Qingdao Chenrong Column Chromatography Silica Gel 300-400 Mesh for Biomedical Separation and Purification

I. Introduction to Column Chromatography Silica Gel: Column chromatography silica gel, also known as chromatographic media, is a high-purity white powder processed from silica raw materials with a specific particle size distribution range. It is widely used in pharmaceuticals, chemicals, botanical extraction, biochemistry, and other industries.

II. Principle of Column Chromatography Silica Gel: The separation principle of silica gel chromatography is based on the differential adsorption of substances on silica gel. Highly polar substances interact strongly with silica gel, resulting in longer retention times, while weakly polar substances interact weakly, leading to shorter retention times. Through repeated adsorption and desorption processes between the stationary and mobile phases, substances are separated.
