RESEARCH REPORTING SERIES
Research reports of the Office of Research and Development, U.S. Environmental
Protection Agency, have been grouped into five series. These five broad
categories were established to facilitate further development and application of
environmental technology. Elimination of traditional grouping was consciously
planned to foster technology transfer and a maximum interface in related fields.
The five series are:
1. Environmental Health Effects Research
2. Environmental Protection Technology
3. Ecological Research
4. Environmental Monitoring
5. Socioeconomic Environmental Studies
This report has been assigned to the ENVIRONMENTAL MONITORING series.
This series describes research conducted to develop new or improved methods
and instrumentation for the identification and quantification of environmental
pollutants at the lowest conceivably significant concentrations. It also includes
studies to determine the ambient concentrations of pollutants in the environment
and/or the variance of pollutants as a function of time or meteorological factors.

ABSTRACT
Aerometric data is being collected by the Regional Air Pollution
Study (RAPS) for use in developing and evaluating air quality simulation
models. In addition to the Regional Air Monitoring System (RAMS), data
is also collected by research teams in periodic expeditions to the St.
Louis study area. Data from all sources are made available for integration
through the RAPS Data Bank. A quality assurance audit of instrument
systems employed in the Summer 1975 RAPS Expeditionary Research Program
was conducted to check the various systems for accuracy. Additionally
such checks provide a basis for determining the extent to which data
from different instrument systems may be integrated. This report describes
the audit equipment and standards used and problems encountered. Quantitative
audit results from individual instrument systems are presented. The
audits included analyzers for NO, NO , 0,,, SO,,, CO, CH. and THC measurements.

1.0 INTRODUCTION
This report summarizes the preparation and use of a mobile calibration
system for the RAPS 1975 Summer Study Quality Assurance Audits. The purpose
of these audits was to check the analyzers of the RAPS field investigations
and RAMS stations for accuracy. A mobile laboratory van was used to carry a
controlled environment to the field. A brief description of the methods used
to acquire the data and a listing of the pertinent data is included.

3.0 WORK PERFORMED
The work performed consisted of preparing the van for mobile calibration
use, calibrating the transfer standards using National Bureau of Standards
(NBS) reference materials, and performing audits on the measurement systems
of independent investigators and selected RAMS stations.
During the performance of this task the Air Monitoring Center provided
the services of a senior engineer and a technician to perform the required
tasks. The specific calibration procedures employed and the schedule of
sites and analyzers were received from the EPA Task Coordinator, S.L. Kopczynski,
in the form of technical direction on a daily basis.
3.1 VAN PREPARATION
The van preparation included modifications to the physical support system
and installation of the instrumentation system.
3.1.1 Physical Support__System
The Winnebago van originally had a single generator for the entire vehicle
when it was not using line power. In order not to overload this generator and
to prevent surges in the instruments when the air conditioner started, another
generator was installed by EPA. This generator was only used on the air con-
ditioner with the other handling the instruments. The second generator was
wired into the system to allow either A.C. line power or the generator to power
the air conditioner (See Figure 1).
3.1.2 Instrumentation
The government supplied instruments consisted of a Bendix NO-NO,, analyzer,
a Bendix Ozone analyzer, a Tracer sulfur chromatograph and a Bendix dynamic
calibration system. These instruments were calibrated and installed in the van
with the appropriate auxiliary gases necessary for operation. The plans for
using the mobile laboratory instruments for cross-checking analyses was dropped
in favor of more thorough multipoint calibration checks which utilized all budg-
eted manpower.
3.2 CALIBRATION METHODS
The gas sources used in calibration were directly traceable to NBS where
possible. These concentrated gases were diluted to several values and a cor-
responding multipoint calibration performed on the analyzers.

3.2.1 NO-NOX Source Calibration
The mobile lab contained a tank of approximately 100 ppm of NO, which was
used as the standard for NO-NO*, calibrations. This tank was initially calibrated
using a NBS NO cylinder #RSG-30-7963 which contained 93.4 ppm as the standard
reference. This calibration was done in the GC lab using a Bendix NO-NO^ ana-
lyzer (which was calibrated with the NBS tank) to measure several known mixtures
of the unknown tank. Efforts were made to have the same concentrations as those
used in the initial calibration of the instrument.
3.2.2 S02 Source Calibration
Two NBS S02 permeation tubes Were used as the standard for all audits. Since
the permeation rate of the tube is highly temperature dependent, it was placed in
an oven in the Bendix Dynamic Calibrator which had provisions for both heating as
well as cooling in order to maintain a temperature of 25°C, +_ 0.1°C. The output
of the Bendix Dynamic Calibrator was cross-checked at the RAMS station 120 with an
NBS permeation tube installed in the station calibration system.
3.2.3 CO and CH4 Source Calibration
An NBS CO tank containing 9.82 ppm CO was used in conjunction with the GC
laboratory's 6800 to certify three Scott tanks, one containing a 21.2 ppm of
CO (#11722), one containing 2.01 ppm CH4 and 5.24 ppm CO (#1749) and one con-
taining 2.04 ppm CH. and 5.20 ppm CO (#2359). These tanks were either used direct-
ly to give a single point or dynamically diluted with either Matheson zero air or
Scott ultrapure air to give a multipoint calibration. The zero air was also
checked for residue CO and was found to be within acceptable tolerances.
3.2.4 03 Source Calibration
The Oo used for the audits was generated on site through use of a uv tube
which was assumed to have adequate short term stability but would vary from day to
day. For this reason the 03 output was calibrated each time the 03 was used by
means of an 03 - NO titration immediately after calibration of an NO-NOX analyzer.
Since the instrument's calibration could be traced to a NBS NO tank, the drop in NO
when the 03 was turned on gave a calibrated 03 value at that flow setting. Others
were obtained by varying the dilution flow for a multipoint calibration.
-5-
-------
3.3 INSTRUMENT CALIBRATION METHOD
The calibration system employed was a Bendix Dynamic Calibrator which used
precision pressure regulators to maintain a given pressure differential across
sets of capillaries which in turn would give a constant flow. These flows were
calibrated for various pressure settings using a bubble meter at the beginning
of the study. Near the end of the study, a bubble meter and mass flow meters
#FM-302 and FM-300 were used to recalibrate Input C capillary #4 and check the
others.
There are three pressure regulators; one controls the flow across the per-
meation oyen which has two flow levels - a high flow and a low flow. The second
controls the flow of concentrated calibrating gas to be diluted by the zero air
from the third regulator. The third regulator has four capillaries associated
with it for generating a wide range of dilutions. Air from one of these capil-
laries flows through an ozone generator and is used, for NOp checks via gas phase
titration and to calibrate the ozone analyzer (Figure 2).
The gas mixture produced by this method was introduced into a glass manifold
to produce a demand system operating at atmospheric pressure. Before the arrival
of the manifold, a simple Tee was used, this was found to effect the sample flow
rate of some instruments at the lower concentration levels. A complex Tee arrange-
ment removed this bias, no data was taken under the simple Tee arrangement. The
RAMS stations internal calibration manifold was used when auditing stations. In
all cases, the inter-connections were made with Teflon tubing and fittings.
3.4 PREPARATION OF CALIBRATION CURVES
The same procedure was used on all instruments to prepare calibration curves.
This procedure consisted of generating various gas concentrations and allowing the
instrument to sample them until the instrument equilibrated before a reading was
taken. This reading along with the known concentration was tabulated and a least
squares linear fit was used to find an intercept and a slope. All instruments
were done this way including the NO-NO., instrument used in finding the ozone con-
centration. This procedure assumes all of the flows are correct as well as the
concentration of the tank gases and the zero air was pure. The dilution or zero
air used was bottled zero air for areas other than RAMS stations with the station

3.5 AUDIT SITES
The main thrust of the quality assurance audits were to check analyzers of
RAPS field investigations and RAMS for accuracy. Several RAMS stations were
checked. In particular, stations 113 and 122 were selected because unusually
high ozone concentrations were consistently obtained there.
The data from each of the sites are presented in a standard format in Tables
1-22. For each case the column "data reading" contains the observed instrument
response in volts; "Calibrator Value" is the known concentration (ppm) which was
supplied to the instrument; "Station Value" is the concentration (ppm) calculated
from the voltage response and the calibration constants in use for that instru-
ment at that time.
A summary of results is presented in Table 23. The percent error was cal-
culated by subtracting the calibration value from the station value (at the high-
est point), dividing by the calibrator value and multiplying by 100. The sig-
nificance of the table is in that it demonstrates a rough confidence factor in
measurements of this type.
3.5.1 RAPS Helicopters
The RAPS helicopter site was audited three times. There was only enough time
to audit one of the three helicopters each visit. The first visit was not
successful due to malfunction of the calibration instruments. The Bendix cal-
ibrator has several pull-to-test gas line diverters for calibration purposes, one
of which had worked loose and shut off a main capillary flow. With this flow shut
off, it was impossible to calibrate all instruments. The results are in Tables
1-3.
3.5.2 Meteorology Research Incorporated Plane (MRI)
The MRI plane was audited twice in the Thunderbird hangar at Spirit of St.
Louis Air Field. The temperature of the permeation bath was not performing
correctly during the first audit. The temperature of the Bendix permeation oven
is adjusted by a multi turn pot. In the process of moving, a wire was dislodged
from this pot resulting in a much higher temperature than indicated by the set-
ting of the pot. This wire was repaired and the setting was returned to 25°C.
-8-
-------
There was some question of this setting by MRI on the second visit since their
value did not agree to the standard. The system was rechecked in station 120
and the setting was still found to be 25°C with a thermometer traceable to NBS.
The results are in Tables 4-6. (NO, S02 data for first visit).
3.5.3 Aerosol Trailer
The aerosol trailer located west of Glasgow, Illinois was visited twice.
The first time the aerosol trailer had some grounding problems on the inputs which
affected many of the readings, in particular the 0- reading gave a very poor linear
fit. Since there wasn't any way to decide which values were valid, all values
were reported. The results are in Tables 7-9.
3.5.4 Research Triangle Institute Van
The 6800 on the RTI was audited once for CO values. The values are in Table
10.
3.5.5 Environmental Measurements Incorporated Van (EMI)
The EMI van associated with the MRI plane was audited during the second
visit to the plane. The van was located outside the Thunderbird hangar and the
calibration took place outdoors since the air conditioner of the mobile labora-
tory was not operational. The sulfur reading was high; however, upon checking
the Bendix System later in Station 120 the temperature was still found to be
25°C. During the audit of the van the indicator for heating or cooling was
steady on the cooling side; this may have represented an inability of the cool-
ing unit to keep the permtube at the proper temperatures.
The EMI calibrator was checked and found to give proper readings; however,
the van was not available for further checking. The results are in Tables 11-12.
3.5.6 RAMS Stations
The stations checked were 120, 105, 113 and 122. The permeation tubes
were found to be off in 105, 113 and 120. In order to check the station perm-
tube with a NBS standard, the NBS tube had to be placed in the station approx-
imately 24 hours before the audit to equilibrate. Due to the large distance and
time factor for station 122, this could not be done in time to check the station
tube. Station #113 and 122 were checked mainly for 03 values. The values are
-9-
-------
found in Tables 13-19.
3.5.7 Lou Cheney's 0-, and CO Monitors
Two portable 03 monitors were used in a series of experiments. These were
compared twice with 03 analyzers at RAMS station 105, A CO monitor was also
used in this experiment. Several bag samples as well as dynamic diluted samples
were tested on this instrument. The results of the first audit are presented
in the Tables. During the second audit, there appeared to be a problem with the
6800 in station 105 which gave conflicting results. This was later found to be
caused by the automatic range switching program. A test in the G.C. laboratory
cleared this up. The 0^ monitors during the second audit were off by as much as
30%. Questions arose as to the reliability of the NO NBS tank, Central's NBS tank
and the working standard NO tank. A Bendix NO-NO,, instrument was connected to
the Bendix dynamic calibrator and the various tanks were then compared by means
of the NO-NOY instrument. A difference in the working standard tank was found
A * - '
from the original calibration, then a difference between the two NBS tanks was
found. Upon further retesting the values were not found to be repeatable since
the NO-NO instrument was drifting. Readings taken a day apart or even morning
X
versus afternoon gave a different value. The NO-NOw instrument had been on pre-
viously without the vacuum but with oxygen connected. In the past this condition
has been found to give erroneous results on some instruments for as long as 2-3
days after the vacuum has been reconnected. This may have been the problem;
however, it was not resolved in the time frame available. This is not believed
to have affected the readings of the Tables. The results are in Tables 20-22.
3.5.8 Environmental Quality Research (EQR) Theta Sensor
As a service to EQR a Theta sulfur sensor was calibrated using the stations
calibration system with a NBS permeation tube. EQR inadvertantly readjusted the
settings and the instrument was recalibrated in a similar fashion.
3.5.9 Battelle Northwest DC-3
Battelle Northwest employed a portable sulfur gas chromatograph (AID)
-10-
-------
(model #513) for the Metromex study. As a courtesy the gas chromatograph was
calibrated for S0? on a visit to the Battelle plane at the Alton City Airport.
3.5.10 Gas Chromatography Laboratory
The Gas Chromatography Laboratory was not audited. However, cylinder
no. 1749 (Section 3.2.3) with its certified analysis, was used as the daily
calibration standard for the Beckman 6800 gas chromatograph.
3.6 RAW DATA
The raw data was placed in two laboratory notebooks with carbon copies.
They were turned over to the EPA Task Coordinator.
-11-
-------
4.0 PROBLEMS AND RECOMMENDATIONS
Most of the problems encountered during the audits were caused by lack of
feedback from the calibrator. There was no flow indicator or temperature indica-
tor. A pressure was set on the regulator and it was assumed the flow was correct.
The lack of a temperature indicator required the entire permeation oven to
be taken apart in order to place a thermometer in the cavity to register the
temperature. The permeation tube in the meantime would change temperature and
require a settling time on the order of hours before it would register correctly.
A higher setting of the temperature to 30°C would give a temperature which would
be easier to maintain in a high temperature ambient environment such as was en-
countered in the study.
The calibrator did not have a calibration manifold attached to it, this re-
quired an additional manifold to be carried each time there was a non-RAMS
station field use. The problem from a lack of a calibrator manifold was en-
countered early in the program when high dilution flows caused a pressure build-
up in the sampling line which caused the instrument sample flow to increase.
A portable calibrator with direct reading mass flow meters, or even
rotameters along with an actual temperature indicator instead of a null de-
tector, would solve many of these problems.

16. ABSTRACT
Aerometric data is being collected by the Regional Air Pollution Study
(RAPS) for use in developing and evaluating air quality simulation models. In
addition to the Regional Air Monitoring System (RAMS), data is also collected by
research teams in periodic expeditions to the St. Louis study area. Data from
all sources are made available for integration through the RAPS Data Bank. A
quality assurance audit of instrument systems employed in the Summer 1975 RAPS
Expeditionary Research Program was conducted to check the various systems for
accuracy. Additionally such checks provide a basis for determining the extent
to which data from different instrument systems may be integrated. This report
describes the audit equipment and standards used and problems encountered.
Quantitative audit results from individual instrument systems are presented.
The audits included analyzers for NO, NO , O
3'
co,
CH and THC measurements.
