sample line (see Figure 1). The connecting line sho
be of small diameter (1/8" 0.0.) stainless steel tubing and as
short as possible to minimize Its dead volume.
. 9.2 Multiple analyses over the sampling period must be made to estab
Hsh hourly or 3-hour NMOC concentration averages.
10. Sample Collection 1n Pressurized Canlster(s)
•
For Integrated pressurized canister sampling, ambient air 1s sampled
by a metal bellows pump through a critical orifice (to maintain
constant flow), and pressurized Into a clean, evacuated, Summa*-
pollshed sample canister. The critical orifice size Is chosen so
that the canister 1s pressurized to approximately one atmosphere abo<
ambient pressure, at a constant flow rate over the desired sample
period. Two canisters are connected 1n parallel for duplicate sampl
The canister(s) are then returned to the laboratory for analysis,
using the PDFIO analytical system. Collection of ambient air sample
in pressurized canisters provides the following advantages:
o Convenient Integration of ambient samples over a specific
time period
o Capability of remote sampling with subsequent central
laboratory analysis
o Ability to ship and store samples, 1f necessary
-------
T012-13
o Unattended sample collection
o Analysis of samples from multiple sites with one analytical
system
o Collection of replicate samples for assessment of measurement
precision
With canister sampling, however, great care must be exercised in
selecting, cleaning, and handling the sample canister(s) and sampling
apparatus to avoid losses or contamination of the samples.
10.1 Canister Cleanup and Preparation
10.1.1 All canisters must be clean and free of any contaminants
before sample collection.
10.1.2 Leak test all canisters by pressurizing them to approxi-
mately 30 psig [200 kPa (gauge)] with zero air. The
use of the canister cleaning system (see Figure 5) may
be adequate for this task. Measure the final pressure •
close the canister valve, then check the pressure after
24 hours. If leak tight, the pressure should not vary
more than +_2 psig over the 24-hour period. Note leak
check result on sampling data sheet, Figure 7.
10.1.3 Assemble a canister cleaning system, as Illustrated in
Figure 5. Add cryogen to both the vacuum pump and zero
air supply traps. Connect the canister(s) to the mani-
fold. Open the vent shut off valve and the canister
valve(s) to release any remaining pressure in the canis-
ter. Now close the vent shut off valve and open the
vacuum shut off valve. Start the vacuum pump and evacua
the canlster(s) to £ 5.0 mm Hg (for at least one hour).
[Note: On a daily basis or more often if necessary, blow
out the cryogenic traps with zero air to remove any
trapped water from previous canister cleaning cycles.]
10.1.4 Close the vacuum and vacuum gauge shut off valves and
open the zero air shut off valve to pressurize the canis
ter(s) with moist zero air to approximately 30 psig [200
kPa (gauge)]. If a zero gas generator system is used,
-------
T012-14
the flow rate may need to be limited to maintain the
zero air quality.
10.1.5 Close the zero shut off valve and allow canister(s) to
vent down to atmospheric pressure through the vent shut
off valve. Close the vent shut off valve. Repeat steps
10.1.3 through 10.1.5 two additional times for a total 01
three (3) evacuation/pressurization cycles for each set t
canisters.
10.1.6 As a "blank" check of the canister(s) and cleanup proce-
dure, analyze the final zero-air fill of 100% of the
canisters until the cleanup system and canisters are
proven reliable. ' The check can then be reduced to a
lower percentage of canisters. Any canister that does
not test clean (compared to direct analysis of humidifie<
zero air of less than 0.02 ppmC) should not be utilized.
10.1.7 The canister is then re-evacuated to £ 5.0 mm Hg, using
the canister cleaning system, and remains in this con-
dition until use. Close the canister valve, remove the
canister from the canister cleaning system and cap
canister connection with a stainless steel fitting. The
canister 1s now ready for collection of an air sample.
Attach an Identification tag to the neck of each
canister for field notes and chain-of-custody purposes.
10.2 Collection of Integrated Whole-Air Samples
10.2.1 Assemble the sampling apparatus as shown in Figure 2.
The connecting lines between the sample pump and the
canister(s) should be as short as possible to minimize
their volume. A second canister 1s used when a duplicai
sample 1s desired for quality assurance (QA) purposes
(see Section 12.2.4). The small auxiliary vacuum pump
purges the inlet manifold or lines with a flow of
several L/min to minimize the sample residence time.
The larger metal bellows pump takes a small portion of
this sample to fill and pressurize the sample canister(
Both pumps should be shock-mounted to minimize vibratio
Prior to field use, each sampling system should be leak
-------
T012-15
tested. The outlet side of the metal bellows pump can
be checked for leaks by attaching the 0-30 psig pressure
gauge to the canister (s) Inlet via connecting tubing and
pressurizing to 2 atmospheres or approximately 29.4 psig.
If pump and connecting lines are leak free pressure should
remain at +2 psig for 15 minutes. To check the Inlet
slde» plug the sample Inlet and Insure that there 1s no
flow at the outlet of the pump.
10.2.2 Calculate the flow rate needed so that the canister (s)
are pressurized to approximately one atmosphere above
ambient pressure (2 atmospheres absolute pressure)
over the desired sample period, utilizing the following
equation:
(T(60)
where:
F « flow rate (cra3/m1n)
P « final canister pressure (atmospheres absolute)
- (Pg/Pa) + 1
V » volume of the canister (cm3)
N « number of canisters connected together for
simultaneous sample collection
T « sample period (hours)
Pg » gauge pressure 1n canister, psig (kPa)
Pa « standard atmospheric pressure, 14.7 psig (101 kPa
For example* 1f one 6-L canister 1s to be filled to 2
atmospheres absolute pressure (14.7 psig) 1n 3 hours,
the flow rate would be calculated as follows:
F « 2 x 6000 x 1 * 67 cm^/mln
3 x 60
10.2.3 Select a critical orifice or hypodermic needle suitable
to maintain a substantially constant flow at the cal-
culated flow rate Into the canister (s) over the desired
sample period. A 30-gauge hypodermic needle, 2.5 cm
-------
T012-16
long, provides a flow of approximately 65 cm3/min with
the Metal Bellows Model MBV-151 pump (see Figure 4).
Such a needle will maintain approximately constant flow
up to a canister pressure of about 10 pslg (71 kPa),
after which the flow drops with Increasing pressure.
At 14.7 psig (2 atmospheres absolute pressure), the
flow 1s about 10% below the original flow.
'10.2.4 Assemble the 2.0 micron stainless steel In-line particu-
late filter and position 1t 1n front of the critical
orifice. A suggested filter-hypodermic needle assembly
can be fabricated as Illustrated 1n Figure 4.
10.2.5 Check the sampling system for contamination by filling
two evacuated, cleaned canister(s) (See Section 10.1)
with humidified zero air through the sampling system.
Analyze the canisters according to Section 11.4. The
sampling system Is free of contamination if the canister
contain less than 0.02 ppraC hydrocarbons, similar to
that of humidified zero air.
10.2.6 During the system contamination check procedure, check
the critical orifice flow rate on the sampling system
to Insure that sample flow rate remains relatively con-
stant (+10%) up to about 2 atmospheres absolute pressure
(101 kPa). Note: A drop 1n the flow rate may occur
near the end of the sampling period as the canister
pressure approaches two atmospheres.
10.2.7 Reassemble the sampling system. If the Inlet sample 11n
1s longer than 3 meters, Install an auxiliary pump to
ventilate the sample line, as Illustrated in Figure 2.
10.2.8 Verify that the timer, pump(s) and solenoid valve are
connected and operating properly.
10.2.9 Verify that the timer 1s correctly set for the desired
sample period, and that the solenoid valve 1s closed.
10.2.10 Connect a cleaned, evacuated canister(s) (Section 10.1)
to the non-contaminated sampling system, by way of the
solenoid valve, for sample collection.
-------
T012-17
10.2.11 Make sure the solenoid valve is closed. Open the
canister valve(s). Temporarily connect a small rotamete
to the sample Inlet to verify that there 1s no flow.
Note: Flow detection would Indicate a leaking (or open,
solenoid valve. Remove the rotameter after leak de-
tection procedure.
10.2.12 Fill out the necessary information on the Field Data
Sheet (Figure 7).
10.2.13 Set the automatic timer to start and stop the pump
or pumps to open and close the solenoid valve at the
appropriate time for the Intended sample period.
Sampling will begin at the pre-determined time.
10.2.14 After the sample period, close the canister valve(s) an
disconnect the canister(s) from the sampling system.
Connect a pressure gauge to the canlster(s) and briefly
open and close the canister valve. Note the canister
pressure on the Field Data Sheet (see Figure 7). The
canister pressure should be approximately 2 atmospheres
absolute [1 atmosphere or 101 kPa (gauge)]. Note: If
the canister pressure 1s not approximately 2 atmosphere
absolute (14.7 pslg), determine and correct the cause t
fore next sample. Re-cap canister valve.
10.2.15 Fill out the Identification tag on the sample canister(
and complete the Field Data Sheet as necessary. Note
any activities or special conditions 1n the area (rain
smoke, etc.) that may affect the sample contents on th
sampling data sheet.
10.2.16 Return the canlster(s) to the analytical system for
analysis.
11. Sample Analysis
11.1 Analytical System Leak Check
11.1.1 Before sample analysis, the analytical system 1s as sen
(see Figure 1) and leak checked.
-------
T012-18
11.1.2 To leak check the analytical system, place the six-por
gas valve In the trapping position. Disconnect and ca;
the absolute pressure gauge. Insert a pressure gauge
capable of recording up to 60 pslg at the vacuum valve
outlet.
11.1.3 Attach a valve and a zero air supply to the sample
Inlet port. Pressurize the system to about 50 psig
(350 kPa) and close the valve.
11.1.4 Walt approximately 3 hrs. and re-check pressure. If
the pressure did not vary more than +_ 2 psig, the
system 1s considered leak tight.
11.1.5 If the system 1s leak free, de-pressurize and reconnec
absolute pressure gauge.
11.1.6 The analytical system leak check procedure needs to
be performed during the system checkout, during a sen
of analysis or 1f leaks are suspected. This should b<
part of the user-prepared SOP manual (see Section 12.:
11.2 Sample Volume Determination
11.2.1 The vacuum reservoir and absolute pressure gauge are
used to meter a precisely repeatable volume of sample
air through the cryogenlcally-cooled trap, as follows
With the sample valve closed and the vacuum valve ope
the reservoir 1s first evacuated with the vacuum pump
to a predetermined pressure (e.g., 100 mm Hg). Then
the vacuum valve 1s closed and the sample valve 1s
opened to allow sample air to be drawn through the
cryogenic trap and Into the evacuated reservoir until
a second predetermined reservoir pressure 1s reached
(e.g., 300 mn Hg). The (fixed) volume of air thus
sampled 1s determined by the pressure rise 1n the
vacuum reservoir (difference between the predetermln*
pressures) as measured by the absolute pressure gaug
(see Section 12.2.1).
-------
T012-19
11.2.2 The sample volume can be calculated by:
V
s IPS
where:
Vs » volume of air sampled (standard on3)
AP » pressure difference measured by gauge (mm H<
Vr - volume of vacuum reservoir (cm )
usually 1 L
Ps « standard pressure (760 mm Hg)
For example, with a vacuum reservoir of 1000 cm3 and a
pressure change of 200 mm Hg (100 'to 300 mm Hg), the volui
sampled would be 263 cm3. [Note: Typical sample volume
using this procedure 1s between 200-300 cm3.]
11.2.3 The sample volume determination need only be performed on
during the system check-out and shall be part of the
user-prepared SOP Manual (see Section 12.1).
11.3 Analytical System Dynamic Calibration
11.3.1 Before sample analysis, a complete dynamic calibration
of the analytical system should be carried out at five or
more concentrations on each range to define the calibra-
tion curve. This should be carried out Initially and
periodically thereafter [may be done only once during
a series of analyses]. This should be part of the
user-prepared SOP Manual (See Section 12.1). The
calibration should be verified with two or three-point
calibration checks (Including zero) each day the analyt-
ical system 1s used to analyze samples.
11.3.2 Concentration standards of propane are used to calibrate
the analytical system. Propane calibration standards
may be obtained directly from low concentration cylinder
standards or by dilution of high concentration cylinder
-------
T012-20
standards with zero air (see Section 8.3). Dilution
flow rates must be measured accurately, and the combined
gas stream must be mixed thoroughly for successful cali-
bration of the analyzer. Calibration standards should
be sampled directly from a vented manifold or tee. Note:
Remember that a propane NMOC concentration in ppmC is
three times the volumetric concentration in ppm.
11.3.3 Select one or more combinations of the following parameter
to provide the desired range or ranges (e.g., 0-1.0 ppmC
or 0-5.0 ppmC): FID attenuator setting, output voltage
setting, integrator resolution (if applicable), and sample
volume. Each individual range should be calibrated sep-
arately and should have a separate calibration curve.
Note: Modern GC Integrators may provide automatic ranging
such that several decades of concentration may be covered
in a single range. The user-prepared SOP manual should
address variations applicable to a specific system design
(see Section 12.1).
•
11.3.4 Analyze each calibration standard three times according
to the procedure in Section 11.4. Insure that flow
rates, pressure gauge start and stop readings, Initial
cryogen liquid level in the Dewar, timing, heating, inte-
grator settings, and other variables are the same as
those that will be used during analysis of ambient
samples. Typical flow rates for the gases are: hydrogen,
30 era3/minute; helium carrier, 30 on3/rainute; burner
air, 400 on3/minute.
11.3.5 Average the three analyses for each concentration standarc
and plot the calibration curve(s) as average Integrated pt
area reading versus concentration in ppmC. The relative
standard deviation for the three analyses should be less
-------
T012-21
than 3% (except for zero concentration). Linearity should
be expected; points that appear to deviate abnormally
should be repeated. Response has been shown to be linear
over a wide range (0-10,000 ppbC). If nonlinearity is
observed, an effort should be made to identify and correct
the problem. If the problem cannot be corrected, addi-
tional points in the nonlinear region may be needed to
define the calibration curve adequately.
11.4 Analysis Procedure
11.4.1 Insure the analytical system has been assembled properly,
leaked checked, and properly calibrated through a dynamic
standard calibration. Light the FID detector and allow to
stabilize.
11.4.2 Check and adjust the helium carrier pressure to provide th
correct carrier flow rate for the system. Helium is used
to purge residual air and methane from the trap at the
end of the sampling phase and to carry the re-volatilized
NMOC from the trap Into the FID. A single-stage auxiliary
regulator between the cylinder and the analyzer may not
be necessary, but Is recommended to regulate the helium
pressure better than the multistage cylinder regulator.
When an auxiliary regulator 1s used, the secondary stage
of the two-stage regulator must be set at a pressure
higher than the pressure setting of the single-stage
regulator. Also check the FID hydrogen and burner air
flow rates (see 11.3.4).
11.4.3 Close the sample valve and open the vacuum valve to
evacuate the vacuum reservoir to a specific predetermined
value (e.g., 100 mm Hg).
11.4.4 With the trap at room temperature, place the six-port
valve in the Inject position.
11.4.5 Open the sample valve and adjust the sample flow rate
needle valve for an appropriate trap flow of 50-100
cra3/min. Note: The flow will be lower later, when the
trap Is cold.
-------
T012-22
11.4.6 Check the sample canister pressure before attaching it
to the analytical system and record on Field Data
Sheet (see Figure 7). Connect the sample canister or
direct sample Inlet to the six-port valve, as shown in
Figure 1. For a canister* either the canister valve
or an optional fine needle valve Installed between the
canister and the vent 1s used to adjust the canister
flow rate to a value slightly higher than the trap
flow rate set by the sample flow rate needle valve.
The excess flow exhausts through the vent, which
assures that the sample air flowing through the trap
1s at atmospheric pressure. The vent 1s connected to
a flow Indicator such as a rotameter as an indication of
vent flow to assist 1n adjusting the flow control
valve. Open the canister valve and adjust the canister
valve or the sample flow needle valve to obtain a
moderate vent flow as Indicated by the rotameter. The
sample flow rate will be lower (and hence the vent
flow rate will be higher) when the the trap 1s cold.
11.4.7 Close the sample valve and open the vacuum valve (If
.not already open) to evacuate the vacuum reservoir.
With the six-port valve 1n the Inject position and the
vacuum valve open, open the sample valve for 2*3 minutes
[with both valves open, the pressure reading won't
change] to flush and condition the Inlet lines.
11.4.8 Close the sample valve and evacuate the reservoir to
the predetermined sample starting pressure (typically
100 mm Hg) as Indicated by the absolute pressure gauge.
11.4.9 Switch the six-port valve to the sample position.
11.4.10 Submerge the trap 1n the cryogen. Allow a few minutes
for the trap to cool completely (Indicated when the
cryogen stops boiling). Add cryogen to the Initial
level used during system dynamic calibration. The level
of the cryogenic liquid should remain constant with
respect to the trap and should completely cover the
beaded portion of the trap.
-------
T012-23
11.4.11 Open the sample valve and observe the increasing pressure
on the pressure gauge. When it reaches the specific pre-
determined pressure (typically 300 mm Hg) representative
of the desired sample volume (Section 11.2), close the
sample valve.
11.4.12 Add a little cryogen or elevate the Dewar to raise the
liquid level to a point slightly higher (3-15 mm) than
the initial level at the beginning of the trapping.
Note: this Insures that organics do not bleed from the
trap and are counted as part of the NMOC peak(s).
11.4.13 Switch the 6-port valve to the Inject position, keeping
the cryogenic liquid on the trap until the methane and
upset peaks have deminished (10-20 seconds). Now close
the canister valve to conserve the remaining sample in
the canister.
11.4.14 Start the Integrator and remove the Dewar flask containing
the cryogenic liquid from the trap.
11.4.15 Close the GC oven door and allow the GC oven (or alter-
nate trap heating system) to heat the trap at a predeter-
mined rate (typically, 30°C/ra1n) to 90°. Heating the traf
volatilizes the concentrated NMOC such that the FID pro-
duces Integrated peaks. A uniform trap temperature rise
rate (above 0°C) helps to reduce variability and facili-
tates more accurate correction for the moisture-shifted
baseline. With a chromatograph oven to heat the trap,
the following parameters have been found to be acceptable
Initial temperature, 30°C; Initial time, 0.20 minutes
(following start of the Integrator); heat rate, 30°/minut(
final temperature, 90°C.
11.4.16 Use the same heating process and temperatures for both
calibration and sample analysis. Heating the trap too
quickly may cause an Initial negative response that
could hamper accurate Integration. Some Initial exper-
imentation may be necessary to determine the optimal
heating procedure for each system. Once established,
the procedure should be consistent for each analysis
as outlined in the user-prepared SOP Manual.
-------
T012-24
11.4.17 Continue the integration (generally, in the range of
1-2 minutes is adequate) only long enough to include
all of the organic compound peaks and to establish the
end point FID baseline, as illustrated in Figure 8.
The integrator should be capable of marking the begin-
ning and ending of peaks, constructing the appropriate
operational baseline between the start and end of the
integration period, and calculating the resulting
corrected peak area. This ability is necessary because
the moisture in the sample, which is also concentrated
in the trap, will cause a slight positive baseline
shift. This baseline shift starts as the trap warms
and continues until all of the moisture 1s swept from
the trap, at which time the baseline returns to Its
normal level. The shift always continues longer than
the ambient organic peak(s). The integrator should be
programmed to correct for this shifted baseline by
ending the Integration at a point after the last NMOC
peak and prior to the return of the shifted baseline to
normal (see Figure 8) so that the calculated operational
baseline effectively compensates for the water-shifted
baseline. Electronic Integrators either do this auto-
matically or they should be programmed to make this cor-
rection. Alternatively, analyses of humidified zero air
prior to sample analyses should be performed to determine
the water envelope and the proper blank value for
correcting the ambient air concentration measurements
accordingly. Heating and flushing of the trap should
continue after the Integration period has ended to
Insure all water has been removed to prevent buildup of
water 1n the trap. Therefore, be sure that the 6-port
valve remains in the Inject position until all moisture
has purged from the trap (3 minutes or longer).
-------
T012-25
11.4.18 Use the dynamic calibration curve (see Section 11.3)
to convert the integrated peak area reading into
concentration units (ppmC). Note that the NMOC peak
shape may not be precisely reproducible due to vari-
ations in heating the trap, but the total NMOC peak
area should be reproducible.
11.4.19 Analyze each canister sample at least twice and report
the average NMOC concentration. Problems during an
analysis occasionally will cause erratic or incon-
sistent results. If the first two analyses do not
agree within ^ 5% relative standard deviation (RSD),
additional analyses should be made to identify in-
accurate measurements and produce a more accurate
average (see also Section 12.2.)*
12. Performance Criteria and Quality Assurance
This section summarizes required quality assurance measures and pro-
vides guidance concerning performance criteria that should be achieved
. within each laboratory.
12.1 Standard Operating Procedures (SOPs)
12.1.1 Users should generate SOPs describing and documenting
the following activities in their laboratory: (1)
assembly, calibration, leak check, and operation of the
specific sampling system and equipment used; (2) prepara-
tion, storage, shipment, and handling of samples; (3)
assembly, leak-check, calibration, and operation of the
analytical system, addressing the specific equipment used;
(4) canister storage and cleaning; and (5) all aspects of
of data recording and processing, Including lists of
computer hardware and software used.
12.1.2 SOPs should provide specific stepwlse Instructions and
should be readily available to, and understood by, the
laboratory personnel conducting the work.
-------
T012-26
12.2 Method Sensitivity, Accuracy, Precision and Linearity
12.2.1 The sensitivity and precision of the method 1s proportional
to the sample volume. However, ice formation in the
trap may reduce or stop the sample flow during trapping
if the sample volume exceeds 500 cm3. Sample volumes
below about 100-150 cm3 may cause Increased measurement
variability due to dead volume in lines and valves. For
most typical ambient NMOC concentrations, sample volumes
in the range of 200-400 cm3 appear to be appropriate.
If a response peak obtained with a 400 cm3 sample is
off scale or exceeds the calibration range, a second
analysis can be carried out with a smaller volume. The
actual sample volume used need not be accurately known
if 1t is precisely repeatable during both calibration
and ana-lysis. Similarly, the actual volume of the
vacuum reservoir need not be accurately known. But the
reservoir volume should be matched to the pressure
range and resolution of the absolute pressure gauge so
that the measurement of the pressure change in the reser-
voir, hence the sample volume, 1s repeatable within 1%.
A 1000 era3 vacuum reservoir and a pressure change of
200 mm Hg, measured with the specified pressure gauge,
have provided a sampling precision of ± 1.31 cm3. A
smaller volume reservoir may be used with a greater
pressure change to accommodate absolute pressure gauges
with lower resolution, and vice versa.
12.2.2 Some FID detector systems associated with laboratory
chromatographs may have autoranglng. Others may
provide attenuator control and Internal full-scale
output voltage selectors. An appropriate combination
should be chosen so that an adequate output level for
accurate Integration 1s obtained down to the detection
limit; however, the electrometer or Integrator must not
be driven Into saturation at the upper end of the
calibration. Saturation of the electrometer may be
Indicated by flattening of the calibration curve at

high concentrations. Additional adjustments of range
and sensitivity can be provided by adjusting the sample
volume used, as discussed in Section 12.2.1.
12.2.3 System linearity has been documented (6) from 0 to 10,000
ppbC.
12.2.4 Some organic compounds contained in ambient air are
"sticky" and may require repeated analyses before they
fully appear in the FID output. Also* some adjustment
may have to be made In the Integrator off time setting
to accommodate compounds that reach the FID late in the
analysis cycle. Similarly, "sticky" compounds from
ambient samples or from contaminated propane standards
may temporarily contaminate the analytical system and
can affect subsequent analyses. Such temporary contam-
ination can usually be removed by repeated analyses of
humidified zero air.
12.2.5 Simultaneous collection of duplicate samples decreases
the possibility of lost measurement data from samples
lost due to leakage or contamination 1n either of the
canisters. Two (or more) canisters can be filled simul-
taneously by connecting them in parallel (see Figure 2(a))
and selecting an appropriate flow rate to accommodate
the number of canisters (Section 10.2.2). Duplicate (or
replicate) samples also allow assessment of measurement
precision based on the differences between duplicate sample:
(or the standard deviations among replicate samples).
13. Method Modification
13.1 Sample Metering System
13.1.1 Although the vacuum reservoir and absolute pressure gauge
technique for metering the sample volume during analysis is
efficient and convenient, other techniques should work also
13.1.2 A constant sample flow could be established with a vacuum
pump and a critical orifice, with the six-port valve being
switched to the sample position for a measured time period.
-------
T012-28
A gas volume meter, such as a wet test meter, could
also be used to measure the total volume of sample air
drawn through the trap. These alternative techniques
should be tested and evaluated as part of a user-prepared
SOP manual.
13.2 FID Detector System
13.2.1 A variety of FID detector systems should be adaptable to
the method.
13.2.2 The specific flow rates and necessary modifications for
the helium carrier for any alternative FID Instrument
should be evaluated prior to use as part of the user-
prepared SOP manual.
13.3 Range
13.3.1 It may be possible to Increase the sensitivity of the
method by Increasing the sample volume. However,
limitations may arise such as plugging of the trap by 1ce.
* 13.3.2 Any attempt to Increase sensitivity should be evaluated
as part of the user-prepared SOP manual.
13.4 Sub-Atmospheric Pressure Canister Sampling
13.4.1 Collection and analysis of canister air samples at sub-
atmospheric pressure 1s also possible with minor modifi-
cations to the sampling and analytical procedures.
13.4.2 Method TO-14, "Integrated Canister Sampling for Selective
Organlcs: Pressurized and Sub-atmospheric Collection
Mechanism," addresses sub-atmospheric pressure canister
sampling. Additional Information can be found in the
literature (11-17).
