柱层析硅胶Column Chromatography Silica Gel

  柱层层析硅胶为白色粉末，主要成分为SiO2·nH2O，不溶于水、无机酸和其它有机溶剂，溶于氢氟酸和浓苛性碱溶液。在空气中能吸潮。因具有对不同物质吸附保留时间上的差异，能使各种物质达到分离提纯目的。  

Column chromatography silica gel is white powder, the main component is SiO2·nH2O, insoluble in water, inorganic acid and other organic solvents, soluble in HF and concentrated caustic soda solution. It absorbs moisture in the air. Because of the difference in adsorption and retention time of different substances, various substances can be separated and purified.
