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 PRODUCTION CHEMICALS

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.

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.

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.

PL-SCX is a macroporous PS/DVB matrix with a very hydrophilic coating and strong cation exchange functionality. The manufacturing process is controlled to provide optimum density of strong cation-exchange moieties for analysing, separating, and purifying a wide range of biomolecules from small peptides to large proteins.

Supplier: VARIAN

The PL-SAX media are well suited for anion exchange HPLC separations of proteins, peptides, and deprotected synthetic oligonucleotides. Denaturing conditions of temperature, organic solvent, and high pH levels are used for the oligonucleotide separations.

In general, ion exchangers consist of a cross-linked polymer matrix with a uniform distribution of fixed ionic groups sited throughout the resin structure. These must be balanced by a similar number of ions of the opposite charge, (counter ions) to maintain electrical neutrality. Cation exchangers therefore, exchange and enrich only cations, anion exchangers only anions. In contrast adsorber resins have a non ionic, but depending on the structure, a somewhat polar character, and don't adsorb stoichiometrically both: anions, cations, as well as uncharged compounds.
