FOREWORD
Source measurement and monitoring efforts are designed to anticipate
potential environmental problems, to support regulatory actions by develop-
ing data bases needed in developing regulations and to provide means of mon-
itoring compliance with regulations. The Environmental Monitoring Systems
Laboratory, Research Triangle Park, North Carolina, has the responsibility
for implementation of agency-wide Quality Assurance programs for air pollu-
tion measurement systems; and supplying technical support to other groups in
the Agency including the Office of Air and Radiation, the Office of Toxic
Substances, and the Office of Enforcement.
The need for reliable standards for auditing and documenting the accu-
racy of source emission measurement of organic hazardous pollutants is well
established. The Quality Assurance Division of EPA's Environmental Monitor-
ing Systems Laboratory has responded to this need through the development of
an extensive repository of gaseous organic compounds in parts-per-billion
(ppb) levels in compressed gas cylinders. The primary objectives of this
on-going project are (1) to provide accurate gas mixtures to EPA, state/
local agencies, or their contractors for performance audits to assess the
accuracy of source measurement systems during hazardous waste trial burn
tests and ambient air monitoring programs; (2) to verify the manufacturer's
certified analysis of the multi-component gas mixtures, (3) to determine the
stability of the gas mixtures with time, and (4) to develop new audit mater-
ials as requested by EPA. This report describes the current status of this
project. Included in the report are (1) a description of the experimental
procedures used for the analyses of multi-component ppb level gas mixtures;
(2) a description of the audit procedure, and (3) currently available audit
results and stability data.

ABSTRACT
A repository of 22 gaseous organic compounds at parts-per-billion (ppb)
levels in compressed gas cylinders has been established under a contract
with the Environmental Protection Agency (ERA). The primary objectives of
this on-going project are: (1) to provide accurate gas mixtures to EPA,
state/local agencies, or their contractors for performance audits to assess
the relative accuracy of source measurement systems during hazardous waste
trial burn tests and ambient air monitoring programs; (2) to verify the man-
ufacturer's certified analysis of the multi-component gas mixtures; (3) to
determine the stability of the gas mixtures with time; and (4) to develop
new audit materials as requested by EPA.
The repository consists of three mixtures of five, eight and nine or-
ganic compounds each. These mixtures were blended by a commercial gas sup-.
plier in aluminum cylinders in a balance gas of nitrogen. The five compon-
ent mixture (Group 1) contains carbon tetrachloride, chloroform, perchloro-
ethylene, vinyl chloride and benzene. The nine component mixture (Group 11)
includes trichloroethylene, 1,2-dichloroethane, 1,2-dibromoethane, acetoni-
trile, trichlorofluoromethane (F-ll), dichlorodifluoromethane (F-12),
bromomethane, methyl ethyl ketone and 1,1,1- trichloroethane. The eight
component mixture (Group 111) includes pyridine, vinylidene chloride, 1,1,2-
trichloro 1,2,2-trifluoroethane (F-113), 1,2- dichloro 1,1,2,2-tetrafluoro-
ethane (F-114), acetone, 1,4-dioxane, toluene, and chlorobenzene. To date
41 performance audits have been initiated and 35 are complete. The results
of these audits and a description of the experimental procedures used for
analyses and available stability data are presented in this status report.
Generally, the results of the audits show reasonable agreement (plus or
minus 50 percent) with the audit material concentrations measured by
Research Triangle Institute, considering the low concentrations of the
organics and the anticipated uncertainty associated with independent
analyses conducted by an audit laboratory.
Stability studies for all Group 1 and Group 11 compounds have been per-
formed. Results indicate that all the compounds tested are adequately sta-
ble for use as reliable audit materials. The Group 111 compounds will not
be available for audits until stability of the compounds has been establish-
ed. If the data indicate that the Group 111 compounds are stable, Group 111
mixtures should be available for audits on or after December 1, 1985.

INTRODUCTION
OBJECTIVES
The application of Quality Assurance practices is important to the gen-
eration of high-quality environmental data. The Quality Assurance Division
of EPA's Environmental Monitoring Systems Laboratory has initiated a program
to supply audit materials for use during hazardous waste trial burn tests
and ambient air measurements. The Research Triangle Institute (RTI), under
contract to the U.S. Environmental Protection Agency (USEPA), has responded
to this need through development of a repository of 22 gaseous organic com-
pounds at parts-per-billion (ppb) levels in compressed gas cylinders. The
main objectives of this project are: (1) to provide accurate gas mixtures to
EPA, state/local agencies, or their contractors for performance audits to
assess the relative accuracy of source measurement systems during hazardous
waste trial burn tests and ambient air monitoring programs; (2) to verify
the manufacturer's certified analysis of the multi-component gas mixtures;
(3) to determine the stability of the gas mixtures with time; and (4) to
develop new audit materials as requested by EPA.
This report describes the current status of the project. Included in
the report are: (1) a description of the experimental procedures used for
the analyses of multi-component ppb level gas mixtures; (2) a description of
the audit procedure; and (3) currently available audit results and stability
data.
AUDIT MATERIALS CONTAINED IN THE REPOSITORY
The repository currently contains 22 compounds selected on the basis of
anticipated needs of EPA's Office of Solid Waste. Table 1 lists the 22 com-
pounds, the concentration ranges, and the number of cylinders for each group
in the repository. Group I cylinders each contain five (5) compounds.
Group II cylinders each contain nine (9) compounds. Group III cylinders
each contain eight (8) compounds. The audit cylinders generally fall into
two concentration ranges with one exception. Each compound in the low con-
centration range is between 7 and 90 parts-per-billion (ppb) and in the high
concentration range each compound is between 90 and 430 ppb. Twelve new
-------
audit cylinders containing Group 1 compounds in the range of 430-10,000 ppb
of each compound were recently added to the repository. The balance gas for
all gas mixtures is nitrogen, and the cylinder construction material is alu-
minum.

SECTION 2
EXPERIMENTAL PROCEDURES
Accurate analyses of the cylinder gases are required, (1) to verify the
concentrations reported by the specialty gas company that prepared the gas
mixtures, and (2) to assess the long-term stability of the concentrations of
the compounds.
INSTRUMENTATION
Analyses of Group I and II mixtures are performed using a Hewlett-
Packard 5880A gas chromatograph equipped with flame ionization and electron
capture detectors. The electron capture detector (ECD) has been used prin-
cipally for measurement of all the halogenated hydrocarbons except vinyl
chloride. Vinyl chloride, benzene, methyl ethyl ketone and acetonitrile are
analyzed with a flame ionization detector (FID). The gaseous samples are
injected onto the columns by means of a high-speed six-port gas sampling
valve (Seiscor valve Model AN 100A) mounted near the injection port. The
valve is equipped with interchangeable sampling loops (1 cc and 10 cc) to
allow the precise injection of known volumes of the gas mixtures. A sche-
matic of the gas chromatographic system is shown in Figure 1.
The gas chromatographic parameters used in the measurement of individu-
al compounds in Group I and Grouo II are listed in Table 2. The gas chroma-
tographic parameters for the Group III compounds have not yet been estab-
lished. The development of cryofocusing on capillary column for the analy-
sis of Group III compounds is in progress and the details will be presented
in a future report.
CALIBRATION
Calibration of the gas chromatograph involves measurement of known con-
centrations of organic gases in nitrogen. A custom-designed permeation sys-
tem (Figure 2) which produces known concentrations of organics in nitrogen
is used for calibration. Permeation tubes purchased from commercial sup-
pliers are generally used as calibration standards for 14 organic compounds
unless otherwise specified. Generally, two to five permeation tubes at a
time are placed in a temperature-controlled chamber (30.0 _+ O.l'C) and pure

nitrogen is passed over the permeation tube at a known flow rate using Tylan
mass flow controllers. The resultant gaseous mixture is further diluted, if
necessary, by addition of nitrogen to the mixing chamber. The final gas
mixture is removed from the permeation system (via a 3/16 inch SS line) by a
metal bellows pump located downstream from the sampling loop. No interfer-
ence was observed by keeping the number of tubes in parallel in the chamber
at a time. Cross-contamination of the tubes does not occur as long as cham-
ber flow of approximately 150 cc/min or more is maintained.
The permeation rate of each permeation tube is determined every 15 to
30 days by weight-loss determination of each tube. Permeation rates are
checked both before and after analysis and the average of the last three
values wece used for rate determination. The permeation rate data obtained
for each compound are included in Appendix C. Clean nylon gloves and tweez-
ers are used to handle the permeation tubes. The permeation tubes are re-
moved from the permeation chamber one at a time for weighing to avoid pick-
up of moisture.
In order to avoid calibration errors associated with non-linear detec-
tors (for example, ECD) at least two calibration standards are prepared each
time a sample is analyzed. Both standards are prepared usually within 20
percent of the expected sample concentration. For analysis using FID, stan-
dard concentrations are matched to sample concentrations to within at least
a factor of 2 and are within 20 percent at concentrations below 70 ppb. Two
to six calibration standards are analyzed on each day of sample analysis.
The calibration standards are injected both at the beginning and end of each
day to check for instrumental drift.
SAMPLE ANALYSIS PROCEDURE
Figures 1 and 2 depict the entire analytical system used for the cali-
bration and analysis of the gas mixtures. The analysis procedures used for
the sample analysis are as follows: Initially the samole loops are purged
with cylinder gas sample at approximately 27 cc/min for 2 minutes before in-
jection. Whenever a 10 cc loop is used, it is purged with cylinder gas for
an additional 2 minutes before injection onto the column. Sample gas flow
is controlled by slowly opening the needle valve attached to the tank. Af-
ter purging the loop, the gas flow is shut off at the needle valve. Four
-------
seconds after a flowmeter registers zero flow through samole loop, injection
is made manually onto the column. The first injection of sample or standard
is not considered quantitative, but instead is used to condition stainless
steel lines and valves. Triplicate injections of the sample are made to de-
termine the measurement precision. Generally, the measurement precision is
within 3 percent.
QUALITY CONTROL PROCEDURES
Certain quality control procedures are followed, for example, equili-
brating the permeation system before taking an aliquot for GC measurement.
A set. of primary standards for Group I and Group II multicomponent mixtures
are analyzed each day cylinder gases are analyzed to verify the constancy of
the detector response. The Group I and Group II primary standards were pre-
pared and analyzed by the National Bureau of Standards (NBS) as part of an
Interagency Agreement with EPA. NBS primary standards were not available
for the RTI first and second analyses of Group II compounds shown in Appen-
dix A (Stability Study). However, NBS primary standards were used for the
third and all subsequent Group II stability analyses. RTI results for Group
I and Group II NBS primary standards are included in Appendix A. Generally,
RTI analysis results for the NBS primary standards are within 10-percent of
the NBS analysis results. If results vary by more than 10 percent, a cali-
bration error is assumed, and the permeation system and sample valves are
checked for leaks/under both positive and negative pressure. Leak detection
fluid is used to check for leaks under positive pressure. Freon is used to
check the leaks under negative pressure. This was done by monitoring the
freon peak on the GC. Once all fittings are leak tight, recalibration of GC
is performed. Blank measurements are taken during cylinder analysis and
generally, blank measurements have shown no signal above the baseline.

SECTION 3
PERFORMANCE AUDITS
The RTI supplies repository cylinders for audits upon request from the
EPA, state or local agencies or their contractors. A contractor must be
performing hazardous waste trial burn tests or ambient air measurements at
the request of EPA, a state or local agency in order to qualify for the per-
formance audit. When a request is received, the tank pressures are measured
and the cylinders are shipped by overland carrier. An aluminum suitcase
containing a gas regulator, a heated glass manifold and the necessary tubing.
and fittings to draw the cylinder gas sample into the glass manifold is also
provided for drawing the audit gas through the VOST system. A schematic of
this audit gas delivery system is shown in Appendix B, Figure 1. A letter
is included with the audit cylinder which gives general instructions for
conducting the audit (see Appendix B). Detailed instructions are shown in
Appendix B on how to conduct an audit of VOST (Instruction No. 3) and bag
measurements (Instruction No. 1) during a hazardous waste trial burn. The
audit gas concentration for each compound and cylinder gas pressure are pro-
vided to the requesting agency audit coordinator. There is no charge for
the audit except the cost of returning the audit cylinder.
To date, 41 performance audits have been initiated; 36 are complete.
The sampling and analysis methods used by auditees during performance audits
are summarized in Table 3. The audit results currently available are pre-
sented in Table 4. The audit results are usually within +_ 50 percent of the
audit concentrations measured by RTI.

SECTION 4.0
'STABILITY STUDIES
An ideal calibration standard or audit material should be stable over
its total time of usage. It may be concluded that such standards or materi-
als are stable if reanalyses over time do not exceed the total uncertainty
of the analyte concentrations at the 95 percent confidence limits.
On this project, the gas mixtures were analyzed twice by the manufac-
turer before shipment to RTI. These analyses were performed to demonstrate
that the components in the cylinder were stable at the manufacturer facility
before shipment to RTI. The gas mixtures are then analyzed at RTI upon re-
ceipt from the specialty gas vendor to corroborate the vendors's analysis.
The gas mixtures are again analyzed at 2 months, 6 months, 12 months and 18
months following the initial RTI analysis to determine the stability of the
gas mixtures. The results of the analyses of the manufacturer, RTI and N8S
primary standards are summarized in the stability data tables shown in Ap-
pendix A.
Relative accuracies of the cylinder gas analyses for Group I and Group
II compounds have been determined using NBS primary standards on each day of
RTI analysis. The method used by NBS to estimate the total uncertainty of
NBS primary standards at the 95 percent confidence level has been reported.
The analysis results along with the total uncertainty at 95 percent confi-
dence limits for Group I and Group II compounds are included in the stabili-
ty data tables in Appendix A. These primary standards have been assessed
for stability by NBS and no change in concentrations have been observed that
have exceeded the 95 percent uncertainties of the concentrations. Also, NBS
still maintains a continued QA program on these primary standards in which
reanalyses are conducted over time to verify that the concentrations have
not changed.
An examination of the stability data in Appendix A shows values for
Group I and Group II cylinders usually vary by less than 10 percent for 4 or
5 analyses over a 1-year period. This variation indicates the imprecision
of the measurement process. The possible sources of experimental error that
contribute to this variability include: (1) the variability of the sampling
injection technique used for analyses; and (2) the instrumental variability
30
-------
in operating and detector parameters. Each of these sources of variability
contributes to the net uncertainty of the resulting data presented in Appen-
dix A. The procedures used for the determination of day- to-day measurement
uncertainty (repeatability) for Group I and Group II compounds have recently
been published.^ Estimates of total uncertainty (repeatability) for Group I
compounds have been determined to be in the range of 2.1-3.2% (coefficient
of variation) at 95% confidence limits. The estimate of total uncertainty
for Group II compounds have been determined to be in the range of 3.4-7.0%
(coefficient of variation) at 95% confidence limits.

SUMMARY AND CONCLUSIONS
A repository of 14 gaseous organic compounds at parts-per-billion lev-
els in compressed gas cylinders has been used successfully in audits to as-
sess the relative accuracy of analytical systems, especially those used dur-
ing hazardous waste trial burn tests and ambient air monitoring. The repos-
itory consists of three mixtures of five, eight and nine organic compounds
each. These mixtures were blended by a commercial specialty gas supplier in
aluminum cylinders in a balance gas of nitrogen. The five component mixture
(Group 1) contains carbon tetrachloride, chloroform, perchloroethylene,
vinyl chloride and benzene. The nine component mixture (Group 11) includes
trichloroethylene, 1,2-dichloroethane, 1,2-dibromoethane, acetonitrile,
trichlorofluoromethane (F-ll), dichlorodifluoromethane (F-12), bromomethane,
methyl ethyl ketone and 1,1,1-trichloroethane. The eight component mixture
(Group 111) included pyridine, vinylidene chloride, 1,1,2-trichloro 1,2,2-
trifluoroethane (F- 113), 1,2-dichloro 1,1,2,2- tetrafluoroethane (F-114),
acetone, 1,4-dioxane, toluene, and chlorobenzene.
Stability studies for 14 compounds (Group 1 and Group 11) have been
performed to determine the feasibility of using them as audit materials.
Results indicate that all of the organics tested are adequately stable to be
used as reliable audit materials. The Group 111 compounds will not be
available for audits until stability of the compounds have been established.
If the data indicates that the Group 111 compounds are stable, Group 111
mixtures should be available for audits on or after December 1, 1985.
Subsequent to completion of the stability studies, 41 performance
audits have been initiated to date with Group 1 and Group 11 cylinders and
36 are complete. Generally, the audit results are within +_ 50 percent of
the audit concentrations measured by RT1.

INSTRUCTIONS FOR THE SAMPLING AND ANALYSIS OF VOLATILE POHC
FROM QUALITY ASSURANCE AUDIT CYLINDERS USING THE BAG TECHNIQUE
1.0 PURPOSE
This audit is intended to assess and document the accuracy and preci-
sion of the principle organic hazardous constituents (POHC) using the bag.
technique during trial burns at hazardous waste burning facilities. This
audit also can be used to determine the proficiency of source testing organ-
ization prior to the actual trial burn tests.
2.0 PRINCIPLE
A gas sample containing POHC is drawn from an audit gas cylinder into a
bag. The collected POHC are analyzed by gas chromatography according to the
method specifications and procedures.
3.0 AUDIT MATERIAL (GAS CYLINDERS)
The audit material is contained in gas cylinders. A maximum of 5 L of
audit gas is to be used for each test run. A two-stage gas regulator,
1/4-inch male/female glass joints, and Teflon® tubing are supplied for use
with the gas cylinder.
4.0 PROCEDURES
The following step-by-step procedures should be used for sample collec-
tion and analysis using the bag technique.
Step A. Evacuate the bag with a vacuum pump and fill the bag with
approximately 5 L of organic-free nitrogen from a gas cylin-
der. Tedlar® bags are recommended. Determine the hazardous
constituents of interest by gas chromatography. Report the
concentrations determined as Blank Value 1. The blank value
must be not more than twice the detection limit. If it is
higher, the bag cleaning procedure should be repeated.
Step B. After the blank analysis, evacuate the bag with a vacuum pump
and fill the bag with approximately 5 L of audit gas from the
audit cylinder. The 1/4 inch male/female glass joints that
are supplied should be used as connections to the bag and the
audit cylinder. Minimum Teflon® tubing should be used. De-
termine the POHC of interest by gas chromatography. Report
the concentrations of each constituent as Analysis Result 1.
B-3
-------
Step C. Evacuate the bag contents and fill the bag with organic free
nitrogen (Cleaning Step 1). After 3 minutes, evacuate the bag
contents and fill .the bag again with nitrogen (Cleaning Step
2). After three minutes, repeat the evacuation procedure and
fill the bag with 5 L of nitrogen (Blank 2). Determine the
concentration of the bag contents by gas chromatography and
report the measured concentration as Blank Value 2. The blank
value must not be more than twice the detection limit. If it
is higher, the' bag cleaning procedure should be repeated.
Step D. Evacuate the bag contents and fill the bag with approximately
5 L of audit gas from the audit cylinder. Determine the POHC
of interest by gas chromatography. Report the concentrations
determined as Analysis Result 2.
Step E. Repeat Step C and report the measured concentration of the bag
contents as Blank Value 3. The blank value must not be more
than twice the detection limit. If it is higher, the bag
cleaning procedures should be repeated.
Step F. Evacuate the bag contents and fill the bag with approximately
5 L of audit gas from the audit cylinder. Determine the POHC
of interest by gas chromatography. Report the concentrations
determined as Analysis Result 3.
5.0 SAMPLE ANALYSIS
Follow the procedures described in the method used for sample analysis,
calibration, and calculations. Submit the results to the Project Officer and
to the audit supervisor for evaluation.

INSTRUCTIONS FOR THE SAMPLING AND ANALYSIS OF VOLATILE POHC FROM QUALITY
ASSURANCE AUDIT CYLINDERS USING THE VOLATILE ORGANIC SAMPLING TRAIN
1.0 PURPOSE
This audit is intended to assess and document the accuracy and pre-
cision of the volatile organic sampling train (VOST) when used during trial
burns at hazardous waste burning facilities. This audit also can be used to
determine the proficiency of source testing organization prior to the actual
trial burn tests.
2.0 PRINCIPLE
A gas sample containing principal organic hazardous constituents
(POHC) is passed from an audit gas cylinder into a glass manifold and is
used in place of the test site stack sample. While the POHC gas is being
passed into the glass manifold, a major portion of the gas is drawn through
a VOST according to the method specifications and procedures. The collected
POHC are analyzed by thermal desorption, purge and trap, and gas chroma-
tography/mass spectrometry (GC/MS) or an equivalent method approved by the
EPA.
3.0 APPARATUS
3.1 . GLASS MANIFOLD
A glass manifold is supplied. One side of the glass manifold is con-
nected with Teflon® tubing to the audit cylinder. The other end of the
glass manifold should be connected with Teflon® tubing to a rotameter and
the excess gas from the rotameter should be vented into a hood. The glass
manifold is heated to 100°C with heating tape. The heating tape, rotameter,
1/4-inch male/female glass joints, and Teflon® tubing are also supplied.
One port of the glass manifold should be connected to the VOST probe with
1/4-inch male/female glass joints. A schematic diagram of the glass mani-
fold is shown in Figure 1.
3.2 VOST COMPONENTS
The sampling train component parts, except for the glass manifold, are
the same as those used for VOST,

3.3 ANALYSIS
Refer to the method specifications and procedures for the VOST
method.
4.0 AUDIT MATERIAL (GAS CYLINDERS)
The audit material is supplied in gas cylinders. A maximum of 50
L of gas is to be used for each test run. A two-stage gas regulator is sup-
plied for use with the gas cylinder.
5.0 PROCEDURES
5.1 SAMPLING
5.1.1 Preparation of VOST
All train components should be cleaned and assembled as described in
the VOST method used.
5.1.2 Leak-Check Procedure
Before the sampling run, the train is leak-checked as described in the
VOST method. During sampling, all connections should be visually ex-
amined.
5.1.3 Sample Generation
The gas sample from the audit cylinder is passed through the glass
manifold at a flow rate of 2 L/min for 3 minutes to condition the glass sys-
tem. A glass rotameter is supplied to measure the flow rate at the end of
the glass manifold. The VOST probe then should be connected to one port of
the glass manifold with 1/4 inch male/female joints and the probe should be
purged with audit gas for an additional 2 minutes so that the probe is
purged of ambient air before initiation of sample collection. This can be
accomplished either by attaching a pump to a three-way stop-cock above the
first condenser and drawing audit gas through the probe via the three-way
stop-cock or by any other suitable method.
5.2 SAMPLE COLLECTION
After leak-checking and conditioning the glass probe, sample collec-
tion is accomplished by opening the valve at the inlet to the first conden-
B-7
-------
ser, turning on the pump and sampling at a rate of 0.5 L/min for 20 minutes.
The sampling rate is measured with the rotameter wh-ich is part of the VOST.
The volume of sample for any pair of the traps should not exceed 10 L. The
temperature of the gas stream at the inlet to the first sorbent cartridge
must be maintained at 20*C during sample collection.
After the collection of 10 L of sample, the train is leak-tested using
•the procedures described in the method used. If leak-test criteria as
described in the method are not met, the samples should not be analyzed. If
leak-test criteria are met, the train is returned to atmospheric pressure,
the two sorbent cartridges are removed, the end caps are replaced, and
analysis of cartridges is performed.
Repeat the sample collection procedure two more times with two new
pairs of sample cartridges in the VOST, collect 10 L of sample each time,
and perform the analysis.
5.3 SAMPLE ANALYSIS
Follow the procedures described in the method for sample analysis,
calibration, and calculations. Report the amount of each constituent in the
three samples and the blank values to the Project Officer and the audit
supervisor for evaluation.

INSTUCTIONS FOR USE OF VOST AUDIT KIT
1. Attach the supplied tubing to the manifold according to the diagram
shown in Figure 1. (See page 66.)
2. The manifold and rotometer should be secured to the support stand
with the clamps provided in the kit. Most situations will require
the manifold to be mounted vertically with the inlet at the bottom,
and parallel to the rotometer. Allow the short 3/8" O.D. tubing to
loop around to the bottom of the rotometer, without introducing any
sharp kinks which may restrict the gas flow.
3. Gently pull the electrical cords from their compartment and connect
according to the. diagram on the reverse. The nominal length for
the 110 VAC power cord is 8 feet and the nominal length for the
output cord is 6 feet.
4. Temporarily remove the short 3/8" tubing from the outlet end of the
manifold and insert the dial thermometer into the manifold. Adjust
the variable transformer, which is mounted in the case, to heat the
manifold to approximately 100°C. A setting of 50 on the scale
should be sufficient to attain 100°C. After the manifold tempera-
ture has become stable, remove the thermometer and reattach the
3/8" tubing.
5. Adjust the regulator to start gas flow. The rotometer is down-
stream of the manifold and should be used to regulate the excess
gas flow from the manifold. Approximate flow rates at COB are
given below:
Gas Flow Center of Ball
1.0 STD L/min 12.7
1.3 15.0
1.9 20.0
2.5 24.7
3.0 28.7
3.2 30.0
3.5 32.7
The rotometer will present negligible back pressure to the mani-
fold. AP for 5 L/min is 1 inch of water column.
6. After sampling is completed,' allow the manifold to cool, disas-
semble and repackage the kit in the case. Gently push the power
and output cords back into their compartment. Remove the knob from
the regulator to facilitate packing in its' compartment.
