Analyzers for monitoring low TOC values
The CA78 (photo) and CA79 online total organic carbon (TOC) analyzers provide continuous and precise monitoring to ensure stable operations, regulatory compliance and high-quality products. These TOC analyzers utilize ultraviolet (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 s enables quick control system and personnel reaction in the event of water quality deterioration, reducing contamination, product loss and costs. The CA78 is configurable to meet various requirements in the power and semiconductor industries. For example, the standard version measures ultrapure water in semiconductor production, with conductivity values up to 2µS/cm. Instrument options for measurement in water with conductivity values closer to 10µS/cm is suitable for deionized water in power plants. The CA79 TOC analyzer meets or exceeds all requirements of the U.S. and European Pharmacopoeias, enabling manufacturing activities in accordance with FDA 21 CFR Part 11. — Endress+Hauser, Greenwood, Ind.
