ALDEX CSR Series
Chromatographic Separation Resin: C106 (Ca/K)
Aldex C106 (Ca/K) is a gel-type, strong acid cation resin supplied in the Calcium ion (Ca2+) or Potassium ion (K+) form. It is specially designed as a universal media for the physical separation of ingredients for the food and beverage industry and is primarily used in simulated moving bed (SMB) chromatographic systems for the recovery and purification of high fructose corn syrup (HFCS) and high-purity fructose.

Aldex C106 (Ca/K) Features
Highest Recovery and Purity
Aldex C106 (Ca/K) resins provide the highest recovery and purity for starch-based sweeteners as well as the purification of polyols.
Uniform Particle Size
Aldex C106 (Ca/K) resins are strong acid cation resins manufactured in a process that produces an extremely uniform particle size.
Efficiency
The consistency of Aldex C106 (Ca/K) resins, with their rapid kinetic properties, provide improved efficiency in sweetener separations over that of standard-grade resins.
Very low color/taste/odor
Aldex C106 (Ca/K) resins meet the requirements for paragraph 173.25 of the Food Additive Regulation of the U.S. Food and Drug Administration.
Superior Physical Stability
The swift kinetics and highly uniform particle size provide resistance against bead breakage with ≥ 97% whole, uncracked beads.
Long Life
Strong and durable beads ensure long service life.
Safety Information
A material safety data sheet is available for Aldex C106 (Ca/K) resin. Copies can be obtained from Aldex Chemical Co., LTD. Aldex C106 (Ca/K) resin is not a hazardous product and is not WHMIS controlled.
Caution: Acidic and basic regenerant solutions are corrosive and should be handled in a manner that will prevent eye and skin contact. Before using strong oxidizing agents in contact with ion exchange resin, consult sources knowledgeable in the handling of these materials.

Backwash Characteristics
Estimated bed expansion as a function of backwash flowrate at 77°F (25°C) is represented in Fig. 1. To find the flow rate necessary for the desired bed expansion at other water temperatures, this equation can be used:
FT = F77ºF [ 1 + 0.008 (TºF – 77) ], where F ≡ gpm/ft2
