The column chromatography silica gel produced by our company is made of high-quality silica gel as raw material. The purpose of separation and purification is achieved through the difference of adsorption retention time of different components in the mixture. Silica gel for column chromatography is white uniform particles, the main component is silica, the purity is very high, and safety and health. In addition, it is also a colloidal system with solid properties, which is composed of colloidal particles with agglutination structure. Colloidal particles are polycondensates of silica gel (polysilicic acid) in hydrated state and belong to amorphous state. The gap of the aggregation of colloidal particles forms the micropore structure inside the silica gel particles. Therefore, column chromatography silica gel is a kind of high-quality adsorption material with rich microporous structure, high specific surface area, high purity and high activity. Column chromatography silica gel has outstanding advantages in the application of bioengineering technology: first, our company's products are made of high-quality silica gel with high transparency, excellent adsorption performance, and ideal separation function for properties, structure similarity and even isomers. Second, in the process of raw material production, our company strictly controls the acid bubble and aging time, and adopts high-temperature calcination technology. Therefore, Jiangyou column chromatography silica gel has a rigid skeleton structure, high mechanical strength, and can withstand the pressure within 30MPa. Third, Jiangyou silica gel has good thermal stability and chemical stability. It can selectively adsorb and purify isomeric components from multi-component solution. Fourth: in the process of preparing silica gel for column chromatography, our company also produces a series of products with an average pore diameter of 20-20000? By controlling different process conditions to adapt to the separation and purification of substances with different properties, molecular weight and molecular structure. Finally, the purity of silica gel in Jiangyou column chromatography is more than 99%. Compared with the organic column packing, silica gel is a solid colloid with SiO2 as the matrix, and its structure is compact, even if the organic matter loss occurs and pollutes the target product directly.
