Column Chromatography Silica gel (silica gel,column chromatography silica gel,silica gel for column chromatography)

This product is made from premium quality silica gel

Its main characteristic is this product can realize separation and purification by the difference in adsorption and retaining time for different ingedients in compound


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



Use:
Separation and refinement of traditional Chinese herbal medicine components
Preparation of high purity substance
Refinement of petrol products
Removal of aromatic hydrocarbon material, etc
The prominent advantages of column chromatography silica gel in its application in biology engineering technology:
Sanpont products are made from premium quality silica gel with transparency, The silica gel have excellent adsorption performance; It has ideal separation function to similar character and structure, even to isomer
In the production, the time of acid treatment and aging are strictly controlled, also we adopt high-fired technique, so our silica gel have rigid skeleton structure, high mechanical strength,can stand the pressure within 30MPa
it has good thermal stability and chemical stability, can have selective adsorption and purification of the components of isomer from multi-component solution.
in preparation of column chromatography silica gel, a series of products with average pore diameter 20A-20000A can be produced through the control of different process conditions in order to adapt to the separation and purification of the substances with different character, molecular weight and molecular structure
Sanpont silica gel purity is above 99 ,compared with organic column padding, silica gel is a solid, colloidal gel based on SiO2 matrix,its structure is compact, so even be directly thrown away, the silica gel will not pollute environment
