A systematic approach to pesticide identification developed by Suzuki uses column chromatography, thin-layer chromatography and gas-liquid chromatography. Mass spectroscopy (MS) is also a powerful tool for the identification of compounds. ... The Environmental Protection Agency (EPA) had defined volatile priority pollutants as those amenable to analysis by the purge-and-trap method of sample preparation. ...

The EPA method of screening for volatile compounds involves purging the sample with helium and trapping the volatilized organic compounds on a column of Tenax GC and silica gel at room temperature. The organic material is then thermally desorbed onto the gas chromatographic column....
