Thin layer Chromatography Silica Gel

Product Description:
Characteristics:
Thin-layer chromatography silica gel is a white, high purity, powder reagent silica gel, its chemical composition is SiO2. It is a strong polar solid adsorbent of hydrogen bonds type, non-toxic, tasteless, insoluble in water and organic solvents. It does not react with any other chemical materials except for hydrofluoric acid and hot alkali. Thin-layer chromatography silica gel is a kind of porous material with specific distribution of pore size, surface hydroxyl, and size. Due to the different adsorption and desorption time of the different components in mixed system in its hole, separation or purification achieved.
Think-layer chromatography silica gel is mainly used for coating thin layer chromatography silica gel plate, also can be used in qualitative or quantitative analysis of many types of organic substances. Thin layer chromatography silica gel H can be directly used as a dry cleaner carrier. Thin layer chromatography silica gel have been widely applied in teaching, clinical, research, production in pharmaceutical industry, plant chemistry, food chemistry, bio-engineering, clinical chemistry, chemistry and chemical engineering, material chemistry, law review analysis, environmental chemistry, life science.
