Field of application
The total organic carbon (TOC) content is an important quality parameter in the production and use of ultrapure water. If the TOC content is too high, the performance of water purification systems can be impaired or pharmaceutical batches can even be contaminated. The CA79 online TOC analyzer provides continuous, accurate TOC monitoring of your water for injection (WFI). Your product batches can be produced safely and in compliance with regulations.
The CA79 TOC analyzer is perfectly suited for TOC monitoring of ultrapure water in life sciences applications with the following process conditions:Conductivity < 2 µS/cmneutral pH range
Benefits
Real-time overview of water quality: The CA79 TOC analyzer measures continuously providing a fast response time (t90) of 50 seconds. This enables you to react immediately and to protect your product effectively.The online analyzer uses proven UV oxidation and differential conductivity measurement which has become the most-established method for TOC trace analysis in ultrapure water.Compliance:CA79 meets the requirements of the European and US Pharmacopeias and allows working according to FDA 21 CFR Part 11. CA79 provides clear documentation of relevant events, regular quality reports and system suitability tests (SSTs).The analyzer’s maintenance-friendly design in combination with our worldwide service network offers you complete support for the measuring point, including the installation qualification (IQ) and regular operational qualifications (OQ).
