Producent: MERCK PRODUCTION CHEMICALS

Opis: 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.

Opis: Geduran® Si 60, 63 - 200 µm

MSDS

Producent: MERCK PRODUCTION CHEMICALS

Opis: 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.

Opis: 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.

Producent: MP Biomedicals

Opis: 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.

Opis: LiChrospher® RP-8 ADS, 25 µm

Producent: VARIAN

Opis: 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.

Producent: Merck

Opis: LiChrosorb® is an irregular shaped silica sorbent. LiChrosorb® packing materials offer the compete programme of non-polar derivatives (RP-8, RP-18, RP-select B) and polar derivatives (Si 60 and Si 100).

Opis: 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.

Opis: LiChrospher®, LiChrospher® 100 RP-18, 5 µm, 06

MSDS

Producent: Merck

Opis: 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.

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

Producent: VARIAN

Opis: SepTech™ C18 bulk media, designed for high performance separations at high capacity. The two pore sizes, 60 Å and 150 Å, have been optimised to give high capacity for small molecules and larger natural molecules and peptides, respectively.
