Features Of DuPont AMBERLITE MB 9L H/OH Ion Exchange Mixed Bed Resin

  1. Pre-mixed, balanced ratio of strong acid cation (H⁺ form) and strong base anion (OH⁻ form) resins for consistent high-purity water production.

  2. Optimized particle size distribution and uniform bead structure to minimize pressure drop and maximize service cycle efficiency.

  3. Low total organic carbon (TOC) extractables, supporting ultrapure water (UPW) requirements in semiconductor and pharmaceutical applications.

  4. High chemical stability in repeated regeneration cycles, ensuring long operational life under standard mixed-bed operating conditions.

  5. Designed for rapid and complete regeneration with conventional acid–base regenerants, minimizing rinse time and wastewater volume.

Typical Applications Of DuPont AMBERLITE MB 9L H/OH Ion Exchange Mixed Bed Resin

  1. Final polishing step in high-purity water systems for semiconductor manufacturing.

  2. Ultrapure water (UPW) generation for pharmaceutical-grade water (PW, WFI, or Purified Water per USP/EP).

  3. Critical boiler feedwater polishing in power generation facilities requiring low silica and conductivity.

  4. Lab-scale and pilot-scale deionization systems requiring reproducible, low-sodium, low-silica effluent.

  5. Electronics manufacturing process water where trace ion removal and resistivity >18.0 MΩ·cm are essential.
