| Abstract |
An evaluation of 29 gaseous organic compounds at PPB levels in compressed gas cylinders was conducted by the U.S. Environmental Protection Agency (EPA). Primary objectives of this on-going project are to: (1) evaluate the quality of measurements made by EPA, state/local agencies or their contractors by using ppb gas cylinders for performance audits to assess relative accuracy of source measurement systems during hazardous waste trial burn tests and ambient air monitoring programs; (2) verify the manufacturer's certified analysis of the multi-component gas mixtures; (3) determine stability of gas mixtures with time; and (4) develop new audit materials as requested by EPA. Cylinders consist of 5 mixtures of 5, 6, 7, 9, and 18 organic compounds each. These mixtures were blended by a commercial gas supplier in aluminum cylinders in a balance gas of nitrogen. To date, 198 performance audits have been initiated and 172 completed. Results of these audits and description of experimental procedures used for analyses and available stability data are in Status Report No. 4. |
