Column chromatography silica gel is white powder, processed by special silica gel, mainly composed of silica, stable chemical properties of the product. In the air can absorb moisture, because of its difference in the retention time of different substances adsorption, can make all kinds of substances to achieve the purpose of separation and purification. It has the advantages of short separation time, high sensitivity, clarity and non - diffusion.
Column chromatography silica gel is mainly used for 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 preparation of high purity substances.
