Geduran® Si 60, 40 - 63 µm

Supplier: Merck

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.

LiChroprep® is a proven, highly successful packing material providing fast, effective and reproducible separations.

Supplier: Merck

Composed of magnesium and silicon oxides in the approximate ratio of 85:15. This is a polar phase used for the chromatography of compounds such as steroids and alkaloids. This activity can be controlled by the activation temperature used.

Supplier: MP Biomedicals

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.

Supplier: Merck

Selection of Merck's standardised and modified silica gels that are available in many granulations and supplied from one single source, dedicated to chromatography. Standardised silica gels are widely used in separation processes to purify valuable compounds in ton quantities. Modified silica on the other hand is used in separation problems, which cannot be adequately solved using unmodified silica.

Supplier: Merck

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.

Supplier: Merck

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.
