High performance liquid chromatography is a chromatographic separation methods, it is a liquid as mobile phase, using high pressure infusion system, will have different models of single solvent or different proportion of mixed solvent, buffer, such as mobile phase pump into a stationary phase chromatographic column, the injector valve injection sample under test, and brought into the column by the mobile phase, each component is separated in the column, in turn into the detector for testing, so as to realize the analysis of the sample.
