Rushan Sun Desiccant Co., Ltd.

Column chromatography silica gel was used in the separation and purification of active components of Chinese herbal medicine, preparation of high purity materials, purification of petroleum products, dehydration and purification of organic substances, and the application of silica gel in biological engineering.

In the raw material production process, strictly control the acid soak and aging time, and take the high temperature calcination technology, so the column chromatography silica gel has a rigid skeleton structure, high mechanical strength, can withstand the pressure within 30MPa. Column chromatography silica gel has good thermal stability and chemical stability, and has a selective adsorption and purification of the isomers from multiple components. In the process of preparing column chromatography silica gel, a series of products with average diameter of 20A -20000A can be produced by controlling different technological conditions to meet the separation and purification of the material with different properties, molecular weight and molecular structure. The purity of silica gel column is more than 99%, compared with the organic column, silica gel is a solid with SiO2 as the matrix and the structure is compact, even if the organic matter is discarded directly, the target product is contaminated.
