For the measurement of TOC LAR developed two devices. First, a TOC analyser for ultra pure water applications with TOC contents 10 µg/l (ppb). This analyser uses an efficient UV lamp for oxidising organic compounds by the direct surface principle in combination with conductivity detection. The new generation of LAR’s QuickTOCuv comprises an option for continuous differential conductivity measurements as well as the detection of the POC.
