Instruction:
Column chromatography silica gel is cellularity article; molecule contains interlinkage configuration of siloxane; meanwhile, the surface has lots of silanol base that has different keeping time for different content adsorption to achieve separation and purification.
Raw material of column chromatography silica gel contains definite configuration and contains low impurity according to requirement and characteristics of column chromatography silica gel. Testing standard: coarser mesh massive silica gel for lamina and column chromatography silica gel Q/02HHJ-Y-30-2001（2004）; it couldn’t be used until passed testing that guarantees stability of column chromatography. Meanwhile, it adopts gradable frequency conversion technology during manufacturing column chromatography that reduces existence of fine grain, guarantees equality of granularity, reduces column resistance and also guarantees average speed.
By right of special aperture configuration and stable quality, column chromatography silica gel wins huge praise from users.

Characteristics:
Column chromatography silica gel is white powder grain and the main content is silicon dioxide. It is innocuity, odorless and doesn’t dissolve in water and organic impregnant, which has high specific surface and definite aperture configuration. Meanwhile, it also has strong adsorption and is good for moisture adsorption.　

Application:
Column chromatography silica gel is applicable for fine of petroleum products, depredating arene or separation and purification of Chinese herbal medicine and preparation for high purity articles. Meanwhile, it can also be used as carrier of activator and eliminating impurity in waste oil.
