LAR's QuickTOCuv is a continously analyser for the determination of total organic carbon (TOC) and the dissolved organic carbon (DOC) in pure, drinking, surface and waste water.

The QuickTOCuv uses the persulfate method, wherein the TOC is oxidized by UV light and a digestion reagent. Subsequently, the resulting CO2 measured by a NDIR detector. The method is suitable for the determination of TOC in pure water (drinking water, condensate, boiler feed water) because of the technical processing not all particles can be completely oxidized.
