EPA has identified over 130 organic and 20 inorganic gases that it is now regulating or plans to regulate as air pollutants. These compounds are covered by a variety of environmental regulations such as RCRA, NSPS, NAAQS, TSCA, NESHAPS, and CERCLA. These compounds can be found in the air from 1 ppb to the 1000 ppm range and in different relative ratios. A gas transfer system is described in this presentation that will allow an organization to prepare a wide variety of QC and QA materials for these gases using a small number of stock gases in compressed gas cylinders. The experiments conducted to characterize the performance of this system to date and the additional experiments planned are described.
