Chromatography Sorbents

Supplier: MERCK PRODUCTION CHEMICALS

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.

Supplier: VARIAN

The PLRP-S reversed phase HPLC media delivers the pure oligonucleotides (oligos) required for genomics applications, including quantitative PCR, microarrays, and gene synthesis assays.
