The full name of the silica gel plate is thin-layer chromatography silica gel plate, which is made of high-purity thin-layer chromatography silica gel mixed with a certain amount of binder and sprayed. Silica gel plates can be used directly for rapid separation of many types of organic substances - qualitative or quantitative. It has been widely used in the identification of trace impurities and main components of medicines, pesticides, Chinese herbal medicines, organic chemical products, grains, and foods.
According to its properties, silica gel can be divided into two categories: organic silica gel and inorganic silica gel. Inorganic silica gel is a highly active adsorption material, which is usually prepared by reacting sodium silicate and sulfuric acid, and undergoing a series of post-treatment processes such as aging and acid soaking. Silicones are used in a wide range of applications. It is not only used as a special material in aviation, cutting-edge technology, and military technology departments, but also in various sectors of the national economy. Its application range has expanded to: construction, electronics, textiles, automobiles, machinery, leather and paper, chemical industry Metals and paints, medicine and medical treatment, etc.
