2. Column chromatography silica gel

 Performance and usage: This product is prepared from fine silica gel. Complex components can be separated because the column chromatography silica gel has different adsorbing ability to different ingredients so as to the retention times of them on the column chromatography are different . It is mainly used to remove the aromatic hydrocarbon in the Petroleum products, and to separate the effective composition from Chinese herbal medicine .It is also used for preparation of high purity materials, beer, toothpaste, and cosmetics.
