LC3200 HPLC Liquid chromatography High Performance Liquid Chromatograph

Product Description

High performance liquid chromatograph (HPLC) is an instrument based on the principle of high performance liquid chromatography, which is mainly used to analyze less-volatile and thermal-unstable organic compounds with high boiling point and large molecular weight. It consists of reservoir, pump, sample injector, chromatographic column, detector and recorder.
