Analysers for monitor low-TOC values precisely and reliably

Endress+Hauser augments its liquid analysis portfolio in the life sciences, power & energy, semiconductor manufacturing, personal care, and disinfectant production sectors with the CA78 and CA79 online TOC analysers, ensuring high water quality and safe operating conditions.

Total organic carbon (TOC) is an important quality parameter in the various manufacturing and process environments that depend on ultrapure water. When TOC content is too high, it can adversely impact the performance of water treatment systems, compromise high-precision machinery, or contaminate batches. The CA78 and CA79 online TOC analysers provide continuous and precise monitoring to ensure stable operations, regulatory compliance, and high-quality products.

Real-time water quality assessment for minimal product contamination

These TOC analysers utilise UV-oxidation and differential conductivity measurement, the most-established method for reliable TOC trace analysis in ultrapure water. The fast response time (t90) of 50 seconds enables quick control system and personnel reaction in the event of water quality deterioration, reducing contamination, product loss, and costs.

Complete measuring point management

The analysers’ user-friendly modular design and easy accessibility to components simplify maintenance and minimise operating costs. Additionally, Endress+Hauser’s worldwide service network provides end users with complete measuring point management throughout plant lifecycles, including installation qualification and operational qualification.

The CA78 TOC analyser supports safe operations in many applications, including but not limited to:

· Protecting turbines and other expensive power plant equipment

· Manufacturing semiconductors and additional microelectronics

· Ensuring product quality in the personal care industry

· Assuring the efficacy of disinfectants

The CA78 is configurable to meet various requirements in the power and semiconductor industries. For example, the standard version is the right choice for measuring ultrapure water in semiconductor production, providing high-precision measurement in water with conductivity values up to 2µS/cm. Meanwhile, the instrument option for measurement in water with conductivity values closer to 10µS/cm is perfectly-suited for deionised water in power plants. When multiple TOC measuring points are required, the three-channel configuration allows for multiple streams to be run through one analyser, which reduces capital expenditures.

Pharma-compliant CA79

The CA79 TOC analyser meets or exceeds all requirements of the US and European Pharmacopoeias, enabling manufacturing activities in accordance with FDA 21 CFR Part 11. Depending on the instrument configuration, online calibration and system suitability tests (SSTs) can be initiated with the press of a button, and these records are automatically stored onboard.

Regular SSTs ensure compliance with the pharmacopoeias’ regulations for TOC values. And with a compact, stainless-steel housing, the CA79 integrates seamlessly into ultrapure water installations, ideally situating it for use in applications subject to the stringent hygiene requirements of the life sciences industry.

With the introduction of the CA78 and CA79 analysers for low-TOC measurement ranges, Endress+Hauser is rounding out its liquid analysis solutions for critical parameter measurement.

The CA78 supplements Memosens CLS15E contacting conductivity sensors, Liquiline System CA80SI silica analyzers, CA76NA sodium analyzers, and SWAS panels for reliable, low-maintenance solutions in a variety of sectors. The CA79 complements the Memosens CPS61E pH sensor, Memosens COS81E oxygen sensor, and Memosens CLS82E conductivity sensor for critical parameter measurement in pharmaceutical production environments.

These analysers each store critical process, calibration, and sensor data locally, with transmission to a central process control and documentation hub, which is especially important in highly-regulated industries. This plethora of high-precision instruments provides end users with a complete portfolio of sensors, photometers, and TOC analysers, and now all of these measurements can be monitored and managed at a single source.
