The multi N/C UV HS is a wet chemical TOC analyzer which works both with an oxidation agent (peroxodisulfate) and a highly effective UV radiation source for sample oxidation. At the same time the system is highly sensitive and suitable – along with ultra-pure water samples – also for drinking water or special samples, such as acids, electrolysis baths and other aggressive matrices. Unlike classical TOC analyzers with an UV reactor, multi N/C UV HS uses two wavelengths instead of just one: 254 nm and 185 nm. The hard radiation obtained in this way guarantees a complete oxidation of even the most stable carbon compounds.
