Abstract

A capillary gas chromatography/Fourier transform infrared (GC/FT-IR) spectrometer has been linked to a Mass Selective Detector (MSD). A 10:1 effluent splitter was used to divert 90% of the GC effluent to the FT-IR cell and 10% tO the MSD. This system has been used to characterize the GC-volatile portion of dye and herbicide manufacturing wastes, sediments, sludge extracts, and the extract of a freshwater turtle. Use of a 2300 member FT-IR spectral data base, in conjunction with the NBS mass spectral (MS) data base, greatly increases the number of on-line MS confirmations obtainable by this direct-linked system over that of the conventional EPA GC retention time method. Chromatographic separation on a single capillary GC column allows a direct one-to-one correlation of peaks in the FT-IR and MSD chromatograms. Although this MS detector is 10 to 100 times more sensitive than the FT-IR detector used, and although the MS search library is over 15 times larger than the FT-IR search library, for the samples analyzed it was determined that each detector provided approximately the same amount of useful structural data.
