These particles have a perfect spherical shape and are available in two particle sizes: 10 and 20 μm. Together with a pore diameter of 100 Å (10 nm), these new sorbents fit perfectly into the polishing step of small peptides like insulin and other biopharmaceutical and pharmaceutical APIs like antibiotics and hormones. This highly porous silica is produced by spray drying.

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.

Selezione di gel di silice standardizzato e modificato della Merck, disponibili in diverse granulometrie e forniti da un'unica fonte, dedicata alla cromatografia. I gel di silice standardizzati sono ampiamente utilizzati nei processi di separazione per purificare composti di alto valore in grandi quantità. D'altra parte, la silice modificata è utilizzata nel caso di problemi di separazione che non possono essere risolti in modo adeguato utilizzando silice non modificata.
