From Out-of-Spec Results to Audit-Ready: Controlling Titration in GxP Labs

When titration results fall out of specification, resolving the chemistry is only part of the solution. In regulated pharmaceutical laboratories, it is equally critical to demonstrate control over the workflow that produced the result.
Unexpected OOS (out of spec) often stem from subtle but significant factors like electrode performance issues, matrix interferences, or poorly optimized Karl Fischer parameters. In this case study focused mini course, Eduardo Simões, Titration Product Specialist, walks through the most frequent pitfalls encountered in potentiometric and Karl Fischer analyses and demonstrates practical, standards aligned strategies to correct them at the bench.
Building on these corrective actions, Martin Kobler, Senior Product Specialist for Software, demonstrates how compliant digital controls ensure those improvements are consistently applied and defensibly documented. Through structured user roles, controlled method versioning, secure review workflows, and a comprehensive audit trail, participants will see how software transforms troubleshooting into a repeatable, inspection ready process.
Participants will gain a clear framework for preventing recurring deviations, strengthening data integrity, and maintaining inspection-ready titration workflows. Stick around for a live Q&A to explore how these strategies apply to your own titration challenges.
