Cosmosil
5NH2-MS
Saccharides
cannot be separated using standard HPLC columns, because these
compounds possess low hydrophobicity and are not retained.
It is also difficult to obtain good separation even if the
compounds are retained, because the composition and structure
of these molecules are very similar. The COSMOSIL 5NH2-MS
aminopropyl column is highly recommended for the effective
separation of monosaccharides and oligosaccharides. These
columns are also recommended for adsorption chromatography.
