Continuous TOC Measurement
Total organic carbon (TOC) monitoring is vital to Acheson & Acheson, a privately-owned British-based company that designs, formulates, manufactures and supplies cosmetics products to international retailers and global brand owners, including some in the USA. Monitoring TOC is mandatory to meet US Food and Drug Administration regulations, so Acheson & Acheson asked Veolia Water Technologies UK for its advice on selecting a suitable TOC analyzer. Veolia recommended METTLER TOLEDO's TOC analyzers for TOC monitoring, as they use proven ultraviolet oxidation with differential conductivity to effectively determine TOC concentrations.
The analyzers meet the requirements of all major global pharmacopeias for TOC instrumentation, including USP, EP, JP, ChP and IP. The TOC analyzers from METTLER TOLEDO conduct on-line continuous measurements with no batch measurement cycle and no delay. They offer rapid detection of even brief upsets and advanced sensor diagnostics enable predictive maintenance.
Read in the case study how Acheson & Acheson installed the METTLER TOLEDO TOC analyzer to monitor TOC levels as part of a major factory expansion.
Off-line batch measurement as a way of TOC monitoring can only provide a snapshot of TOC levels at the time the sample was taken. If a batch process TOC unit has a response time of 15 minutes, significant and important information may be missed.
Fast, truly continuous measurement of total organic carbon with an on-line analyzer allows real-time water release and ensures rapid detection of even brief upsets to demonstrate full-time compliance with water quality requirements. Detection of TOC from ppm to sub-ppb concentrations enables trending at any level to uncover influences on water treatment system performance.
