Aluminiumoxid för preparativ kromatografi

Leverantör: MERCK PRODUCTION CHEMICALS

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