Ligand exchange mode or HILIC mode are suitable for the separation of monosaccharides, disaccharides, oligosaccharides and sugar alcohols. SEC (size exclusion chromatography) mode is mainly used for the analysis of polysaccharides such as starch. Ion exchange mode or ion exclusion mode are available for the analysis of amino saccharides and acidic saccharides. Shodex has various columns for saccharides analysis.
