【Character】

Thin layer column chromatography is white powder and main content is silicon dioxide. It’s insoluble in water and organic solvents. Because of the difference in retention time of different substances, it can make various substances achieve the purpose of separation and purification.

【Application】

It is used for refinement of petroleum products (removal of aromatic hydrocarbons and other organic compounds), selective adsorption and separation of liquids, preparation of catalysts and chromatographic carriers. It is also a simple, fast and sensitive analytical reagent for column analysis of medicine, pesticides, dyes and rubber.
