intro:
1.Description and uses
This prodrct is refined specially with excellent silica gel of high purity, the main component is SiO2nH2O which is waterfast, indiscerptible in inorganic-acid and other organic solvents, it can be solved in HF and caustic lye, and since the time it adsorbs and reserves on different substances are different, it can separate and purify different substances. This can be used directly on the nature-determination and ration analysis of all kinds of organic substances, and is widely used on the analysis of microimpurity and main components of medicine, herbal medicine, foodstuff and so on. It has styles of H, HF254, G, GF254.
