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.
