Silica Gel for Column-layer Chromatography
* Characteristics
Column chromatographic silica gel is white and uniform granules, using high quality silica gel as raw material, the main component is silicon dioxide. It's main characteristic is that it can achieve the purpose of separation and purification by the difference of adsorbing retention time of different components in mixture.
* Application: as filter media.
1. Column-layer chromatography silica gel is used for separation and purification of active ingredients of Chinese herbal medicine and preparation of high-purity substances.
2. Refining petroleum products and selective adsorption and separation of organic gases and liquids.
