Column layer chromatography si

Properties: this product is white uniform particles, the main composition is sio2, made from high quality silica gel as the raw material processing. Its main characteristic is to through the different components of mixed material adsorption retention time differences, achieve the purpose of separation and purification. According to its purity is divided into industrial-grade coarse bore log chromatography silica gel column chromatography silica gel, reagent level.

Purpose: column layer chromatography silica gel is mainly used for refined petroleum products, removing aromatic substances or used for separation and purification of effective components of Chinese herbal medicine, the preparation of high purity material, etc.

Specifications:
