uniTOC total organic carbon analyzer from water to ultra pure water

The uniTOC system is designed for total organic carbon (TOC) online/ offline monitoring from water to ultra pure water. The uniTOC instrument uses the full oxidation by UV. The oxidation process can be enhanced with additional dosage of reagent. The NDIR detector (non dispersive infrared) is absolutely selective to carbon dioxide and therefore independent from conductivity and sample temperature. In a first step the TIC (total inorganic carbon) is removed with carbon dioxide free stripped gas and after that the TOC value is measured.
