Binary Pumps Hplc System Liquid Chromatography Instrument In Analytical Chemistry
Binary Pumps hplc System High Performance Liquid Chromatography Instrument in Analytical Chemistr
Introduction of Liquid Chromatography Instrument
The high performance liquid chromatography instrument is mainly used for the analysis of organic compounds with high boiling point, non-volatile, heat unstable and large molecular weight. It consists of a reservoir, pump, injector, column, detector, recorder and several other parts. There are binary high pressure and quaternary low pressure modes availiable. The column oven is equipped with a refrigeration function as standard, extending the application range of the system. A variety of detectors are available, such as UV, DAD, ELSD, FLD, etc.
