Silica Gel Sorbent Technologies, Inc.

When considering Normal Phase chromatography techniques, plain silica gel is the optimal stationary phase due to it s high surface area (500-600 m² /g). Additionally, a 70 Å pore diameter works well for most analytes, especially those hav ing a molecular weight of less than 1,000 Daltons. Higher molecular weight analytes require larger pore diameters (>100 Å) for entrance into pores as well

Silica gel Chemical Product Catalog Chemsrc

2019-6-12 Silica gel, also known as silicic acid gel or silica gel, has the chemical formula mSiO2·nH2O, a white transparent solid substance. It is an amorphous form. Silica gel is a highly active, porous material with a large internal surface area and an internal surface area of more than 450 m2 per g of silica gel. Therefore, it has a strong adsorption property to liquid or gas.
