SAMP22-Type II anion exchange resin

SAMP22 Is a premium grade macroporous type 2 strong base anion exchange resin with polystyrene matrix and type II quaternary amine (Dimethylethanolamine) function group.

The particle size is in standard gaussian distribution with 0.315-1.25mm >95%.

SAMP22 has macroporous structure and type 2 strong base, which offers excellent resistance to osmotic & mechanical shock, high chemical regeneration efficiency and good resistance to fouling. it is intended for use in the chloride form for removal of alkalinity and organics such as fulvic and humic acids, as well as in the hydroxide form for all types of deionizing systems.

Compared with type 1, SAMP22 have not taste and odor, so it is also recommended to use for the demineralization system where amine odor is undesirable.

SAMP22 is supplied in the chloride form or SAMP22 OH in the hydroxide form
