Intelligent High Performance Full-controlled hplc Liquid Chromatography Instrument
Introduction of HPLC Liquid Chromatography Instrument
High performance liquid chromatograph (HPLC) is consists of reservoir, pump, sample injector, chromatographic column, detector and recorder. And it is mainly used to analyze less-volatile and thermal-unstable organic compounds with high boiling point and large molecular weight.
