Column Chromatography Silica Gel:
        This product is white grain of homogeneous size and made from premium quality silica gel with fine workmanship. Due to the duration time difference of absorption to different ingredients in compound Characteristic, it can achieve the purpose of separation and purification of mixed composition.            
       The interspace of aggregation of colloidal particle forms the inner micro interspace structure of column chromatography silica gel particle. Therefore, it is a kind of premium quality adsorption material with rich fine porous structure, high specific surface area, high purity and high activity.  It's used in separation, purification of chemistry of Pharmaceutical Synthesis, Organic Synthesis, chemistry of natural product and Natural Pharmaceutical Chemistry, etc.
