Column chromatography silica gel properties and advantages

The column chromatography silica gel is made of high quality silica gel as raw material. The column chromatography silica gel is white uniform particles, and the main component is silica. Its main feature is that it can achieve the purpose of separation and purification by adsorbing the difference of retention time of different components in the mixture. It has the characteristics of high purity, safety and hygiene.

Column chromatography silica gel is a colloidal system having solid characteristics and consists of colloidal particles forming an agglomerated structure. The colloidal particles are polycondensates of hydrated silica gel and are amorphous. The gap between the aggregates of the colloidal particles forms a microporous structure inside the reagent column chromatography silica gel particles. Therefore, it is a high-quality adsorption material with rich microporous structure, high specific surface area, high purity and high activity.

Reagent column chromatography The main performance characteristics of silica gel are adsorption characteristics, depending on the microporous structure and the surface of the pores formed during the production of silica gel. Column chromatography silica gel is used for separation and purification of active ingredients of Chinese herbal medicine, preparation of high-purity materials, dehydration of petroleum products, dehydration and purification of column chromatography. In the process of raw material production, the acid bubble and aging time are strictly controlled, and high temperature is adopted. Calcination technology, so silica gel powder has a rigid skeleton structure and high mechanical strength.

Column chromatography silica gel has good thermal stability and chemical stability, and selectively adsorbs and purifies the isomer components from a multi-component solution. In the preparation of column chromatography silica gel, a series of products with different pore sizes can be produced by controlling different process conditions to adapt to the separation and purification of substances with different properties, molecular weights and molecular structures. The purity of the column chromatography silica gel is as high as 99%. Compared with the organic column packing, the silica gel is a solid SiO2 matrix colloid and has a compact structure.
