Cosmosil (HPLC Column)
Reversed Phase Chromatography Octadecyl Types COSMOSIL MS-II, AR-II, PAQ
COSMOSIL 5C18-MS-II is a monomeric type of C18 phase. A new end capping treatment with polar groups for "shield effect" has extended the pH range and significantly improved peak shape for basic compounds. This phase is recommended for most of applications but particularly effective for low molecular weight organic compounds.
COSMOSIL 5C18-AR-II is a polymeric type of C18 phase. It shows exceptional stability and long lifetime at low pH. Thisphase is recommended for the separations requiring acidic mobile phase conditions. It also shows superior molecular shape selectivity to monomeric type C18 columns.
COSMOSIL 5C18-PAQ is designed to offer superior retention of polar compounds and excellent reproducibility inhighly aqueous mobile phases, even in 100% aqueous.
HPLC Column for Saccharide Analysis COSMOSIL Sugar-D
Conventionally aminopropyl bonded stationary phases are used for liquid chromatographic analysis of mono and oligosaccharides.General shortcomings of the conventional aminopropyl bonded phases are tailing and adsorption of certain saccharides and general low durability (short active life) of these columns. These problems are addressed and solved by the novel COSMOSIL Sugar-D, resulting in better (sharper) separation and much improved durability.
In addition COSMOSIL Sugar-D is useful at the separation of highly hydrophilic compounds which are not retained inconventional octadecyl (ODS) bonded stationary phases.
â¢ Novel stationary phase for saccharides
â¢ Superior durability to conventional amino columns
â¢ Minimized undesirable adsorption.
