詳細

A versatile sorbent for preparative chromatography exhibiting a higher pH stability

特徴および利点

Aluminum oxide 90 active acidic (0.063-0.200 mm) provides users with:

An aluminum oxide crystal structure comprises octahedrally and tetrahedrally coordinated aluminum coupled by oxygen atoms. The surface is covered by free hydroxyl groups. There are different acidic and basic centers that result in anion and cation exchange properties. Aluminum oxide exhibits a higher pH-stability than silica gel, especially in the alkaline range and occurs in various crystal modifications resulting in different pore diameters.
