【introduction】
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.
【 characteristics 】
High pressure, high efficiency, high speed, high sensitivity and high selectivity.
【 structure composition 】
Liquid reservoir, pump, sample injector, chromatographic column, detector and recorder.
【 application 】
Gasoline, lubricating oil, polyaromatic hydrocarbon, saturated hydrocarbon, heavy hydrocarbon, crude oil composition analysis, colloid analysis, asphalt analysis, etc. Food additives, food pollutants, preservatives, colorants, sweeteners, oxidants, food drug residues; Separation, purification, analysis and synthesis of drugs.
