HPLC, Liquid Chromatography

High-performance liquid chromatography (HPLC) is an analytical technique that separates, identifies, and quantifies compounds dissolved in a liquid by forcing the sample through a packed column under high pressure. An HPLC system combines a pump, an injector or autosampler, a separation column, and a detector into one instrument, and the method underpins routine work in pharmaceutical quality control, environmental testing, and food analysis.
