PDS Monojet LSF9731 Weak Base Anion Exchange Resin Ion Exchange Resins
SEPLITE® Monojet™ LSF9731 Ion Exchange Resin is an uniform particle size, food grade, weak basic macroporous anion resin with tertiary and quaternary amino groups.
Due to its macroporous structure which enables an excellent adsorption and desorption of acidic and organic substances such as colorants. The resin could be easily desorbed by using caustic soda solution. The strong matrix also ensures its good feature of resistance to osmotic shock.
It is mainly designed for the food industrial application such as acid removal and decolorization of sugar, gelatin, grape must and etc., also can treat potable water based on special care to the new resins initial cycles.
The resins are produced fully in accordance with the FDA (US Food & Drug Administration), also meeting the regulations prescribed under Resolution ResAP (2004) 3 on ion exchange and adsorbent resins used in the processing of foodstuffs.
Please follow our start-up recommendations which is available upon request, when using our products in food applications.

Hydraulic Characteristics
Typical values of pressure drop across a bed of SEPLITE® Monojet™ LSF9731 are given for a range of operating flow rate in Fig. 1. Fig. 2 shows the Bed expansion which is a function of flow rate and temperature. Be cautious to avoid loss by accidental over-expansion of the bed.
Precautions
Resins should be stored in sealed containers or bags where temperature was above 0℃ in dry conditions without exposure to direct sunlight.
Do not mix ion exchange resin with strong oxidizing agents; otherwise it will cause violent reactions.
In case of eyes contact with resins, rinse eyes immediately with plenty of water, and consult a specialist.
Material and samples must be disposed according to local regulations.
Dry polymers will expand when become wetted and may cause an exothermic reaction.
Spilled materials may be slippery.
