The photochemical oxidation. Using TOC determination.

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

The TOC is one of the most important composite parameters in the assessment of the organic pollution of water.
