Separation Resin Primarily Used for 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 220-μm members of the AmberLite CR99 family are specifically designed with the particle size to provide rapid kinetics, yielding better separation in difficult-to-separate and high-value sweeteners, making it the premium resin for water use reduction and helping to reduce energy costs associated with evaporation. When installed in shallow bed separators, it can provide exceptional performance compared to a resin with larger beads.

AmberLite™ CR99 K/220 Chromatographic Separation Resin is used in the
separation of polyols/sugar alcohols.

Can be used with AmberLite CR99 Ca/220 Chromatographic Separation Resin,  Either ionic form can be used in other specialty separations, depending on the binary pair of constituents.
