Summary

Product identification

AmberLite™ IRN9687 Li/OH Ion Exchange Resin

This product is a mixture of nuclear-grade, macroporous strong acid cation and gel strong base anion exchange resins. It is composed of AmberLite™ IRN9652 H Ion Exchange Resin (converted to the ⁷Li form at ≥99.9% isotopic purity) and AmberLite™ IRN78 OH Ion Exchange Resin, supplied together on a 1:1 equivalent basis.

Applications

• Primary water treatment:
  • Primary coolant purification

Purity

AmberLite™ IRN Ion Exchange Resins are manufactured as nuclear-grade with specific procedures to minimize inorganic impurities and remove soluble organic compounds. This high purity is intended to prevent contaminants and deposits in nuclear systems and avoid increased radioactivity.
