Column Selection : by Separation Mode

Aqueous SEC (GFC) columns are mainly used for the analysis of saccharides such as starch. However, for the analysis of saccharides in the low molecular weight range with molecular weights similar to each other, GFC mode alone cannot provide satisfactory separation. Shodex columns for saccharides analysis have ligand exchange, ion exchange, ion exclusion, reversed/normal phase and GFC mode combined; these columns are suitable for the analysis of various types of saccharides.

For high-selective analysis of organic acids, affinity chromatography columns, AFpak series columns are recommended.
