| Abstract |
EPA currently regulates or plans to regulate over 130 organic and 20 inorganic gases as air pollutants. These compounds can be found in air matrices from 1 ppb to 1000 ppm and in different relative ratios. The presentation describes the evaluation of a gas transfer system that will allow an organization to prepare a wide variety of QA and QC audit gas mixtures using a small number of master gas mixtures. It has been used in the laboratory to prepare over 60 mixtures for use as performance evaluation and audit materials in support of the EPA regulations. |
