Merck bietet für die Präparative Chromatographie standardisierte und modifizierte Kieselgele in mehreren Korngrößen aus einer Hand an. Standardisierte Kieselgele werden bei Trennverfahren verwendet, um wertvolle Bestandteile in Tonnenmengen aufzureinigen. Modifizierte Kieselgele werden dagegen bei komplizierten Trennverfahren eingesetzt, die mit Hilfe nicht modifizierter Kieselgele nicht zufriedenstellend durchgeführt werden können.

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.

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.

Supplier: VARIAN

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.

Supplier: TOSOH Bioscience

These are bulk media products which contain three or four different ligand types offered for a chromatography mode.

Supplier: TOSOH Bioscience

Affinity chromatography resins are functionalised with chemically active groups or group-specific ligands.

Supplier: TOSOH Bioscience

Typically they contain three or four different ligand types offered for ion exchange chromatography mode.

Supplier: TOSOH Bioscience

Hydrophobic interaction chromatography (HIC) is a powerful tool for the process purification of biomolecules. Five HIC ligands featuring different degrees of hydrophobicity and selectivity. The hydrophobicity of HIC resins increases through the ligand series.

Supplier: TOSOH Bioscience

Toyopearl resins can be used in organic solvents or mixtures of organic solvents and water. The compatibility of DMF with Toyopearl also permits the separation of hydrophobic substances such as polystyrenes.
