A modular field deployable gas chromatograph/ion trap detector system for characterization of hazardous waste sites was described. The second generation transportable gas chromatograph/ion trap detector (GC/ITD) was extensively based on commercial instrumentation. A purge and trap gas chromatograph was used for sampling and separating volatile organic compounds from the environmental matrix before their introduction to the ion trap detector for mass spectral analysis. The ion trap detector provided many advantages as a mass analyzer in this application. The high sensitivity of the ion trap and the inherent universality of the modular mass spectrometer system were important features for field analysis. The instrument provided high specificity for compound identification due to the two dimensional information provided by chromatographic retention time and mass spectral library identification.
