Application
DOWEX MONOSPHERE 550A UPW (OH) type 1 strong base anion exchange resin is recommended for the roughing, intermediate and polishing ion exchange applications. Low TOC levels in the UPW grade are achieved by deliberate functionalization and rinsing. UPW grade is characterized by its light color, superior crush strength, and high (greater than 95%) conversion of exchange sites to the hydroxide (OH) form.
