Pure products with ultrapure water

Total organic carbon (TOC) is an important quality parameter in the manufacture and use of ultrapure water. If the TOC content is too high, it can affect the performance of a water treatment system or contaminate batches of pharmaceuticals, for example. The online TOC analyser CA79 from Endress+Hauser offers continuous, precise monitoring of the TOC content in ultrapure water, providing life sciences companies with an assurance that their water for injection (WFI) is not contaminated and that product batches are safe and conform to regulations. Real-time overview of water quality The TOC analyser CA79 operates with the proven UV‑oxidation process and differential conductivity measurements. With a response time of 50 seconds, it consistently delivers reliable, precise measurement values so users can immediately recognise if the quality of the ultrapure water has deteriorated. They can then react immediately to prevent contamination of the end product, thus reducing product loss and costs. Pharma-compliant The CA79 fulfils the requirements of the European and US Pharmacopoeia, enabling manufacturing activities in accordance with FDA 21 CFR Part 11. Depending on the configuration, calibration and system suitability tests (SSTs) can be initiated at the push of a button and run automatically, including data analysis. Regular SSTs ensure verification of the TOC values in line with the requirements of the Pharmacopoeia. With its compact stainless steel housing, the CA79 integrates seamlessly into ultrapure water installations, and ensures the analyser is suitable for use in applications subject to the

stringent hygiene requirements of the pharmaceutical industry.

Complete measuring point management

The analyser’s modular design and good accessibility to all components ensure easy maintenance and low operating costs. And the Endress+Hauser worldwide service network offers complete measuring point management, including installation qualification (IQ) and operational qualification (OQ). With the introduction of the TOC analyser CA79 for low measuring ranges,

TOC analyser CA79 for low measuring ranges in pure or ultrapure water.

Endress+Hauser extends its portfolio for liquid analysis in the life sciences sector. With the Memosens CPS61E pH sensor, the Memosens COS81E oxygen sensor and the Memosens CLS82E conductivity sensor, the company launched sensors in the past year for the most critical measurement parameters. The latest generation of the Memosens sensor – Memosens 2.0 – is characterised by especially precise and stable measurement values and adheres to the highest hygiene and regulatory requirements. The sensors enable expanded storage of the process, calibration and sensor data and offer more precise process control and documentation, especially for regulated industries. That means customers have a complete portfolio of sensors, photometers and TOC analysers available to them to equip all required measuring points from a single source.
