Preparation of high purity substance.
Refinement of petrol products..
Removal of aromatic hydrocarbon material, etc. Characteristies
The gel performed as white grains of homogeneous size. Chief ingredient is silicon dioxide. Of high purity. Secure and sanitary.
Column chromatography silica gel belongs to colloidal-state system with solid characteristics, which is composed of colloidal particles with condensate structure. The colloidal particle is the polycondensate of hydrated silica gel (multi-silica acid), belongs to a non-crystalline-state substance. The interspace of aggregation of colloidal particle forms the inner micro interspace structure of reagent 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.
the performance of column chromatography silica geladsorption, which depends on the fine porous structure and the surface of inner pore formed in process of the raw material silica gel production.
