Use of a Surface Acoustic Wave Detector Incorporated into a Field Portable Rapid Gas Chromatograph to Detect Chlorinated Hydrocarbons from DNAPL Contaminated Ground Water

摘要

A field portable GC fitted with a non-analyte specific surface acoustic wave detector (SAW) was used to monitor DNAPL plume migration at Lawrenece Livermore Laboratories, Berkeley. CA. The instrument is capable of producing complex chromatograms in 10-60s which were used to measure both qualitatively and quantitatively the extent of contamination by using reference standards of known concentration.
