    AMBERTEC™ MR-450 UPW H/OH Ion Exchange Resin is an ultrapure watergrade, non-separable, homogeneous, mixed bed resin recommended as a point-ofuse or non-regenerable mixed bed in the polishing loop to achieve sub-ppb levels of soluble silica, boron, sodium, potassium, sulfate, chloride, zinc, iron, and aluminum. This non-regenerable mixed bed resin is used for 2 – 3 years before replacement. This homogeneous mixed bed contains 360-μm cation resin and 590-μm anion resin (mean particle size), thus providing efficient kinetics to achieve a higher operating capacity. The ratio of anion to cation in AMBERTEC™ MR-450 UPW H/OH is volumetrically optimized to achieve maximum removal of boron and silica. UPW-grade is characterized by the high conversion to ionic sites (≥ 95.0%), excellent rinse profiles for conductivity and (delta) TOC (see Figure 2), and superior crush strength.
