A method for the automated analysis of volatile organic compounds in industrial effluents with a dedicated GC/MS (Gas Chromatograph/Mass Spectrometer) System has been developed for priority pollutant analyses according to EPA's Verification Protocol. The method allows confirmational analysis, in which specific priority pollutants, even at low levels and in the presence of interfering compounds, are determined with a mass spectral library reverse-search technique; and survey analysis, a forward library search technique that uses the EPA/U.S. National Institutes of Health/MSDC mass spectral data base. The method uses a Bellar-Lichtenberg type purge-and-trap device and a fully automated GC/MS analyzer. Most components can be determined at less than the l ppb level. Sample computer-generated plots are shown for chloroform, with a linear fit and a quadratic fit of peak area vs. amount of sample.
