ANALYSIS OF HAZARDOUS WASTE AND ENVIRONMENTAL EXTRACTS BY CAPILLARY GAS CHROMATOGRAPHY/FOURIER TRANSFORM INFRARED SPECTROMETRY AND CAPILLARY GAS CHROMATOGRAPHY/MASS SPECTROMETRY.

Description:
The relative sensitivities of fused-silica capillary column gas chromatography/Fourier transform infrared spectrometry (FSCC/GC/FT-IR) versus packed-column GC/FT-IR and FSCC/GC/FT-IR versus fused-silica capillary column gas chromatography/mass spectrometry (FSCC/GC/MS) were compared. As part of this study, complex environmental extracts were analyzed by both FSCC/GC/FT-IR and FSCC/GC/MS. The on-line library search results for both techniques were compared with the visually-checked spectral results for all FSCC/GC/FT-IR detectable analytes. Positive analyte identification depended strongly on sample preparation technique, search library content, chromatographic resolution and compound class. It was concluded that a target compound approach would not have utilized much of the available analyte information in these extracts.
