AmberLite FPA40 Cl can be used as an alternative to AmberLite FPA98 Cl or AmberLite FPA90 Cl to decolorize sugar solutions < 200 ICUMSA.

Whilst a gellular resin, the high moisture content exhibits some of the characteristics of a macro-reticular resin which make AmberLite FPA40 Cl ideally suited to the reversible uptake of organic color bodies commonly found in sucrose syrups.
AmberLite FPA40 Cl is a very unique product in that it is a gellular resin (high capacity) with macroreticular characteristics (physical stability). It is an excellent resin of choice for Decolorization of organic color bodies in many bioprocessing applications, including
natural product extraction and recovery / decolorization of antibiotics from fermentation broth.

It is extensively used in aminoglycoside purification processes in combination with AmberLite FPC3500, and/or AmberLite CG50 type 1.

Thanks to AMBERITE FPA40 Cl, higher level of purity of aminoglycoside antibiotics can be achieved in a decolorization step either pre- or post- purification.
