The CA78 and CA79 online total organic carbon (TOC) analyzers from Endress + Hauser provide continuous real-time monitoring using UV-oxidation and differential conductivity measurement. The CA78 comes in multiple configurations—the standard version measures water with conductivity values up to 2 µS/cm. Meanwhile, the instrument option measures water with conductivity values closer to 10 µS/cm. When multiple TOC measuring points are required, the 3-channel configuration allows for multiple streams to run through one analyzer. The pharma-compliant CA79 meets or exceeds all requirements of the U.S. and European Pharmacopoeias, and comes in compact stainless steel housing. Depending on the instrument configuration, online calibration and system suitability tests can be initiated with one button, and the records automatically stored. These analyzers each store critical process, calibration, and sensor data locally, with transmission to a central process control and documentation hub.
