42MPa Isocratic High Pressure HPLC Liquid Chromatography System in Pharmaceutical Industry
Description of HPLC Liquid Chromatography Instrument
High-performance liquid chromatography (HPLC) is a technique in analytical chemistry used to separate the components in a mixture, and to identify and quantify each component. It was initially discovered as an analytical technique in the early twentieth century and was first used to separate colored compounds.
