Aluminum Oxide Chromatography Aluminium Oxide for Chromatography is a white to off white, fine-grained powder, highly porous form of aluminum oxide. Its surface is more polar than that of silica gel and reflecting the amphitrical nature of aluminium, has both acidic and basic characteristics. The chromatographic characteristics are determined by its specific (internal) surface area measured by the BET Method, its mean pore diameter, and its pore volume, the latter two being in relation to the specific surface area. Sorbead India assures to supply the highest quality chromatography sorben

Silica Gel Column Chromatography All chromatographic methods -with the exception of TLC- use columns for the separation process. Column chromatography has found its place in many laboratories for preparative purposes as well as for reaction control in organic syntheses. The importance of column chromatography is mainly due to following factors Simple packing procedure Low operating pressure Low expense for instrumentation Column chromatography is separated into two categories, depending on how the solvent flows down the column. If the solvent is allowed to flow down the column by grav
