Application Note: Monitoring TOC in ultra-pure laboratory water
19 May 2008

The serious consequences of organic contamination of ultra-pure water have resulted in the widespread of use of TOC (total organic carbon) monitoring as a key indicator of water purity. TOC is a good indicator of general levels of organic contamination, but due to widely differing organic component levels that could correspond to a particular TOC value, there is no benefit in highly accurate TOC monitoring.

It is far more important to have continuous, on-line TOC monitoring to record changes in organic contamination levels.
