摘要：An automated system wherein, under computer control, traces of organicchemical compounds in aqueous solutions are separated into a plurality of families ofcompounds. Several of the families are separated as separate extracts, dissolved inorganic solvents. The volume of solvent, containing each extract, is greatly reduced in aseparate pre-GC unit, to increase the ratio of extract to solvent volume. The output ofeach pre-GC unit is supplied to a separate gas chromatograph (GC). The elution times ofthe peaks, exiting the various GC's, are used in the selection of peaks of interest by thecomputer based on the comparison of the extract types and the elution times withelution times of known compounds. Peaks of interest from any of the several GC's aresupplied one at a time to an absorption cell of a single IR spectrometer through a peakstorage unit, which is designed to hold each peak of interest in one of its holding columnsuntil the spectrometer is ready to receive the peak. Compounds are identified by thecomputer based on their extract types, elution times and the spectral data from thespectrometer.
