Residual Solvent Class 1 - 1,2-Dichloroethane, Reference Standard

Artikel-Nr: (1601180.)

Lieferant: USP

Beschreibung: USP Reference Standards are specified for use in conducting official USP–NF tests and assays. USP also provides Reference Standards specified in the Food Chemicals Codex as well as authentic substances—high-quality chemical samples—as a service to analytical, clinical, pharmaceutical and research laboratories. To confirm accuracy and reproducibility, USP Reference Standards are rigorously tested and evaluated by multiple independent laboratories including USP, commercial, regulatory, and academic labs. USP also provide publicly available, official documentary standards for pharmaceutical ingredients in the USP–NF that link directly with our primary reference standards.

Silica adsorbents for chromatography, EcoChrome™, MP Biomedicals

Artikel-Nr: (ICNA0204663)

Lieferant: MP Biomedicals

Beschreibung: 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.

Cellulose für präparative Chromatographie

Lieferant: Merck

Beschreibung: 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.

Bulk media for ion exchange chromatography columns, PL-SCX

Lieferant: VARIAN

Beschreibung: 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.

Florisil® für die präparative Chromatographie

Lieferant: Merck

Beschreibung: Besteht aus Magnesium- und Siliziumoxiden im Verhältnis 85:15. Dies ist eine polare Phase, die für die Chromatographie von Verbindungen wie Steroiden und Alkaloiden verwendet wird. Diese Aktivität kann durch die verwendete Aktivierungstemperatur gesteuert werden.

Aceton, LiChrosolv® für die HPLC, Supelco®

Lieferant: Merck

Beschreibung: With their high degree of UV transmittance, low particle count, low acidity and alkalinity and low evaporation residue level, LiChrosolv® solvents are ideal for reproducible separations. Since separations are normally carried out under gradient conditions in analytical HPLC, we offer solvents in "gradient grade" as well as "isocratic grade". This enables to minimize the gradient effect of the solvent involved.
