Abstract A repository of 42 gaseous compounds including hydrocarbons, halocarbon, and sulfur species has been established under contract with the U.S. Environment Protection Agency (USEPA). The main objectives of this on-going project are (1) to provide gas mixtures to EPA, state/local agencies, or their contractors, as performance audits to assess the accuracy of source emission measurements in certain organic chemical manufacturing inductries, (2) to corroborate the vendor's certified analysis of the gas mixtures by in-house analysis, (3) to determine the stability of the gas mixtures with time by in-house analysis, and (4) to explore the feasibility of new audit materials as requested by EPA. Thus far, 28 compounds have been used to conduct 106 different audits. The results of these audits and a description of the experimental procedures used for analyses and available stability data are presented in the status report. Seventy percent of the audit results are within 10 percent of the expected values. Compound stabilities have been determined through multiple analyses of the cylinders containing them. Stability values for all compounds are expressed as percent change per month. Calculated changes are typically found to be a few tenths of one percent per month, though many of these changes may not be significantly different from zero.
