Separation Resin Primarily Used for Size Exclusion Chromatography such Beet Molasses Desugarization and Dextrose Purification

AmberLite CR99 Chromatographic Separation Resins are strong acid cation resins manufactured in a process that produces an extremely uniform particle size. This family of resins was specifically developed for use in simulated moving bed (SMB) chromatographic systems for the recovery and purification of sweeteners.
The 320-μm members of the AmberLite CR99 family are specifically designed with the combination of particle size and rapid kinetics for excellent separator performance. For decades it has demonstrated reliability in sweetener separations for the production of
beet sugar and high-purity dextrose.

AmberLite CR99 K/320 Chromatographic Separation Resin is used in chromatography for beet molasses desugarization and high-purity dextrose production.

Either ionic form, or the available Ca-form 320-μm chromatographic separation resin, can be used in other specialty separations, depending on the binary pair of constituents.
