Description
Separable, Uniform Particle Size, Mixed Bed Ion Exchange Resin for Demineralization Applications and Final Polishing for the Semiconductor Industry.
AmberTec MR-300 UPW H/OH Ion Exchange Resin is an ultrapure water-grade, mixed resin recommended as a working or polishing mixed bed to complement 2-bed ion exchange or reverse osmosis systems. It can be used as a regenerable mixed bed since the color difference and particle size difference will allow a visually good separation to achieve optimal regeneration. Very low ionic load to a regenerable mixed bed
can occasionally lead to clumping, especially when the mixed bed is operated to a boron or silica break. An improvement in the manufacturing process of the anion component will eliminate cation/anion clumping under normal regeneration conditions.
The ratio of anion to cation in AmberTec MR-300 UPW H/OH is volumetrically optimized to achieve maximum removal of boron and silica.
Semiconductor-grade is characterized by the high conversion to ionic sites (≥ 95.0%).
