||A gas chromatographic method for volatile organic chemicals in which an aqueous sample is purged directly to a cryogenically cooled, fused silica column uses a Nafion tube drier between the purge vessel and GC column. The Nafion strips water from the gas stream during the purge step while allowing volatile halocarbons and aromatics to continue to the GC column. Examples of the technique are presented on 0.53 mm and 0.25 mm fused silica columns coated with a variety of stationary phases. (Copyright (c) 1988 Dr. Alfred Huethig Publishers.)
