DuPont™ AmberLite™ FPA98 Cl Ion Exchange Resin

 
 
 

DuPont™ AmberLite™ FPA98 Cl ion exchange resin is a macroporous, strong base anion exchange resin, supplied in the Cl-form. The acrylic composition of the matrix provides decolorization of highly colored (greater than 500 ICUMSA) liquid sugar with excellent desorption of the organic color bodies during regeneration, reducing the fouling associated with other types of resin such as those based on crosslinked polystyrene.   This resin is also used for chromatographic purification of crude and fine heparin in the pharmaceutical industry.

AmberLite™ FPA98 Cl Resin exhibits excellent resistance to physical breakdown by attrition and osmotic shock.  The robustness of AmberLite™ FPA98 Cl resin makes it a good option as an initial crude purification technique in multi-step purification trains or as a guard bed for polishing operations.  In sugar decolorization, it can be used alone as a gross decolorization resin for highly-colored sugar solutions or in combination with AmberLite™ FPA90 Cl Ion Exchange Resin where the latter is used as a polisher for very low color final products. This use of ion exchange based decolorization technology has proven more effective and economical than carbon or bone char based technologies for sugar solutions.
