hplc columns
the system of liquid chromatographic column is composed of liquid reservoir, pump, injector, column, detector, recorder and other parts. The mobile phase in the liquid reservoir is pumped into the system with a high-pressure pump. The sample solution is injected into the mobile phase with the injector, and is carried to the column (stationary phase) by the mobile phase. As different components of the sample solution have different partition coefficient in two phases, when the sample is moving relatively in the two phases, through repeated times of adsorption-desorption partition, each component has much difference on moving rates. So they are separated into individual component and effluents from the column in series. When the components pass the detector, the respective concentrations are translated into electronic signal to the recorder. Finally, the data are printed as spectrum.
hypersil packing
hypersil packing is a kind of hplc packing with silica gel matrix, which has granularity of 3μm, 5μm and 10μm, aperture of 120å. The standards of quality control while producing are very strict. Hypersil packing has an application of more than 20 years. The application examples of hypersil packing are mentioned in many literatures and famous magazines.
