EPA has initiated a national QA program on the suppliers of Protocol Gases. In the program, which will operate continuously, Protocol Gases are obtained and analyzed by EPA. The results of the EPA analysis are then compared to the Certificate of Analysis supplied with the Protocol Gas. Reported here is a comparison between the assay results obtained by EPA on Protocol Gases for SO2 and NO and the concentrations provided by the suppliers of the Protocol Gases. The results are being released on the Technology Transfer Network operated by the Office of Air Quality Planning and Standards of the EPA, Durham, N.C.
