Column chromatography silica gel is white powder, processed by special silica gel, the main component is silica, and the chemical properties of the product are stable. In the air can absorb moisture, because of the difference in the adsorption and retention time of different substances, can make various substances to achieve the purpose of separation and purification. It has short separation time, high sensitivity, clarity and no diffusion.

Silica gel column chromatography is mainly used for the removal of aromatic hydrocarbons from petroleum products, organic gas, liquid selectivity
