The multi N/C UV HS is a wet chemical TOC analyzer. This highly sensitive system works with an oxidation agent (peroxodisulfate) as well as with a highly effective UV radiation source for sample oxidation. The system is suitable for drinking water or special samples, such as acids, electrolysis baths and other aggressive matrices. The multi N/C UV HS utilizes two wavelengths instead of just one, which are 254 nm and 185 nm. A complete oxidation of the most stable carbon compounds is guaranteed by using this hard radiation. Minimal system blank values are ensured by the automated purging of the reagents which effectively reduces the blank value.
