Deciphering VVQ: How Validation, Verification and Qualification Affect Total Organic Carbon Analyzers

By GE Analytical Instruments

With cleaning validation the fundamental question is ,"How clean is clean?" With Total Organic Carbon (TOC) instruments and methods, the question is whether to perform validation, verification, or qualification. Part of the question is not necessarily which mode to use, but, "Does the method or instrument 'suit' its purpose?" Given the current confusion regarding the use of TOC for compendial and analytical method purposes, this paper demonstrates what mode (validation, verification, or qualification) of choice should be used for TOC instrumentation or the methodology.

CheckPoint: A Breakthrough Total Organic Carbon Sensor for Ultrapure Water (UPW) Applications

By GE Analytical Instruments

Accuracy is a key consideration in the proper selection of a TOC device. TOC Sensors exhibit significantly less accuracy than TOC Analyzers, but provide the benefit of lower cost, easier operation, faster analysis and a smaller footprint, therefore choosing a TOC Sensor versus a TOC Analyzer is a matter of intended use. This paper outlines this dilemma, and describes how GE's CheckPoint TOC Sensor optimizes the use of TOC Sensors in diagnostics applications.

A Science-based Performance Comparison of On-line TOC Analyzers

By GE Analytical Instruments

Most pharma companies in the U.S. and Europe use laboratory total organic carbon (TOC) analyzers for the U.S. and European Pharmacopeia compendial TOC release of water to manufacturing in order to improve quality and lower the costs of producing purified water. The basis of a properly designed and qualified on-line TOC-based real-time release (RTR) system is to identify and understand the critical parameters for success. The study described in this white paper by GE Analytical Instruments focuses on the performance capabilities of pharmaceutical on-line TOC analyzers.
