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。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.

本品主要用于石油产品精制脱除芳烃类物质，有机气体、液体的选择性吸附分离；用作催化剂载体，色谱担体；还可用于中草药有效成分的分离、提纯及高纯物质的制备。 

The product is mainly used for refining petroleum products to remove aromatic substances, organic gas, liquid selective adsorption separation; Used as catalyst carrier, chromatographic support; It can also be used for the separation and purification of the active ingredients of Chinese herbal medicine and the preparation of high purity substances.
