Superiority:

Qingdao hailihe column chromatography silica gel raw material silica gel is specially customized according to the structural characteristics of column chromatography silica gel, with specific pore structure, pore size distribution and surface hydroxyl distribution, at the same time has the characteristics of high purity, low impurity content, low trace impurity dissolution, pollution-free to the separated substances.In the process of production, the patented vibrating screen conforming to the principle of human bionics is used, and the product size separated from the screen is evenly distributed. The theoretical tray number is high, the column efficiency is high, the peak capacity is large, and the resolution is high.When used, the flow rate of both atmospheric and pressurized columns is stable.

Details:

Column layer chromatography silica gel for porous material, the surface was covered with silicon hydroxyl, due to the different components in the mixed system was active site in its hole - silicon hydroxyl adsorption, and on the active site - silicon hydroxyl, the solvent and solute molecules in the mixture system, competitive adsorption between the solute molecules and, thus caused the difference of different residence time in the column, so as to achieve the purpose of separation and purification.
