Chromatographic Separation Resin are useful in Chromatography, bioseparations, solid phase synthesis, solid phase extraction and sample preparations. 

used for betaine purification, amino acid purification by Simulated Moving Bed (SMB) Chromatography.
together with CHR suitable for separations which depend on relatively small differences of affinity of the materials being chromatographed. They are designed mainly for use in ion exchange columns and industrial plant. They are not for capillary use in e.g. HPLC equipment.
