HPLC Liquid Chromatography Instrument with Quartnary Pump UV Detector
Introduction of Liquid Chromatography Instrument
The high performance liquid chromatography instrument with the characteristics of high operation stability, high detection sensitivity and modular designing. It is mainly used to analyze less-volatile and thermal-unstable organic compounds with high boiling point and large molecular weight in ther area of pharmaceutical, chemical, environmental, food, laboratories and other fields . It consists of reservoir, pump, sample injector, chromatographic column, detector and recorder.
