Description

Application

Weakly basic anion exchange resin that is well suited for combined use with strong base anion resins for water with high concentration of mineral anions or high organic fouling potential. It is excellent for all demineralization applications, and meets requirements of FDA Food Additive Regulation 21 CFR 173.25.

Features and Benefits

Weakly basic anion, macroporous

Other Notes

Monodispersed beads make this resin superior and more efficient than the Dowex MWA-1.

This ion-exchange resin has not been specially processed nor cleaned. We suggest that it be treated to a suitable preliminary elution and wash.
