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 compressed gas cylinders containing gaseous organic compounds in parts-per- billion (ppb) levels. The primary objectives of this on-going project are (1) to evaluate the quality of measurements made by EPA, state/local agen- cies, or their contractors, by using ppb gas cylinders for performance au- dits 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 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. Gary 0. Foley.Ph.D. Director Environmental Monitoring Systems Laboratory Research Triangle Park, Nortn Carolina ------- ABSTRACT The U.S. Environmental Protection Agency (USEPA) has evaluated the suitability of 29 gaseous organic compounds at parts-per-billion (ppb) lev- els in compressed gas cylinders for use as audit materials during hazardous waste trial burn tests and ambient air measurements. The primary objectives of this on-going project are: (1) to evaluate the quality of measurements made by USEPA, state/local agencies, or their contractors by using ppb gas cylinders for performance audits during hazardous waste trial burn tests and ambient air monitoring programs; (2) to verify the manufacturer's certified analyses 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 USEPA. The cylinders consist of five mixtures of five, six, eight, nine, and eighteen organic compounds each. These mixtures were blended by a commer- cial gas supplier in aluminum cylinders in a balance gas of nitrogen. The five-component mixture (Group I) contains carbon tetrachloride, chloroform, tetrachloroethylene (perchloroethylene), vinyl chloride and benzene. The nine-component mixture (Group II) includes trichloroethylene, 1,2-dichloro- ethane (ethylene dichloride), 1,2-dibromoethane (ethylene dibromide), aceto- nitrile, trichlorofluoromethane (F-ll), dichlorodifluoromethane (F-12), bromomethane (methyl bromide), methyl ethyl ketone and 1,1,1-trichloro- ethane. The eight-component mixture (Group III) includes pyridine*, vinyl- idene chloride, l,l,2-trichloro-l,2,2-trifluoroethane (F-113), 1,2-dichloro- 1,1,2,2-tetrafluoroethane (F-114), acetone, 1,4-dioxane, toluene, and chlorobenzene. The six-component mixture (Group IV) includes acrylonitrile, 1,3-butadiene, ethylene oxide, methylene chloride, propylene oxide, and o-xylene. The eighteen-component mixture (Group V) includes vinyl chloride, 1,3-butadiene, bromomethane, trichlorofluoromethane (F-ll), methylene chloride, chloroform, 1,2-dichloroethane, 1,1,1-trichloroethane, benzene, carbon tetrachloride, 1,2-dichloropropane, trichloroethylene, toluene, 1,2-dibromoethane, tetrachloroethylene, chlorobenzene, ethylbenzene, and o-xylene. To date 198 performance audits have been initiated and 172 are *Although Group III cylinders contain pyridine, the concentrations are not certified due to severe analytical difficulties. IV ------- 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 (RTI), considering the low concen- trations of the organics and the anticipated uncertainty associated with independent analyses conducted by an audit laboratory. Quality assurance of the concentrations of the organics in Groups I - V is provided by EPA auditing of the audit laboratory (RTI) using NBS-trace- able standards for these Groups prepared by NBS under a EPA-NBS Interagency Agreement, and by the subsequent use of the NBS-traceable standards to as- sign the concentrations in the cylinders obtained from the commercial gas supplier that are used in this audit program. The NBS-traceable standards also are used by RTI to ensure quality control in reanalyses conducted over time to verify the long-term stability of the audit cylinders. Stability studies for all Group I, Group II, Group III, Group IV and Group V compounds have been performed. Results have established that all the compounds tested are suitably stable for use as reliable audit materi- als except ethylene oxide and propylene oxide at low concentrations. ------- CONTENTS NOTICE ii FOREWORD i i i ABSTRACT i v FIGURES .' i iv TABLES i i 1v 1.

The Quality Assurance Division of USEPA's Environmental Monitoring Systems Laboratory has initiated a pro- gram to supply audit materials for use during hazardous waste trial burn tests and ambient air measurements. RTI, under contract with USEPA, has responded to this need through development of cylinder gases containing 29 gaseous organic compounds at ppb levels. The main objectives of this pro- ject are: (1) to evaluate the quality of measurements made by USEPA, state/ local agencies, or their contractors, by using ppb gas cylinders for per- formance 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 over time; and (4) to develop new audit materials as requested by USEPA. 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 CURRENTLY AVAILABLE Currently, 29 gaseous compounds selected on the basis of the antici- pated needs of USEPA's Office of Solid Waste and Office of Air Quality Plan- ning and Standards have been investigated for suitability as audit materi- als. Table 1 lists the 29 organic compounds, the concentration ranges, and the number of cylinders for each group currently available in the ppb level cylinder gases. Group I cylinders each contain five (5) compounds; Group II cylinders each contain nine (9) compounds; Group III cylinders each contain eight (8) compounds; Group IV cylinders each contain six (6) compounds; and Group V cylinders each contain eighteen (18) compounds. The audit cylinders fall into three concentration ranges, depending upon the group to which the cylinder belongs. Each compound in the low concentration range is between 7 and 90 ppb and in the intermediate concentration range is between 90 and 430 ------- ppb. In addition, Group I and Group IV cylinders are available in a high concentration range between 430 and 10,000 ppb. The Group V cylinders are available in the concentration range between 1-40 ppb. The balance gas for all gas mixtures is nitrogen, and the cylinder construction material is aluminum. Table 1.

INSTRUMENTATION Analyses of Group I, II and III mixtures are performed prior to 1987 using a Hewlett-Packard 5880A gas chromatograph equipped with flame ioniza- tion and electron capture detectors. The electron capture detector (ECD) is used principally for measurement of all the halogenated hydrocarbons except vinyl chloride. The flame ionization detector (FID) is used for the analy- sis of vinyl chloride, benzene, methyl ethyl ketone,. acetonitrile, all Group III compounds, and all of the Group I compounds in the high concentration range cylinders. The gaseous samples are injected onto the gas chromato- graphic column by means of two Valco six-port gas sampling valves mounted near the injection port. One valve is equipped with interchangeable sam- pling loops (1 cc and 3 cc) to allow the injection of different volumes of the gas mixtures. A schematic of the gas chromatographic system is shown in Figure 1. A schematic of the system used for generation of calibration standards is shown in Figure 2. The gas chromatographic parameters used in the measurement of individu- al compounds in Group I, Group II and Group III are listed in Table 2. Within the past year, a new method was developed for the analysis of all the ppb level cylinder gases. This method employs automated cryogenic preconcentration with cryofocusing and flame ionization detection. Analyses of Group I, II, III, IV, and V mixtures are now performed using a Nutech automated cryotrapping apparatus configured to. a Hewlett-Packard 5880A gas chromatograph equipped with a flame ionization detector (FID). A schematic of the gas chromatographic system is shown in Figure 3. The gas chromatographic parameters used in the measurement of individu- al compounds in Group I, Group II, Group III, Group IV and Group V using this new method are listed in Table 2A. ------- Carrier Gas Inlet Vent Needle Valve High Purity, -n High Pressure Needle Valve Rotameter (Sample) GC Oven ToECD < or Nx FID GC Column Valve 2 ! ^- Sample Loop or (Standard) Permeation System PPB-Level Repository Cylinder Metal Bellows Sampling Pump (for use with Permeation System, not samples) Figure 1.

The cryogenic system described here is used now for the analyses of Groups I, II, III, IV and V. ------- CALIBRATION Calibration of the gas chromatograph involves measurement of known con- centrations of organic gases in nitrogen. A custom-designed permeation sys- tem which produces known concentrations of organics in nitrogen had been used for all previous analyses of Group I and II cylinders prior to 1987. The details of the calibrations performed using permeation tubes are described previously (3). Currently, NBS-traceable standards developed and characterized by the National Bureau of Standards (NBS) under an EPA-NBS Interagency Agreement are being used for calibration for all five groups and a similar NBS standard cylinder mixture is used for Quality Control for all the analyses with the cryogenic preconcentration system. One NBS-traceable standard is used as a calibration cylinder that is analyzed at the beginning of each analysis day and a second similar NBS-traceable standard is used as a Quality Control cylinder that is subsequently analyzed on each analysis day. SAMPLE ANALYSIS PROCEDURE Figures 1 and 2 depict the entire analytical system used for the cali- bration and analysis of the gas mixtures prior to 1987. Figure 3 depicts the analytical system that is used for calibration and analysis of the gas mixtures by automated cryogenic preconcentration with cryofocusing. All analyses are now done with this method. The procedure used for the sample analysis by this method is as follows: The gaseous sam- ple is taken from the high pressure cylinder via a one-stage high pressure regulator. Sampling rate is controlled by a mass flow controller. Sample is delivered to the cryogenic preconcentration apparatus using a six-port gas sampling valve mounted on the inside of the apparatus. A second six- port gas sampling valve is used to direct sample flow through a 1.5 cc stainless steel loop packed with 60-80 mesh glass beads. Initially, the sample loop is purged with cylinder gas sample at approximately 100 cc/min for 5 minutes. After purging the sample trap, the gas flow is shut off at the second six-port gas sampling valve. The sample trap is then cooled down to a selected temperature (approx. -150°C). Once the sample trap has reached this selected temperature, gas flow is allowed to pass through the sample trap and trapping of the gas mixture begins. After a pre-determined time, injection is made automatically onto the column by heating the sample ------- trap. The concentrated sample is then re-focused at the head of the capil- lary column for two minutes. The cryofocusing trap is then heated and the actual injection is made. Triplicate injections of the sample are made to determine the measurement precision. Generally, the measurement precision is within three percent. QUALITY CONTROL PROCEDURES On each analysis day, the cryogenic analysis system is calibrated with either a Group I, II, III, IV or V primary gas standard prepared and anal- yzed by the National Bureau of Standards as part of an Interagency Agreement with USEPA. Following the calibration, a second NBS primary gas standard is analyzed as a quality control check to verify the accuracy of the calibra- tion. These RTI quality control results are shown in Appendix A (stability study). Appendix A contains a summary table for each Group I, II, III, IV and V cylinder analyzed. Included in each summary table are the RTI stabil- ity analysis and the RTI quality control result on the day the stability analysis was conducted. 10 ------- SECTION 3 PERFORMANCE AUDITS Research Triangle Institute supplies cylinder gases for audits upon request from USEPA, state or local agencies or their contractors. A con- tractor must be performing hazardous waste trial burn tests or ambient air measurements at the request of USEPA, a state or local agency in order to qualify for the performance audit. When a request is received, the cylinder pressures are measured and the cylinders are shipped by overland carrier. When a cylinder gas is used to audit the VOST system for a trial burn test, an aluminum suitcase is also sent. The aluminum suitcase contains a gas . regulator, a heated glass manifold, and necessary tubing and fittings to draw the cylinder gas sample into the glass manifold. The audit gas is then drawn at atmospheric pressure from the manifold into 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 instruc- tions are shown in Appendix B for conducting 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 provided to the requesting agency audit coordinator. There is no charge for the audit, except for the cost of returning the audit cylin- der. To date, 198 performance audits have been initiated; 170 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. 11 ------- Table 3.

Such standards or materials may be considered stable if the results of reanalyses over time fall within the 95% confidence limits of the combined uncertainty for the preparation and analysis of the analyte concentrations. The gas mixtures were generally analyzed twice by the manufacturer before shipment to RTI. These analyses were performed to verify that the components in the cylinder were stable at the manufacturing facility before shipment to RTI. The gas mixtures are then analyzed at RTI upon receipt from the specialty gas vendor to corroborate the vendors analysis. The gas mixtures are again analyzed by RTI at 2 months, 6 months, 12 months, and on an annual basis thereafter following the initial RTI analysis to determine the long term stability of the gas mixtures. The results of the analyses of the cylinder gases by the manufacturer and by RTI, along with the results for the RTI analysis of NBS primary standards are summarized in the stabil- ity data tables shown in Appendix A. Relative accuracies of the cylinder gas analyses for Group I, Group II, Group III, Group IV and Group V 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.1 The NBS concentrations and their total uncertainties at 95% confidence limits for Group I, Group II, Group III, Group IV and Group V compounds are included in the stability data tables in Appendix A. These primary standards have been assessed for sta- bility by NBS, and no change in concentrations has been observed that has exceeded the 95% confidence limit of the concentrations. The NBS maintains a continued QA program for these primary standards in which reanalyses are conducted over time to verify that the concentrations have not changed. An examination of the stability data for the cylinders gases in Appen- dix A shows that values for the Group I, Group II and Group III compounds usually vary by less than 10 percent for 4 or 5 analyses over a 2-year peri- od. This variation includes the uncertainty of the NBS primary standards and precision of the RTI measurement process. The possible sources of 92 ------- experimental error in the measurement process that contribute to this vari- ability include: (1) the variability of the sampling injection technique used for analyses of the primary standards and the audit cylinders; and (2) the instrumental variability in operating and detector parameters. Each of these sources of variability contributes to the total uncertainty of the resulting data presented in Appendix A. The procedure used for the determination of day-to-day measurement un- .certainty (repeatability when NBS primary gas standards are used for calibration is different then the procedure used when calibration was performed with permeation devices. The total uncertainty calculation procedure when using permeation devices was described in Status Report #3.3 The total uncertainty for the measurements when calibration is with an NBS primary gas standard is arrived at by summing in quadrature the estimates of error from several sources. These sources of error include: 1. NBS uncertainties associated with concentration values reported by NBS for the primary standard cylinder; 2. Uncertainties associated with the RTI injection of the primary NBS calibration cylinder, and the error associated with peak area meas- urement; 3. Uncertainties associated with the RTI injection of the sample cyl- inder and the error associated with the peak area measurement. The analytical results are reported as the mean parts-per-billion value for three replicate injections of a given sample cylinder plus or minus the calculated total uncertainty in parts-per-billion. The total uncertainty at the 95% confidence limits is calculated as follows: u (95% confidence) = x * 2 (a/2)2 + b2 + C2) where: x = Mean concentration in ppb; a = Uncertainty (95% confidence) associated with the concentra- tion value of a given organic, reported by NBS for the NBS- traeable standard mixture, expressed as relative standard deviation; b = Uncertainty associated with the RTI analysis imprecision (one standard deviation) of the NBS-traceable standard used for calibration, expressed as relative standard deviation. c = Uncertainty associated with the RTI analysis imprecision (peak area, one standard deviation) of the sample cylinder, expressed as relative standard deviation. 93 ------- In this manner, the total uncertainty at the 95% confidence limit is assigned to the concentration of each organic determined in the audit cylin- der mixtures. The question of whether the uncertainties expressed in the above equa- tion should be pooled in quadrature or linearly to obtain the total uncer- tainty is currently under statistical evaluation by NBS/EPA/RTI. Any modification to this equation, including the consideration of the number of analyses involved in the b and c terms, will be addressed in the future report. 94 ------- SECTION 5 SUMMARY AND CONCLUSIONS Cylinder gases containing 29 gaseous organic compounds at parts-per- billion levels have been used successfully in audits to assess the relative accuracy of analytical systems, especially those used during hazardous waste trial burn tests and ambient air monitoring. The cylinder gases contain five mixtures of five, six, eight, nine and eighteen organic compounds each. These mixtures were blended by a commercial specialty gas supplier in alumi- num cylinders in a balance gas of nitrogen. The five component mixture (Group I) contains carbon tetrachloride, chloroform, tetrachloroethylene (perchloroethylene), vinyl chloride and benzene. The nine component mixture (Group II) includes trichloroethylene, 1,2-dichloroethane, 1,2-dibromo- ethane, acetonitrile, trichlorofluoromethane (F-ll), dichlorodifluoromethane (F-12), bromomethane, methyl ethyl ketone and 1,1,1-trichloroethane. The eight component mixture (Group III) includes pyridine*, vinylidene chloride, 1,1,2-trichloro 1,2,2-trifluoroethane (F-113), 1,2- dichloro 1,1,2,2-tetra- fluoroethane (F-114), acetone, 1,4-dioxane, toluene, and chlorobenzene. The six component mixture (Group IV) includes acrylonitrile, '1,3-butadiene, ethylene oxide, methylene chloride, propylene oxide, and o-xylene. The eighteen component mixture (Group V) includes vinyl chloride, chloroform, carbon tetrachloride, methylene chloride, 1,2-dichloroethane, trichloroeth- ylene, benzene, tetrachloroethylene, 1,3-butadiene, bromomethane, trichloro- fluoromethane (F-ll), 1,1,1-trichloroethane, 1,2-dichloropropane, 1,2-dibro- moethane, toluene, chlorobenzene, ethylbenzene and o-xylene. Stability studies for 29 compounds (Group I, Group II, Group III, Group IV and Group V) have been performed to determine the feasibility of using them as audit materials. Results indicate that all of the organics tested (with the exception of ethylene oxide and propylene oxide) are stable enough to be used as reliable audit materials. Subsequent to completion of the stability studies, 198 performance audits have been initiated to date with Group I, Group II and Group III cylinders and 172 are complete. Generally, the audit results are within +_ 50 percent of the audit concentrations measured by RTI. *Although Group III cylinders contain pyridine, it is not included in the cylinder gases due to severe analytical difficulties. 95 ------- REFERENCES 1.

Using the clamps supplied, secure the manifold and rotameter vertically to the stand. The larger end of the manifold should be temporarily up, so the thermometer can be inserted. 2. Connect the heating controller to the tape and adjust the dial to heat the manifold to approximately 1008C. On assemblies with 1" tape (closely wrapped), a setting of 5 is sufficient to attain 100°C. On assemblies with 1/2" tape (loosely wrapped), a setting of 7-1/2 is required. 3. After the manifold temperature has become stable, remove the thermometer, invert the manifold (larger end down) and attach the shorter 3/8" 00 tubing by sliding the end sleeve-wise over the glass. 4. Attach the 1/8" tubing (union end) to the teflon nut on the top of the manifold. The 3/8" Swagelock"1 nut-end connects to the regulator at the reduced-end fitting. 5. Consult diagram for attaching rotameter, longer exhaust tubing, and audit cylinder. 6. Adjust the regulator to start the gas flow. The audit kit-supplied rotameter is downstream of the manifold and is used to monitor excess gas flow. 7. The rotameter will present negligible back pressure to the manifold. AP for 5 L/min is 1 inch of water column. 8. After sampling is completed, allow the manifold to cool, disassemble and repackage the audit kit into the case. Remember to include the teflon nut on the end of the manifold. The tubing can lie flat on top of the repackaged kit, loosely coiled. 9. Ship the case inside the box it came in, by United Parcel Service (UPS) B-4 ------- INSTRUCTION SET NO. 1 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 precision of the principal 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 organization prior to the actual trial burn tests. 2.0 PRINCIPLE A gas sample containing POHC 1s 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 collection 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 cylinder. 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. Determine 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. 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. ------- INSTRUCTION SET NO. 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 precision 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 chromatography/ 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 connected 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 manifold 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 CYLINDER) 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 supplied 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 use. 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 system. 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 collection is accomplished by opening the valve at the inlet to the first condenser, turning on the pump and sampling at a rate of 0.5 L/min for 20 minutes or IL/min for lOmin. The sampling rate is measured with the rotameter which 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 tow more times with two new pan's 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. ------- 1/8 to 1/4" Union 1/8" Teflon Audit Tank 00 I Cylinder Strap Glass Manifold & Heat Tape Long 3/8" Tube Output from Variable Excess to Hood 3/8" Swagelok Rotometer 3/8" Swagelok Variable Transformer Mounted in Case : 110 VAC Line Cord Travel Case Figure 1.
