Summary
Product identification
AmberLite™ CR99 Ca/220 and K/220 Chromatographic Separation Resins.
Description
These are strong acid cation resins with extremely uniform particle size, manufactured for simulated moving bed (SMB) chromatographic systems. They are primarily used for the recovery and purification of sweeteners. The 220-µm particle size is designed for rapid kinetics, offering better separation of difficult-to-separate, high-value sweeteners, leading to reduced water use and evaporation energy costs.
- AmberLite™ CR99 Ca/220 Chromatographic Separation Resin: Used for the separation of glucose and fructose in the production of high fructose corn syrup (HFCS), high-purity fructose, and polyols/sugar alcohols.
- AmberLite™ CR99 K/220 Chromatographic Separation Resin: Used in the separation of polyols/sugar alcohols.
- Both ionic forms can be used for other specialty separations depending on the constituents.
Applications
- High fructose corn syrup (HFCS) production
- High-purity fructose production
- Polyols/sugar alcohols separation
- Specialty separations

It is strongly advised to remove oxygen from feed streams and elution water to maximize resin life, keeping the concentration below 0.1 ppm (0.25 ppm maximum).
Hydraulic Characteristics
Figures are provided in the original document illustrating:
- Estimated bed expansion as a function of backwash flowrate at 25°C (77°F).
- Estimated pressure drop as a function of service flowrate and HFCS concentration (30% D.S. and 50% D.S.).
- Thermal expansion as a function of temperature and ionic form.
Equations for calculating flowrate for desired bed expansion at other temperatures and for thermal expansion are also provided.
