Saccharides are not retained on standard C18 columns because of the low hydrophobicity of compounds. COSMOSIL Sugar-D and NH2-MS are specifically designed for separation of saccharides. COSMOSIL C18-PAQ is recommended for hydrophobic glycosides or saccharide derivatives.

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 the 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.
