HPLC systems

HPLC systems are instruments that separate the components of a liquid mixture by pumping it under high pressure through a packed column, so each compound can be identified and quantified. A complete system pairs a pump, an injector or autosampler, a column compartment and one or more detectors into a single liquid chromatography workflow. Of the current listings, 99 percent are used, drawn from 17 verified suppliers and distributors across 12 countries. New, used and refurbished units all appear in the Questpair catalogue, with laboratory prices spanning a wide band. This class of instrument underpins routine analysis in pharmaceutical, environmental and food testing laboratories.
