AMBERLITE™ FPA54 Ion Exchange Resin

AMBERLITE™ FPA54 Ion Exchange Resin is a unique, highly porous, weak base, anion exchange resin, based on a crosslinked phenol-formaldehyde matrix. The low-swelling characteristics of AMBERLITE™ FPA54 give it excellent osmotic and physical stability resulting in less product loss and longer product life than conventional styrenic resins in food processing and bioprocessing applications. The hydrophilic phenolic, porous matrix of AMBERLITE™ FPA54 permits the reversible adsorption of high molecular weight, organic, color bodies frequently found in solutions of natural product and fermentation products. AMBERLITE™ FPA54 exhibits a high selectivity for sulfates and phosphates and, therefore, makes it ideal for the treatment of both citric and lactic acids derived from fermentation where it has a long history of use, particularly due to its excellent osmotic stability.
