Just a short silica gel plate, its full name should be called TLC silica gel plate, which uses high-purity thin layer chromatography on silica gel (powder) transferred into a certain amount of spray adhesive, it is generally a glass plate surface, this year come, the more popular abroad do use aluminum foil attached to the board.
Silica gel plate is a highly active adsorption material is amorphous material, its chemical formula is mSiO2 · nH2O. Insoluble in water and any solvent, non-toxic, odorless, chemically stable, does not react with any substance except alkali, hydrofluoric acid. Various types of silica is formed due to different manufacturing methods of different pore structure. Chemical composition and physical structure of silica gel, and determines that it has many other similar material was difficult to replace characteristics: high adsorption properties, good thermal stability, chemical stability, high mechanical strength.
Silicone based on its pore size is divided into: large pore silica, silica rough hole, B-type silica gel, silica pores.
Can be directly used for many types of rapid separation of organic substances - the qualitative or quantitative analysis. In the identification of pharmaceuticals, pesticides, herbs, organic chemical products and food, food trace impurities and main ingredient has been widely used.
