GC systems

GC systems are gas chromatographs used to separate and measure the volatile and semi-volatile compounds in a sample by carrying it in a gas stream through a column that retains each component for a different length of time. They cover the complete instrument, the injector, the oven-held column, the detector, and in many cases an autosampler and data system. On Questpair, 414 GC systems are listed, and 99 percent of the listings are used. Prices run from EUR 40 to EUR 64.567. New, used and refurbished laboratory units all appear, so a buyer can compare a bare benchtop chromatograph against a full configuration with mass spectrometric detection inside one catalogue.
