LAR’s QuickTOCuv is an online TOC analyzer for the continuous determination of total carbon (TC), total organic carbon (TOC), non-purgable organic carbon (NPOC), and dissolved organic carbon (DOC) in solid-free water such as pure, drinking, surface and process water.
The process control has been optimized for high performance. The correct function of the NDIR detector is automatically checked on a regular basis by a zero point correction and sensitivity tests. This ensures that deviations are quickly detected and guarantees precise results.
