Wako, 010-01525, Alumina, Activated

Activated alumina is produced by dehydration of hydrated alumina gel at 300 to 500 degrees C. It has strong absorption capacity for water and gas, etc., and is used as an adsorbent, desiccant, and catalyst, (in particular as a dehydration catalyst). Its crystalline form is gamma-alumina.Activated alumina is classified into acidic (pH 4), basic (pH 9), and neutral (pH 7.5) types. The product belongs to the basic type., Column chromatography is generally used for preparative isolation and purification of medium to large scales. We offer a wide variety of matrix and modified supports that can be used for separation of not only organic compounds but also of natural products and biopolymers.Alumina support for absorption and reverse chromatographyThese are suited for separation of neutral and basic materials and are widely used for separation of alkaloids, steroids, aldehydes, ketones, and aromatic hydrocarbons. The degree of activation differs greatly depending on the water content of the adsorptive support.
