Silica Gel for Colunm Chromatography，400-800 Mesh

Column chromatography silica gel is made of high quality silica gel processing, the main component is silica. Column chromatography silica gel is a kind of high quality selective adsorption material with high specific surface, high purity and high activity. The column chromatography silica gel can achieve the separation and purification of different mixed components because of its different adsorption and retention time. It is mainly used for the separation and purification of the active ingredients of Chinese herbal medicine, refining of petroleum products, chromatographic support or support raw materials, and removal of aromatic substances.
