CA79 TOC Series The low-range online TOC analyzer

Highest product and process safety due to early contamination detection

Fast response times for immediate reaction and process protection

High system availability thanks to maintenance-friendly design

Compliance with European and US Pharmacopoeia requirements

A reliable online TOC analyzer for fast, continuous monitoring of ultrapure water and WFI, ensuring process safety, product quality and efficient batch release in the pharmaceutical industry.

Fast response times for real-time TOC monitoring in ultrapure water

The CA79 is an online TOC analyzer designed for process monitoring. It complies with the strict requirements of life science and pharmaceutical industries and delivers reliable, real-time monitoring of high-purity water systems, including WFI (water for injection), detecting even trace levels of organic contamination. CA79 requires only a sample flow rate of 14 mL/min and ensures consistent water quality and enables safe, efficient production processes. The robust analyzer offers a wide measuring range from 0.5 - 1000 µg/L (ppb) and features an integrated output relay for reliable collective alarm signaling. Serial number–specific IQ/OQ documentation ensures fast installation and on-site qualification.

Fast response time (t 90 ) of 50 seconds

Optimized for ultrapure water applications (conductivity < 2 µS/cm)

Proven UV oxidation without oxidizing agent combined with differential conductivity measurement

Collective alarms for fault or limit exceedance via 4–20 mA

Maintenance-friendly IP54-rated stainless steel housing

Reliable service network for IQ, OQ and support

21 CFR Part 11 compliant data management with documentation and SSTs (system suitability tests)

Advanced UV oxidation and differential conductivity for high-speed TOC analysis

CA79 applies the principle of differential conductivity detection. The analyzer can continuously read TOC sample levels with very fast response times of only 50 seconds (t 90 ). Therefore, the analyzer is ideally suited to monitor especially time critical process steps in production, distribution and storage of ultrapure water or WFI in pharma and life sciences industries.

Sample digestion is performed by a high-power UV reactor utilizing two oxidation wavelengths simultaneously for fast and complete organic carbon oxidation. High-energy UV radiation at 185 nm and 254 nm are used to oxidize even extremely stable organic compounds completely to CO 2 without any oxidizing agent.
