Description

Separation Resin Primarily Used for Size Exclusion Chromatography such as Betaine Purification

AmberLite CR99 Chromatographic Separation Resins are gel, 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 310-μm members of the AmberLite CR99 family are specifically designed with the combination of particle size and rapid kinetics to improve SMB performance and minimize product dilution. The improved separator performance helps to minimize water evaporation costs and is especially valuable in sweetener separations such betaine purification and polyols/sugar alcohols.

AmberLite CR99 Na/310 Chromatographic Separation Resin is used in lactose removal in dairy operations and glucose recovery.

Either ionic form, or the available Ca-form 310-μm chromatographic separation resin, can be used in other specialty separations, depending on the binary pair of constituents.
