• Figure 2: Pressure Drop (Temperature: 10 – 60°C / 50 – 140°F)

Quality Assurance

AmberTec™ UP4000 OH Ion Exchange Resin is tested by DuPont for resistivity, total organic carbon (TOC), and kinetic performance in a mixed bed with AmberTec™ UP1400 H Ion Exchange Resin to ensure compliance with stringent ultrapure water (UPW) performance requirements. Typical rinse curves for resistivity and TOC are shown in Figure 3.
