Transportable GC/ion trap mass spectrometry for trace field analysis of organic compounds.

摘要

A transportable purge and trap/GC/MS based on the Finnigan Ion Trap Detector (ITD) has been developed at Los Alamos National Laboratory for the identification and quantification of volatile organic compounds present at chemical waste sites. This instrumentation is being evaluated for use to support environmental surveillance and the characterization/clean-up of hazardous waste sites. A custom purge and trap/GC sampling system was integrated with a modified ITD to achieve instrument operation consistent with field activities. The sampling system is controlled by an ancillary microprocessor designed at Los Alamos National Laboratory. The instrument is extensively automated and can be operated with minimal training. Instrument operation transparent to the field user has been achieved by integrating sampling system control software with the operating software of the ITD. 3 refs., 7 figs.
