VDet-500 Total Nitrogen water Quality Automatic Analyzer

Product Description

Under more than 60°C in aqueous solution, potassium per sulfate can be completely decomposed into potassium bisulfate and atomic oxygen and at 120°C~124°C conditions, the automic oxygen can make the nitrogen of nitrogen compound in water samples element oxidize to nitrate,andorganic matter are also oxidized and decomposed simultaneously. The absorbance of water samples is measured by UV spectrophotometer at the wavelength of 220nm and 275nm.Total nitrogen content is calculated according to this absorbance.
