GC, Gas Chromatography

Gas chromatography is an analytical technique that separates volatile and semi-volatile compounds in a sample by moving them through a column in a carrier gas stream, with each compound eluting at a characteristic time. A gas chromatograph is the instrument that performs this separation, pairing an injector and a temperature-controlled column oven with a detector that records what leaves the column. The Questpair catalogue lists 882 gas chromatography listings from 18 verified suppliers and distributors across 12 countries. New, used and refurbished units appear here, and 97 percent of the listings are used. Prices run from EUR 4 to EUR 107.611, so a benchtop laboratory system and a full detector-equipped platform sit in the same catalogue.
