摘要：

A transportable gas chromatograph-ion trap detector has been developed for the in situ characterization of chemical waste sites. This instrument is based on a modular design and can be readily modified in the field for air, water, or soil sampling. A purge-and-trap gas chromatograph developed for this instrument is used for the separation of volatile organic compounds before their introduction to the ion trap for mass spectral analysis. A daughter microprocessor has been developed for the control of ancillary hardware via the ion trap software. Most analyses are accomplished in an automated 20 min procedure. The detection limit for trichloroethylene in water is in the low part-per-trillion range. The analysis of soil and water samples is demonstrated by using surrogate samples spiked with 24 volatile organic compounds. The instrument has been used under field conditions for soil analysis at a chemical waste site.
