1.Description and uses
Silica Gel for Column-layer Chromatography is refined with excellent silica gel. Its main component is SiO2nH2O, which is waterfast, indiscerptible in inorganic-acid and other organic solvents, it can be solved in HF and caustic lye, it can absorb moisture from air, and since the time it adsorbs and reserves on different substances are different, it can separate and purify different substances. This product is mainly used to refine petrol products and to eliminate aryl-aldehyde substances, and used on the selective adsorption and separation of organic liquid and gas, and on the separation, purification of effective components of herbal medicine, the preparation of high-purity substance and used as carrier of activator and chromatogram picul.
