Product brief introduction
Product Introduction
TLC silica powder is white, and efficient two general points. The main ingredients of SiO2 • nH2O, do not dissolve in water, inorganic acids and other organic solvents, dissolved in concentrated hydrofluoric acid and caustic solution. In the air to moisture absorption. Because of adsorption of different substances on the retention time differences, the various substances to enable separation and purification purposes. There H, HF254-G type of ion. H-free gypsum and organic binder; HF254-containing inorganic phosphors, in a 254nm wavelength UV yellow-green fluorescence; G-containing around 13% gypsum as adhesives, slightly acidic; Ion - water-containing gypsum and inorganic phosphors, in the ultraviolet wavelength 254 nm showed yellow-green fluorescence.
Bug directly for various types of organic material and the qualitative or quantitative analysis, in medicine, pesticides, Chinese herbal medicine and organic chemical products and food, food of trace impurities and the identification of major components have been widely used. One more efficient TLC silica particles absorbed, small features, and compared to ordinary silica gel thin-layer chromatography, the separation of material better.
Packaging products bearing the head with a white polyethylene plastic bottle packaging, weighing 500g bottle, overpack with cartons each containing 10 bottles. Or, as required by other packaging.
