Operation and Principle of Liquid Chromatograph


Liquid chromatography is divided into liquid-liquid chromatography (LLC) and liquid-solid chromatography (LSC) according to whether the stationary phase is liquid or solid. Modern liquid chromatograph consists of high-pressure infusion pump, injection system, temperature control system, chromatographic column, detector, signal recording system and so on. Compared with the classical liquid column chromatography device, it has the characteristics of high xiao, fast and sensitive.
