Radionuclides and Corrosion Products are captured by these novel ion exchange filter papers, allowing plant personnel to track system and plant performance. Individual, highly functionalized, strongly basic anion and strongly acidic cation exchange papers are produced by a unique patented technology.

This technology achieves very fast ion exchange kinetics and provides the highest available ion exchange capacity per disk. The high performance papers fit all standard 47mm diameter filter holders and are durable, easy to handle, and simple to use.
