     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.

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.

                          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.

                           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.

                             '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.

      to the Project Officer,  _	                .  A glass manifold and
      necessary  equipment were also provided to draw the sample from the audit
      cylinder for your convenience.

           Please note that these cylinders have been analyzed several times and
      are very valuable.  We urge you to use only the amount of gas required to
      conduct the audit of your analytical system and return the cylinders and all
      the equipment (glass manifold etc.) sent to you as soon as possible so that
      other organizations may also participate in the audit program.  I am re-
      questing that you submit the audit results to the Project Officer or to me
      and ship the cylinders and all other equipment back to Research Triangle
      Institute, Building #6, Post Office Box 12194, Research Triangle Park, North
      Carolina 27709, within 15 days of the date of delivery at your  cost.  We
      would appreciate your cooperation in this regard.

        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.

-------
     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.

  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.
