An evaluation of 27 gaseous organic compounds at parts-per-billion (ppb) levels in compressed gas cylinders has been conducted by the U.S. Environmental Protection Agency (EPA). 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 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 gas mixtures with time; and (4) to develop new audit materials as requested by EPA. The cylinders consist of 4 mixtures of 5, 6, 7 and 9 organic compounds each. These mixtures were blended by a commercial gas supplier in aluminum cylinders in a balance gas of nitrogen. To date, 95 performance audits have been initiated and 76 are complete. The results of these audits and description of the experimental procedures used for analyses and available stability data are presented in this Status Report No.3.
