Separation Resin Primarily Used for Crystalline Fructose, Sugar Alcohols, and Novel Separations

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 280-μm members of the AmberLite CR99 family are specifically designed with the combination of particle size and rapid kinetics to maximize SMB performance and minimize product dilution, while keeping pressure drop acceptable for many existing separation systems that utilize 310- or 320-μm beads. The enhanced performance helps to minimize water evaporation costs and is especially valuable in
difficult sweetener separations such as high-purity dextrose, crystalline fructose, specialty sugars, and polyols/sugar alcohols.

AmberLite™ CR99 Ca/280 Chromatographic Separation Resin is used for high purity fructose and polyols/sugar alcohols, and could be considered in some systems for the separation of glucose and fructose in the production of high fructose corn syrup (HFCS).

Can be used with AmberLite CR99 K/280 Chromatographic Separation Resin,  Either ionic form can be used in other specialty separations, depending on the binary pair of constituents.
