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.
column chromatography silica gel use diesel refinery, deodorization, waste engine oil recycling, bio-diesel and other mineral oil refinery.
