AmberLite CR99 Ca/320

Summary

Product identification

• Product Name: AmberLite™ CR99 Ca/320 Chromatographic Separation Resin
• Product Type: Strong acid cation resin with uniform particle size, designed for simulated moving bed (SMB) chromatographic systems.
• Manufacturer: DuPont

Description

AmberLite™ CR99 Chromatographic Separation Resins are strong acid cation resins manufactured with an extremely uniform particle size. They are specifically developed for use in simulated moving bed (SMB) chromatographic systems for the recovery and purification of sweeteners. AmberLite™ CR99 Ca/320 is designed for excellent separator performance with optimized particle size and rapid kinetics, serving as an industry standard for decades in sweetener separations. This resin is available in the Ca²⁺ form and other similar resins are available in K-form or Na-form.

Applications

• High fructose corn syrup (HFCS) production
• High-purity fructose production
• Polyols/sugar alcohols separation
• Specialty separations

Oxygen removal from feed streams and elution water is strongly advised to maximize resin life.

Hydraulic Characteristics

Estimated bed expansion and pressure drop data as a function of backwash flowrate and service flowrate, respectively, are provided in figures within the datasheet. Equations are available to calculate these parameters for different water temperatures and syrup concentrations. Thermal expansion as a function of temperature and ionic form is also presented.

Disclaimer: Extraction may miss figures, footnotes, or revisions. Contractual data must match the OEM PDF revision used on the project.
