MB-5USTD (Low TOC) resin is designed to produce ultra-pure water required for many applications such as for micro-eletronic and pharmaceutical productions. The component resins are specially selected to ensure ultra-pure water production, low conductivity, and low effluent TOC values (<10 ppb after initial rinse).
The product is a special blend of Type II strong base gel type anion exchange resins (A302U, OH) with 8% crosslinked strong acid porous gel type cation exchange resins (C108U,H). The Type II anion resin, regenerated in the high-purity form, is free of the “fish” smell that might be detected from a mixed-bed product with Type I anion resin. This advantage makes the MB-5 series of mixed-bed products (with Type II) more suitable for food-grade applications.
