Column chromatography silica gel 200-400 mesh silica powder

Column chromatography silica gel is processed and manufactured using coarse-pore silica gel as the raw material. Its main characteristic is the ability to achieve separation and purification by leveraging the differences in adsorption retention times of various components in a mixture.It is a commonly used separation and purification technique, widely applied in fields such as chemistry and biology.

Principle of column chromatography silica gel: The separation principle of silica gel chromatography is based on the varying adsorption forces of substances on silica gel. Substances with higher polarity interact strongly with silica gel, resulting in longer retention times, while substances with weaker polarity interact weakly, leading to shorter retention times. Through repeated adsorption and desorption processes between the stationary and mobile phases, substances are separated.

Packaging: The product is packaged in composite bags, 20 kg per bag, or other packaging methods as required.

Storage: Store in a dry, well-ventilated area, and avoid storing together with volatile substances.
