Omschrijving: Selectie van de gestandaardiseerde en gemodificeerde silicagels van Merck die leverbaar zijn in diverse korrelgrootten en worden geleverd door één leverancier, die is gespecialiseerd in chromatografie. Gestandaardiseerde silicagels worden vaak gebruikt bij scheidingsprocessen om waardevolle verbindingen in tonhoeveelheden te zuiveren. Gemodificeerde silica wordt daarentegen gebruikt bij scheidingsproblemen die niet voldoende kunnen worden opgelost met ongemodificeerde silica.

Omschrijving: Micro-crystalline cellulose is a hydrophilic polysaccharide packing material preferred for the raw separation of amino acids and related compounds. Cellulose is also used for the gentle purification of bio-molecules. Because of the organic nature of cellulose, it can only be used in pre-swollen state and under gentle or hydrostatic pressure.

Omschrijving: Silica is highly porous and has a number of distinct crystalline forms (polymorphs) in addition to amorphous forms. It is used as a suspending and thickening agent in pharmaceuticals. It is also used in the extraction of DNA and RNA due to its ability to bind to the nucleic acids under the presence of chaotropes.

Omschrijving: 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.
