Performance and Application

Silica gel for column chromatography is white uniform particles with silicon dioxide as the main component. It features high purity, safety and hygiene.

This product is finely processed from high-quality silica gel. Due to the different adsorption and retention times for various components, it can separate and purify various substances. It is mainly used for refining petroleum products and removing aromatic hydrocarbons. It also has selective adsorption and separation properties for other organic gases and liquids.

It can be used as a catalyst carrier in chemical processes, and also as a chromatographic support for the separation and purification of effective ingredients in Chinese herbal medicines, as well as the preparation of high-purity substances. It is also a simple, rapid and sensitive analytical reagent for column analysis in medicine, pesticides, dyes, rubber and other fields.
