high purity silica sand

White grains of homogeneous size.Chief ingredient is silicon dioxide.Of high purity.Secure and Sanitary.

General Description:

     White grains of homogeneous size.Chief ingredient is silicon dioxide.Of high purity.Secure and Sanitary.Can be used to separate and refine mixed components because different components have different absorption duration on this silica gel.

     Silica gel column chromatography is made from high silica gel processing and become, the main composition is silicon dioxide. Silica gel column chromatography is one with high surface, high purity, the high quality highly selective adsorption materials. Silica gel column chromatography because of their different material components for different time adsorption, can make a mixture of different components to achieve the purpose of purification. Mainly used for Chinese herbal medicine effective ingredients of purification, refined petroleum products, chromatographic bear the body or bear the body materials, aromatic material removal, etc.

Use:

For refinement of petrol products, removal of aromatic hydrocarbon material, separation and refinement of traditional Chinese herbal medicine components, preparation of high purity substance,etc.
