DuPont™ AmberTec™ MR-300 UPW H/OH Ion Exchange Resin
Separable, Uniform Particle Size, Mixed Bed Ion Exchange Resin for Demineralization Applications and Final Polishing for the Semiconductor Industry
Description
DuPont™ 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%). As shown in Figure 2, the excellent rinse characteristics also allow very efficient online operation.
Applications
– Regenerable, polishing mixed bed
– Working mixed bed following reverse osmosis
– Non-regenerable, polishing mixed bed
AmberTec™ MR-300 UPW H/OH Ion Exchange Resin has previously been sold as DOWEX MONOSPHERE™ MR-3 UPW Ion Exchange Resin.
