Column chromatography silica gel is white powder, processed by special silica gel, the main component is silica, the chemical properties of the product is stable. In the air can absorb moisture, because of the difference in the adsorption retention time of different substances, can make a variety of substances to achieve the purpose of separation and purification. Its short separation time, high sensitivity, clear, non - diffusion.

Column chromatography silica gel is mainly used for the selective adsorption and separation of aromatic substances, organic gases and liquids from petroleum products. Used as catalyst carrier, chromatographic support; It can also be used for the preparation of high purity substances.
