PAT700 TOC Analyzer Excursion Mode

Maintaining control of pharmaceutical water systems requires more than meeting TOC limits—it demands the ability to quickly understand why deviations occur. Transient TOC excursions, even those below action thresholds, can be early signals of microbial growth, biofilm formation, filter degradation, or residual cleaning agents. Regulatory guidance from USP, Ph. Eur., FDA, and EU GMP Annex 1 reinforces the need for continuous monitoring, timely investigation, and documented root cause analysis. Excursion Mode on the PAT700 TOC Analyzer is designed to close the gap between detection and investigation. By automatically capturing water samples at the moment a TOC or conductivity alarm occurs, it preserves the true conditions of the event.

See how this approach helps teams distinguish false positives from real quality risks, streamline investigations, and maintain a validated state with greater confidence.
