Uniform Particle Size, Gel, Strong Base Anion Exchange Resin for Single Bed and Mixed Bed Demineralization Applications for the semiconductor Industry.

AmberTec UP4000 OH Ion Exchange Resin is a semiconductor-grade, uniform particle size, gel, strong base anion resin developed specifically for use in producing ultrapure water for the semiconductor industry
It is intended for use in regenerable primary or polishing mixed beds, and it is sold in the fully-regenerated hydroxide form to ensure minimum impurity leakage. AmberTec UP4000 OH is designed to be paired with cationic AmberTec UP1400 H Ion Exchange Resin for mixed bed applications. Its high exchange capacity makes AmberTec UP4000 OH the product of choice for the removal of trace boron post-reverse osmosis in single beds regenerated with NaOH.
AmberTec UP4000 OH can also be used as the anion exchange resin component of a non-regenerable polishing mixed bed to achieve the lowest possible leakage of ionic species, silica, total organic carbon (TOC), and sub-micron particles.
