1.0 SUMMARY AND CONCLUSIONS
A study was performed to validate the automated cryogenic
preconcentration and direct flame ionization detection (APDFID) system to
measure ambient air nonmethane organic compound (NMOC) concentrations
continuously. The study was conducted during a four-week period in Raleigh, NC
between July 23 and August 19, 1989. Additional 3-hour, 12-hour, and 24-hour
integrated canister samples were taken and analyzed for NMOC concentration by
the cryogenic preconcentration and direct flame ionization detection (PDFID)
method for comparative purposes.
Temperature, barometric pressure, relative humidity, wind speed, wind
direction, solar radiation intensity, and N02 and NOX concentrations were
recorded throughout the sampling period. The overall 6:00 a.m. to 9:00 a.m.
concentration average was 0.159 ppmC. No trends of NMOC concentrations as
functions of the meteorological variables or humidity were apparent.
No significant differences were detected between APDFID NMOC
concentration measurements and the NMOC concentration measurements made by the
PDFID system using integrated ambient air canister samples. NMOC
concentration measurements by the APDFID system averaged within 10% of the
integrated PDFID measurements.
The integrated 3-, 12- and 24-hour diurnal canister sampling system
operated in an acceptable manner. There was a significant difference between
the weighted average 3- and 12-hour NMOC measured concentrations when compared
to the 24-hour sample concentration.
Another objective of the study was to obtain ambient air NMOC
concentrations throughout the day to help decide the most appropriate time(s)
to sample air for NMOC concentration. For both the 3-hour integrated canister
samples, and the APDFID results, the 6:00 a.m. to 9:00 a.m. samples appeared
to have the highest average NMOC concentration of any of the 3-hour periods
during daylight hours. Since the primary use of the NMOC concentration is to
predict the generation of ozone through the photolysis reactions, it appears
that the 6:00 a.m. to 9:00 a.m. time period is an appropriate averaging
period.
jlh.006 1
-------
To determine whether a different time interval is more appropriate,
would require comparing an ozone prediction model with actual NMOC, NOX, and
03 data throughout daylight hours, and/or predaylight hours, to determine
which time interval resulted in the closest fit to the model. Such a
comparison was beyond the scope of this study.

2.0 INTRODUCTION
From July 23 through August 19, 1989 Radian Corporation field tested two
approaches for obtaining NMOC concentrations throughout the 24-hour day. The
first approach involved the use of an APDFID instrument which was capable of
automatically acquiring, cryogenically preconcentrating, and analyzing ambient
air for NMOC. The APDFID instrument had the capacity to take and analyze
about four NMOC concentration measurements per hour. The instrument took an
integrated 9-minute sample and analyzed the sample during the next 6-minutes.
The complete sampling analysis cycle was about 15 minutes. The instrument is
designed to operate unattended 24-hours per day.
The second approach involved the use of SUMMA®-treated stainless steel
canisters to acquire six integrated ambient air samples for various segments
of the day. Three-hour integrated whole ambient air samples were taken every
other day from 6:00 a.m. to 9:00 a.m., 9:00 a.m. to noon, noon to 3:00 p.m.,
and 3:00 p.m. to 6:00 p.m. A 12-hour sample was taken from 6:00 p.m. to
6:00 a.m., and a 24-hour sample was taken from 6:00 a.m. to 6:00 a.m. These
six integrated samples were taken and analyzed to verify and confirm the
results of the APDFID instrument.
All sampling was done at the U.S. Environmental Protection Agency 1989
Raleigh (RLNC) NMOC monitoring site.1 Both the automated and integrated
diurnal ambient air samples were taken from a common sampling manifold, and
analyzed by the PDFID methodology described in Compendium Method TO-12.2
Samples collected and analyzed for the APDFID diurnal study and for the EPA
NMOC site at Raleigh were included in this study for comparison purposes. The
standard NMOC samples from the Raleigh site were included because they
represent data from a collocated site. In addition to the NMOC results,
meteorological data (wind speed, wind direction, relative humidity, solar
radiation intensity, and temperature) were continuously recorded for the
entire duration of the study. Hourly station barometric pressure readings
were obtained from the weather bureau at the Raleigh-Durham airport.
Three types of samples are discussed in this report: (1) The RLNC
samples came from the Raleigh, NC site and were 6:00 a.m. to 9:00 a.m.
jlh.006 3
-------
integrated canister samples collected with separate NMOC Monitoring Program
samplers and analyzed by the PDFID method; (2) Integrated diurnal samples were
collected on the manifold diagrammed in Figure 1 and analyzed by the PDFID
method according to the schedule specified in Table 1; and (3) APDFID samples
(9-minute samples) were taken approximately four times per hour. The APDFID
samples were integrated to one-hour averages. The one-hour averages were also
averaged into various time intervals to compare the APDFID results with the
RLNC samples and the integrated diurnal samples.
2.1 OBJECTIVES
The primary objectives of the automated and diurnal NMOC sampling
study were:
1. To obtain the NMOC concentration data with integrated 3-hour,
12-hour, and 24-hour samples (and with automated 24-hour data),
necessary to help decide the most appropriate time(s) during the
day to sample air for its NMOC concentration; and
2. To validate the mechanical reliability, precision, and accuracy of
the APDFID instrument in sampling ambient air and analyzing its
NMOC concentration continuously for a four-week period.
An additional objective was to relate the NMOC concentration to
temperature, humidity, solar radiation intensity, and a wind velocity vector
directed from the potential sources of air-borne organic chemicals to the
site. The main source of air-borne organic chemicals near the RLNC site was
from automobile traffic on North Boulevard (U.S. 1) about 1500 feet west of
the site.
2.2 EXPERIMENTAL APPROACH
Table 1 gives the monitoring sample schedule for both the automated and
integrated diurnal samples. Both types of samples were obtained for a
four-week period. The automated unit was calibrated (zero and span) every
other day using a propane standard referenced to a National Institute of
Standards and Technology (NIST). The automated and diurnal study sampling
device was separate from the sampling manifold3 used for the 1989 Raleigh NMOC

Monitoring Program site. Figure 1 shows a schematic diagram of the sample
manifold used for both the automated and integrated diurnal samples. The
sampling manifold inlet for the automated and diurnal samples was collocated
with the sample inlet for EPA's 1989 Raleigh NMOC monitoring site, and was 12
feet above ground level. Three-hour, 12-hour, and 24-hour integrated whole
ambient air samples were taken in 6-liter (L) stainless steel canisters. The
RLNC samples were 3-hour integrated whole ambient air samples taken in
canisters from 6:00 a.m. to 9:00 a.m., Monday through Friday. Simultaneously,
an APDFID instrument was used to acquire and analyze four 9-minute NMOC
samples per hour, 24 hours per day for the full 4-week sampling period. The
APDFID system was not able to sustain 24-hour sampling for long periods of
time. The reasons for sampling interruptions are discussed below along with a
discussion of measures which could overcome the problems and enable the
instrument to operate reliably over longer periods of time. As noted in Table
1 the APDFID instrument was calibrated every other day. This caused a planned
one-hour interruption in the APDFID sample acquisition schedule.
The automated monitoring, and diurnal sampling matrix is given in
Table 1. Sample Numbers 1 through 8 distinguish between the several types of
samples being taken during the study. Sample No. 1, the regular 6:00 a.m. to
9:00 a.m. NMOC Monitoring Program (RLNC) sample was collected at the Raleigh
site and analyzed at Radian's Research Triangle Park, NC laboratory. Sample
No. 1 used a separate sampling train and inlet manifold, and samples were
acquired Monday through Friday from June 5, 1989, through September 29, 1989.
Integrated diurnal samples (Samples Nos. 2 through 7) were collected
every other day, including Saturday and Sunday, over the four-week study
period. Sampling times were set so that "Sunday" samples, for example, began
at 6:00 a.m. on Sunday. The 24-hour sample scheduled to begin at 6:00 a.m.
Sunday extended to 6:00 a.m. on Monday. Likewise the 12-hour integrated
sample scheduled to begin on Sunday at 6:00 p.m. extended to 6:00 a.m. on
Monday. Three-hour diurnal samples were taken during daylight hours according
to the schedules shown in Table 1.

3.0 RESULTS
The results for this study are discussed and compared in three ways. The
results discussed in this section include those from the RLNC samples, the
integrated diurnal samples, and the APDFID samples. The purpose of showing
all the data is to demonstrate how the 6 a.m. to 9 a.m. NMOC concentrations
during the sampling interval for the diurnal sampling period (July 23 through
August 19) fit into the overall 6 a.m. to 9 a.m. NMOC concentrations for the
entire summer.
NMOC concentrations for the 6 a.m. to 9 a.m. diurnal integrated samples
are compared to the RLNC NMOC concentrations in Table 3. The APDFID data are
presented and compared to the data from integrated diurnal samples and the
RLNC samples in Table 4. Finally, the APDFID results are characterized by
hours, sample periods, and as functions of meteorological variables.
3.1 1989 RALEIGH, NC MONITORING PROGRAM
The NMOC concentrations from the 1989 Raleigh, NC monitoring site are
given in Figures 2, 3, and 4. The RLNC samples include all the data from the
1989 NMOC Monitoring Program at Raleigh, NC for the period from June 5 through
September 29, 1989. Figure 2 shows the NMOC concentrations on the vertical
axis with the same scale used for sites in the 1988 NMOC Monitoring Program
Final Report/ This scale shows the relative magnitude of RLNC measurements
to the scale required to accommodate other sites around the U.S. Two
horizontal lines are shown in Figures 2 and 3 representing the RLNC mean NMOC
concentrations equal to 0.159 ppmC, and the overall mean NMOC concentration of
0.583 ppmC at 21 sites in the 1989 NMOC Monitoring Program. The Raleigh 1989
NMOC mean concentrations averaged about 1/3 the value of the overall mean
concentrations at 21 sites in 1989.
Figures 2 and 3 also show the period of time in which diurnal sampling
took place, from 1989 Julian date 204 (July 23) through 1989 Julian date 230
(August 19). Figure 4 displays the NMOC Monitoring Program concentrations at
the 1989 RLNC site in a stem-and-leaf plot. The column of digits on the left
are the stems and the series of digits on the left are the leaves, and are
separated from the stems by an open channel. The minimum concentration is the

first 4 in the first leaf (at the top of the plot) and is equal to 0.043 ppmC;
the maximum concentration is in the lowest leaf at the bottom of the plot and
is equal to 0.551 ppmC. Each NMOC concentration analyzed from the 94
integrated morning ambient air samples is plotted, depending on its magnitude
in one of the leaves of the plot. "M" on the plot locates the stem of the
median, which is 0.131 ppmC. The median indicates that 50% of the NMOC
concentrations are less than that of the median, while 50% are larger. "H"
marks the stems for the upper and lower hinges. The hinges divide the median
into half again, so that 25% of the NMOC concentrations are smaller than the
lower hinge (0.083 ppmC at the top part of the plot); and the upper hinge,
0.209 ppmC marks the concentration which is larger than 75% of the NMOC
concentrations measured. The stem-and-leaf plot shows the data to be
approximately lognormally distributed which is consistent with the frequency
distributions found previously.4
Table 2 summarizes the 1989 RLNC site data for several periods
throughout the summer. The data were divided into months and statistics were
calculated for each month. In addition, summary statistics are shown for the
period of July 23 through August 19, 1989 which was the time period during
which the diurnal sampling was taking place. The results show that the NMOC
median concentration was highest in June, declining every month through
September. The median concentration during the diurnal sampling period was in
line with the concentrations throughout the remainder of the summer.
3.2 DIURNAL SAMPLES
Two kinds of diurnal samples were obtained and analyzed. One type
included the 3-, 12-, and 24-hour ambient air samples, which we have called
integrated diurnal samples, and which were taken in SUMMA* treated canisters
and analyzed by PDFID. The second type of diurnal samples were taken from the
sampling manifold and analyzed by the APDFID system. Hourly concentrations
for the APDFID samples were numerically integrated from
9-minute sample intervals, and then appropriate 3-, 6-, and 24-hour averages
of the hourly APDFID results were compared to the NMOC concentrations from the
integrated diurnal canister samples. The RLNC 6:00 a.m. to 9:00 a.m.
integrated samples were compared to the diurnal integrated 6:00 a.m. to 9:00
a.m. canister samples in Section 3.2.1.

Each of the comparisons performed to evaluate the equivalency of the
integrated canister samples analyzed by the PDFID method with the APDFID
samples averaged over the same time periods, is described in this section.
3.2.1 Raleigh Monitoring Program Samples vs. Diurnal Samples
In Table 3, the 6:00 a.m. to 9:00 a.m. NMOC concentrations for the
integrated diurnal samples are compared to the NMOC concentrations for the
RLNC samples (also 6:00 a.m. to 9:00 a.m.). The second column in Table 3
gives NMOC concentrations for the RLNC samples and the third column gives the
integrated diurnal sample concentrations for the 6:00 a.m. to 9:00 a.m.
interval. The fourth through the seventh columns give statistics comparing
the concentrations of the two samples. Difference is defined relative to the
RLNC sample:
Difference = (Diurnal RLNC). (1)
Percent difference is defined as:
% Difference = (difference/average) x 100, (2)
where average is the mean of the RLNC and the diurnal sample concentrations.
Absolute % difference is the absolute value of % difference. Averages and
standard deviations of all columns except the first column are given. By
inspection, average difference, average % difference, and average absolute %
difference are not significantly different from zero.
Average % difference and average absolute % difference may be compared
to similar statistics for 1988 NMOC Monitoring Program duplicate samples/
For the 1988 duplicate samples average % difference was equal to 0.313
compared to 1.524 for the duplicate pairs in Table 3. Absolute % difference
for the 1988 NMOC Monitoring Program averaged 8.72 compared to 12.82 for the
RLNC-Diurnal samples.
Figure 5 offers an explanation for the observed behavior. Duplicate
sample concentrations for the 1988 Monitoring Program averaged 0.591 ppmC,
while Table 3 shows the 6:00 a.m. to 9:00 a.m. diurnal samples to average

0.169 ppmC. Figure 5 was taken from the 1988 NMOC Final Report4 and shows
that as the average NMOC concentration decreases below 0.5 ppmC, the average %
difference increases rapidly. At an average duplicate sample concentration of
0.169 ppmC, Figure 5 shows an average % difference of about 12.75 which is in
line with the calculated average absolute % difference of 12.82.
3.2.2 Integrated Diurnal Samples at Six Sampling Periods
Table 4 gives the results of the analysis of integrated ambient air
samples over the diurnal sampling periods shown. The sample numbers shown in
Table 4 correspond with those indicated in Table 1. Diurnal Sample #2
(D.S. #2) was the integrated canister sample taken from 6:00 a.m. to 9:00 a.m.
Diurnal Average #9 is a weighted 24-hour average calculated according to
Equation 2.
Average #9 = (3 x D.S.#2 + 3 x D.S.#3 + 3 x D.S.#4 + 3 x D.S.#5
+ 12 x D.S.#6)/24. (3)
Weighted 24-hour average #9 (Equation 3) is compared to the measured 24-hour
average, D.S. #7, in the last four columns of Table 4. Column 9 is the
difference between average #9 and D.S. #7. Columns 10, 11, and 12 are their
average, % difference, and absolute % difference respectively. Although the %
difference ranges from -3.93 to 31.58, the average % difference is a moderate
13.30. There appears to be a positive bias in the difference, however.
Student's t test, testing the hypothesis that the mean difference is zero,
concludes by rejecting the null hypothesis (Ho: pd = 0) at the 0.05 level of
significance. If the conclusion were reached that there was a positive bias
in the average differences, the probability is 95% that we have reached the
correct conclusion.
This means that the weighted 3- and 12-hour average #9 gives a
statistically significantly higher average than the 24-hour D.S. #7. A
possible explanation for this occurrence is that the samples in some of the
sampling periods were not fully integrated samples. Another explanation may
be that the sampling and analytical errors in the data set of this study were

lower than the typical errors encountered in this kind of measurement, i.e.the
standard deviations were unusually low for the NMOC concentration range
encountered.
Further comparisons of these data tested whether a significant
difference was apparent between the sampling periods. Table 5 compares the
average NMOC concentrations for each sampling period (#3 through #6) with the
average concentration for the 6:00 a.m. to 9:00 a.m. period. The Null
Hypotheses for these tests are shown in column one of the table. The degrees
of freedom for the test, the test statistics,and the critical test statistic,
t are given in the remaining columns of Table 5. The only null
hypothesis that can be rejected, at the 0.05 level of significance is the last
one M2 = M6> because the test statistic, t = 2.222, is greater than the
critical statistic, t23> 0 975 = 2.069. The results of this study indicate that
the average concentration of NMOC collected in the 6:00 p.m. to 6:00 a.m.
samples was significantly higher for this study than the average
concentrations of the 6:00 a.m. to 9:00 a.m. samples.
These results indicate that the building of NMOC concentration during
the night is greater than the average NMOC concentrations in the 6:00 a.m. to
9:00 a.m. time period. It is to be noted that photochemical reactions in the
6:00 a.m. to 9:00 a.m. time interval would not be expected to be as large as
in the 9:00 a.m. to 3:00 p.m. time period.
3.2.3 APDFID Samples Compared to Diurnal Samples
Table 6 compares the average APDFID sample concentrations with the
integrated canister concentrations for the same sampling period, analyzed by
PDFID. The second column, Wj, designates the weekday (Sunday, Wj=l, Monday,
Wj=2, ..., Saturday, Wj=7). The column marked Pk represents different time
periods throughout the day. (Time Period Pk=l is for 6:00 a.m. to 9:00 a.m.;
Pk=2 is for 9:00 to Noon; Pk=3 for Noon to 3:00 p.m.; Pk=4 for 3:00 p.m. to
6:00 p.m.; Pk=5 for 6:00 p.m. to 6:00 a.m.; Pk=6 for 6:00 a.m. to 6:00 a.m.).
Difference, % difference, and absolute % difference are calculated in a
manner similar to the statistics in Table 4 using the integrated PDFID
concentration as the reference value. Percent difference and absolute %

difference reference the differences to the average of the two concentrations.
The average difference between the APDFID and PDFID concentrations is -0.0105
ppmC, which is not significantly different from zero at 0.05 level of
significance. Likewise, the average % delta is -10.2, which is also not
significantly different from zero. The absolute % difference is about 31%,
which appears to be large. In view of the overall average NMOC concentration,
equal to about 0.11 ppmC, however, the precision of 31% is a reasonable value.
Therefore, we conclude APDFID and integrated canister diurnal NMOC
concentrations are equivalent. Likewise the APDFID instrument and the
canister 3-hour samples analyzed by the PDFID method give equivalent results.
3.3 APDFID DATA CHARACTERIZATION
The APDFID NMOC concentrations were obtained by the automatic analysis
of 9-minute samples. The time interval for the sampling/analysis cycle of the
APDFID instrument varied from 16 to 19 minutes. The data were numerically
integrated by the trapezoidal rule to give hourly average NMOC concentrations.
The hourly average NMOC concentrations determined by the integration of the
APDFID measurements are shown in the stem-and-leaf plot of Figure 6.
Statistics for the 248 APDFID hourly measurements are shown in Figure 6.
Also shown are the 6:00 a.m. to 9:00 a.m. PDFID measurements taken at the RLNC
site for the entire summer monitoring program. The PDFID statistics are seen
to be larger except for the number of cases, the maximum , the skewness, and
the kurtosis. The standard deviations of the APDFID hourly NMOC concentration
are about equal to the 3-hour 6:00 a.m. to 9:00 a.m. integrated samples for
the entire summer. These observations regarding the 6:00 a.m. to 9:00 a.m.
RLNC Monitoring Program NMOC concentration distribution as compared to the
PDFID measured NMOC concentration distribution for all hourly time intervals,
lend credence to the assertion made earlier that the APDFID and the integrated
canister concentration (analyzed by the PDFID method) are equivalent.
Table 7 shows various hourly statistics for the 1989 Raleigh diurnal
APDFID NMOC data. The first row shows the same statistics given in Figure 6
for all of the combined APDFID data. Subsequent rows in Table 7 summarize the
minimum, the mean, the median, the maximum, the range, and standard deviations

each hour of the day.
Figure 8 plots the minimum, mean and maximum for each hour of the day.
Figure 9 plots the median NMOC concentration for each hour of the day.
Figures 7 and 8 show a significant increase in the average NMOC
concentration from 6:00 a.m. to 9:00 a.m. (hours 7,8, and 9), while the
average NMOC decreases, as expected, for hours 12, 13,and 14. For hours 15
through 4, Figure 8 shows that the maximum NMOC concentration for each hour
was greater than 0.3 ppmC, although the average hovered around 0.1 ppmC. The
median followed the same trends except for hour 8 (7:00 a.m. to 8:00 a.m.)
which was below the overall average median.
Figure 10 shows boxplots of the NMOC concentrations for each hour of the
day. The rectangles for each hour show the midrange of the data. The
horizontal line inside the rectangle marks the NMOC concentration of the
median. The upper and lower ends of the rectangle mark the upper and lower
hinges of the ranked data. Three quarters of the data are smaller than the
upper hinge and one quarter of the data is smaller than the lower hinge. The
absolute difference between the upper and lower hinge is called the Hspread.
Inner fences are defined as follows:
lower inner fence = lower hinge (1.5 x Hspread), and (4)
upper outer fence = upper hinge + (1.5 x Hspread). (5)
The outer fences are defined as follows:
lower outer fence = lower hinge - (3 x Hspread), and (6)
upper outer fence = upper hinge + (3 x Hspread). (7)
Values outside the inner fences are plotted with asterisks. Values outside
the outer fences are plotted with empty circles. Whiskers extended from the
boxes to the extreme (maximum and minimum) values or to the inner fences,
whichever give shorter whiskers. The boxplots give a general impression of
the overall level, the amount of spread of the data, symmetry, and the
presence or absence of outliers. Figure 10 shows the presence of outliers,
some of which are greater than 0.4 ppmC. The boxplots show that the NMOC data

boxplots for hours 8 and 9 show large spans of data, whereas for hour 10, 13,
and 14, the overall spans are much smaller. The NMOC levels of the medians
for the boxplots should correspond to the medians plotted in Figure 9.
Boxplots are a compact way of indicating the character and distribution of the
hourly NMOC readings.
3.3.1 Correlations Among APDFID Data
Nine-minute APDFID samples were taken at intervals ranging from 16 to 19
minutes. As indicated earlier, the data were integrated to give hourly
averages. The hourly averages are recorded in Appendix B along with hourly
average valves of wind speed, wind direction, temperature, solar radiation
intensity, percent relative humidity, and station barometric pressure (at the
station at Raleigh-Durham airport). Appendix B also indicates the 1989 Julian
date, and a column labeled "Diurnal Minutes." Diurnal minutes were defined to
simplify the integration calculations as follows:
Diurnal minutes = (Julian date 203) x 1440 (8)
+ (hour x 60).
Diurnal minutes are tabulated as a function of 1989 Julian date and hour
throughout the day in Appendix A.
The hourly average data were converted to absolute units: wind speed and
wind direction were converted to hourly average velocity vectors perpendicular
to the highway (U.S. 1) in the direction of the RLNC site; temperature was
converted to kelvins; solar radiation units were converted to joules per
square meter (J/m2) and percent relative humidity was converted to mole
fraction water. These conversions were made so that the variables could be
used in the various correlations and analyses of covariance described below.
The hourly average concentrations were averaged over the six sampling periods
(Pk) given in Table 1. The APDFID and the PDFID (integrated) concentrations
averaged over the sampling periods were given in Appendix C, along with
diurnal minutes, temperature (kelvins), solar radiation (J/m2), humidity (mole
fraction), velocity vector (m/s), Si, Wk, Pk, and NMOC concentration (ppmC).
jlh.006 30
-------
Variable Si is a fixed variable indicating whether the results were obtained
from APDFID (Si=l) or from the PDFID (Si=2) measurement. Wk indicates the
weekday, Sunday, Wk=l, Monday, Wk=2, etc. through Saturday, Wk=7.
Table 8 gives the correlation matrix for the diurnal variables and
includes data from PDFID as well as APDFID NMOC concentrations. The table
gives binary correlation coefficients for the eight variables shown. Only one
variable pair shows a significant correlation, and that is the T-H pair.
Because the temperature is used to calculate the vapor pressure of water used
to calculate the humidity, a correlation of these two variables is not
unexpected. No other variable pair shows a significant correlation, with
r > 0.9. The Bartlett chi-square statistic shown in Table 8 tests the global
hypothesis concerning the significance of all the correlations in the matrix.5
With the probability in the Bartlett chi-square test equal to zero, the test
is significant which indicates that there may be some real correlations among
the variables. The relationship between temperature and humidity have already
been cited. One of the objectives of the study was to determine which among
the variables, T, SRAD, H, V, S, W, and P, might be significant independent
variables, using NMOC as a dependent variable. The bottom row in the
correlation of matrix shown in Table 7 indicates that a correlation between
NMOC and other variables is not likely. In order for a correlation to be
likely, the correlation coefficients should be in the range between 0.75 and
1.0 and -0.75 to 1.0
A number of analyses of covariance (ANOCOVA) were performed on the data
and their results are summarized in Table 9. Variables S,P, and W were fixed
variables while T, SRAD, and V were continuous variables. The humidity
variable, H, was not used as an independent variable because of its dependence
on T. As seen in Table 8, H, has the highest correlation with the other
variables, except for NMOC. Variable H was therefore not used in the ANOCOVA,
where NMOC was the dependent variable.
It is difficult to interpret the results of the ANOCOVA. The most
general conclusion that can be reached is that the NMOC concentration was so
low, and the variability was also so low that assigning significant trends was
not possible. The SP, or S x P, interaction term appeared to be significant
whenever S and P were used as independent variables.

-------
Whenever P and SRAD were used as independent variables in the same ANOCOVA,
neither was significant. However, T and SRAD appeared to be significant when
used as independent variables in the absence of P as an independent variable.
Using T2 in place of T as an independent variable did not appear to increase
the overall correlation significantly. In no case did V become a significant
variable. Variable S was significant in only one case, Case No. 10.
There were sufficient cases in the ANOCOVA in which one variable or
another was significant, to suggest that with NMOC data having a larger range
of variability and magnitude, there would be clearer trends of cause and
effect between the independent and dependent variables.
Table 9 shows the multiple correlation coefficients, R, to range between
0.343 to 0.609, averaging about 0.44. Such a range indicates that additional
other independent and/or dependent variables need to be used to improve the
correlations. Perhaps a better dependent variable would be the ratio of
NMOC/NOX. Using NMOC as one of the independent variables with NOX, or 03 as
the dependent variable may also give better correlations.

4.0 EQUIPMENT PERFORMANCE
One of the primary objectives of the study was to validate the
mechanical reliability and precision of the APDFID apparatus. Integrated 3-
hour, 12-hour, and 24-hour diurnal whole air canister samples were used to
validate the APDFID results.
The diurnal sample collection system yielded a project completeness of
96.1%, whereas the APDFID system yielded a completeness of about 40%. As a
result of the field test of the APDFID system a number of modifications were
suggested to improve the APDFID completeness.
The diurnal sampling system will be described below and will be followed
by a description of the APDFID system.
4.1 DIURNAL INTEGRATED SAMPLING SYSTEM DESCRIPTION
As seen in Figure 1, the APDFID and the diurnal collection systems
shared a common 1/4-inch outside diameter (o.d.) stainless steel sampling
manifold having an inverted glass funnel at the inlet and a high flow slip-
stream pump at the outlet. The glass-funnel inlet for the diurnal sampling
system was placed within 6 inches of the inlet for the Raleigh, NC (RLNC) NMOC
Monitoring Program site. The slipstream pump for the diurnal sampling system
maintained at least 12 liters per minute (L/min) through the manifold. The
diurnal sample collection system consisted of three subsystems: (1) a
subsystem for the 3-hour integrated samples, (2) a system for the 12-hour
integrated sample, and (3) a system for the 24-hour sample.
4.1.1 Three-hour Integrated Sample Collection System
The first port on the sampling manifold from the sample manifold inlet
was used for the 3-hour samples. The collection system consisted of a 2-
micron (/x) stainless steel filter housed in a filter assembly, a fixed orifice
assembly, a Metal Bellows MB-151 pump, programmable electronic timers, and a
1/8-inch o.d. manifold from which were located four branches each connected to
a 6-L stainless steel canister through a separate Magnalatch latching solenoid
jlh.006 35
-------
valve. The fixed orifice assembly contained a 75-milliliter per minute
(mL/min) critical orifice. The MB-151 pump provided the pressure drop for the
critical orifice and was started and stopped by its own dedicated programmable
electronic timer. By the end of each sampling period, the MB-151 pump also
provided a pressure of about 15 psig in the sample canister. The schedule of
activity for collection of integrated samples and operation of the Magnalatch
valves is given in Table 10. The 6:00 a.m. to 9:00 a.m. sample was terminated
at 8:58 a.m., giving a 178-minute sample (out of 180-minute time period). The
9:00 a.m. to Noon integrated sample began sampling at 9:01 a.m. and was
terminated at 11:58 a.m. giving a 177-minute sample out of a 180-minute time
period. An interval of about three minutes was provided between the time one
sample collection was completed and another began. This static period was
required because of the common delivery manifold shared by the diurnal
samples. If the solenoid valves, on a system that had just collected sample
at (about 15 psig) and a system that had not collected sample (under 15 mm Hg
vacuum absolute) were ever open at the same time, there would be a flow of
sample from one canister to the other. Both samples would be contaminated in
reaching pressure equilibrium.
4.1.2 Twelve-hour Integrated Sampling System
Integrated samples were collected during the 12-hour period 6:00 p.m.
and 6:00 a.m. (6:00 p.m. to 5:59 a.m.). The collection system was the second
port in the main sampling manifold shown in Figure 1. The 12-hour sampling
system with a stainless steel filter, and micro-metering valve, had its own
programmable electronic MB-151 pump, Magnalatch solenoid valve, and digital
timer. The micro-metering valve was set for a flow of 19 mL/min and the timer
was set to activate and deactivate the MB-151 pump and the Magnalatch solenoid
valve both at the times shown in Table 10.
4.1.3 Twenty-four-hour Integrated Sampling System
The 24-hour sampling system was the third port on the main sample
manifold from the sample inlet. Integrated samples were collected in 6-L
canisters during one 24-hour period of each sampling episode. The collection

system was configured exactly the same as the 12-hour collection system except
that the micro-metering valve was set for a flow of 10 mL/min. As shown in
Table 9, the 24-hour sampling period was set for the integration period
between 6:00 a.m. on the day designated as the sampling date and 5:59 a.m. the
next day.
All of the diurnal integrated sample equipment operated as designed.
Completion in terms of % of valid samples was 96.1. Three samples were voided
because of incorrect settings programmed into the timers.
4.2 AUTOMATED CRYOGENIC PRECONCENTRATION AND FLAME IONIZATION
DETECTION SYSTEM
The APDFID instrument operating cycle is described in a previous
report.6 One of the objectives of the study was to determine the reliability
of the system under field conditions and how well the measurements of NMOC
concentration agreed with the measurements obtained from integrated canister
samples analyzed by the PDFID method.
Approximately 40% data capture was achieved with the APDFID instrument
during the course of the study, but sufficient experience was gained to
develop some solutions to of the problems causing data interruptions. APDFID
operating limitations experienced in the field included excessive cryogen
usage, ice accumulation, power outages and computer lockups due to noise
spikes.
About one tank of cryogen (160 L) was used per day prior to finding
cryogen leak at the sample trap. Once the leak was corrected, the amount of
cryogen used to maintain the trap temperature decreased to about one tank
every two days.
Ice accumulation around the cryogenic solenoid valve and cryogen lines
leading to the trap created FID electronic noise problems. The signal cable
leading form the FID to the electrometer, and the FID support gas lines, were
often encased in ice. This problem was resolved after discovery by tightly
packing the cryogen solenoid and lines with closed cell insulation material.
Power outages, although infrequent, created down time because the gas
chromatograph's operating method would reset. Once the method was reset no
other samples were taken. Short power spikes often locked-up the computer,
jlh.006 38
-------
but did not reset the GC. The Nelson data system software interrupted the
signal transfer from the GC to the computer's hard drive. Once the computer
was locked-up, the Nelson data system interface could not transfer any data to
the hard drive of the computer. The Nelson interface would then store a
certain number of sample runs in its on-board memory buffer. Once the on-
board buffer was full, no subsequent sample runs were stored. Therefore, if
the computer was not able to download data, only a limited number of runs were
obtained by the interface. If the power went out during the computer lockup
period, then all data in the interface were lost.
4.2.1 Recommended Modifications for the APDFID System
Cryogenic sample trap modification could decrease the amount of cryogen
needed to maintain the temperature. A change in the trap material to
aluminum, instead of copper, should increase the cooling and heat-transfer
efficiency by 30%. The reduction in size of the insulated cavity around the
sample trap and increasing the volume of insulation encasing the trap chassis
should also decrease the cryogen use.
Moving the cryogenic solenoid valve and cryogen lines away from the GC
electronics area to a location outside of the GC will reduce FID electronic
noise. Any ice accumulation and water due to frost formation and defrost will
not affect the instrument operation and electronics.
An uninterruptible power supply to support the computer and Nelson
interface will solve any computer lockup problems experienced by power spikes
that do not reset the GC. The proposed modifications to the APDFID system are
expected to reduce the cryogen usage by approximately 50%, and to increase the
data capture to a goal of 70%.
4.3 APDFID CALIBRATION, AUDIT AND ZERO RESULTS
For initial calibration purposes, APDFID used propane referenced to
National Institute of Science and Technology (NIST) propane standards, as
required by Compendium Method TO-12. Calibration checks of response factors
for propane and zeros, using zero-grade air, were performed every other day
throughout the diurnal sampling project.
jlh.006 39
-------
4.3.1 Initial Calibration of the APDFID system
Initial calibration for the APDFID was performed using n-propane
standards referenced to NIST standards. The propane calibration curve for the
APDFID apparatus is given in Figure 11. Zero readings of the calibration
curve were measured using a zero-air cylinder. The correlation coefficient
for the calibration curve was 0.99650.
4.3.2 Daily Response Factors
Response factors were measured every other day using propane with a
concentration was about 3.0 ppmC. Figure 12 shows response factors measured
over the diurnal sampling period. Four horizontal lines are shown on
Figure 12, /x +/- 2a, and M +/- 3a. The n +/- 2a lines are called warning
limits, and the n +/- 3a lines are the control limits. The response factor
chart appears to be showing a rising trend in the response factor with time.
The data, however, remain within the warning limits. The "runs", or
consecutively increasing measurements appear to be no more than five, so the
APDFID measurement/calibration check systems appear to remain in control. For
future tests with the APDFID system this increase needs to be monitored
closely.
4.3.3 Audit Results
Two audit samples containing propane were supplied by the Quality
Assurance Division of the U.S. Environmental Protection Agency to determine
accuracy of the APDFID instrument. The first audit sample dated
July 31, 1989, had a concentration of 0.724 ppmC; and the second audit sample
had a concentration of 0.791 ppmC. The analyses of these audit samples by the
APDFID instrument showed a bias of +1.52% and 13.40% respectively, for an
overall average of -5.94%.
Audit (and precision) results for the analyses conducted by the PDFID
analyses of integrated canister samples were periodically conducted on the

1989 NMOC Monitoring Program. With this analytical instrumentation audit
results are typically less than +5%. In 1988, for example, audit results for
the four Radian channels were +2.22%, +1,33%, +2.86%, and +4.51%.* The
results from the audits will be reported in the 1989 NMOC Monitoring Program
final report, which is currently in preparation.
4.3.4 Daily Zero
Zero measurements were performed every other day using zero-grade air
from a storage cylinder. The daily zero results are shown in Figure 13.
Horizontal lines are also shown in Figure 13 at y. +/- 2a and /x +/- 3a for the
daily zero measurements. Because the magnitude of the early "zero"
measurements (Julian dates 205 - 218) were in the same order of magnitude as
the NMOC measurements at the Raleigh site, the "daily" NMOC measurements were
also plotted in Figure 13. The zeros appear to show some carryover from the
NMOC measurements themselves. Unfortunately it was not always possible to
plot the "Daily" NMOC measurement performed immediately prior to the zero
measurement. The "daily" NMOC concentration shown in Figure 13 was either the
overall daily average NMOC, the 6:00 a.m. to 9:00 a.m., or sometimes the 3:00
p.m. to 6:00 p.m. NMOC concentration measurement.
Nevertheless, there appears to be an approximate correlation between the
daily NMOC concentration measurement and the zero concentration, perhaps with
some lag involved. It is to be emphasized, however, that the concentrations
of NMOC were generally so low that such a correlation is tentative at this
time. The fact that there normally is such a short time between APDFID
measurements, and that purging the cryogenic trap between sampling episodes
was brief, could lead to the hypotheses that there may be some carryover of
organic material from one sampling episode to the next. Before a more
definite evaluation of this phenomenon is made, it will be necessary to carry
out additional tests at higher overall NMOC concentration in the range of
average concentration above 0.750 ppmC.

5.0 CONCLUSIONS
The following is a summary of conclusions drawn from this study.
1. Diurnal integrated samples compared well with APDFID samples. The
difference averaged 0.011 ppmC. Percent differences ranged between
-87.5 and +58.0 and averaged -10.23. The average absolute % difference
was 31.0. No significant differences between the APDFID and the PDFID
methods of measurement of NMOC concentration were detected.
2. Diurnal 6:00 a.m. to 9:00 a.m. integrated sample concentration averaged
significantly lower than diurnal integrated sample concentrations
collected from 6:00 p.m. through 6:00 a.m., at the 0.05 level of
significance.
3. The average 6:00 a.m. to 9:00 a.m. NMOC concentration at the Raleigh, NC
Monitoring Program site for the summer of 1989 was 0.159 ppmC, which was
smaller than the site averages at any of the 38 morning monitoring sites
during the summer of 1988.
4. Hourly averages of NMOC concentrations measured by the APDFID system
were approximately lognormally distributed and ranged from 0.017 ppmC to
0.829 ppmC. The average concentration was 0.112 ppmC and the median was
0.078 ppmC. The lower hinge was 0.056 ppmC and the upper hinge was
0.114.
5. No trends of NMOC concentration, measured by the APDFID system were
discernable as functions of temperature, solar radiation intensity,
humidity, or wind velocity vector from the largest NMOC source in the
vicinity of the sampling site.
6. The Raleigh NMOC Monitoring Program sample concentrations compared
favorably with the diurnal 6:00 a.m. to 9:00 a.m. integrated whole
ambient air samples. There was, on the average, only a -0.007 ppmC
difference which resulted in a -1.52% difference. The average absolute
% difference was 12.8.
7. The weighted average of the 3- and 12-hour integrated diurnal NMOC
sample concentrations was significantly higher than the average of the
24-hour sample concentrations.

-------
8. Hourly medians for 6th, 7th, 9th, 10th, 20th, 21st, 22nd, 13th, 14th,
15th, 16th, and 17th hours were significantly less than the overall
average medians.
9. Hourly averages followed similar trends although the trends for hourly
averages were less well defined because of the presence of a number of
outliers among the hourly averages.
10. The low overall NMOC concentration during the study caused the
interpretation of hourly NMOC trends to have large uncertainties.
11. No differences in average NMOC concentration measured by the APDFID
system were discernable among the days of the week.
12. Zero air measurements performed every other day during the APDFID
sampling period suggested that there may be carryover from one nine-
minute APDFID measurement to the next. The magnitude and extent of the
carryover was not possible to determine because of the low overall NMOC
concentration encountered in the study.
13. The 1989 Raleigh Diurnal study with the APDFID apparatus suggested
several changes in equipment and operating procedure that would improve
the data capture from about 40% to a goal of 70%.
14. The average 6:00 a.m. to 9:00 a.m. NMOC concentration for the period
from June 5 through June 30, 1989 was significantly higher than the
average NMOC 6:00 a.m. to 9:00 a.m. concentration for September 1989.
15. The average 6:00 a.m. to 9:00 a.m. NMOC concentration decreased each
month from 0.2063 ppmC in June 1989 to 0.1200 for September.
16. The 6:00 a.m. to 9:00 .m. concentrations at the Raleigh, NC monitoring
site during the period of the diurnal sampling (July 23 to
August 19, 1989) was not a significantly different from the average
NMOC concentration for the entire summer of 1989.
