  • Applications

① Monitoring the inlet and outlet of wastewater treatment plants for documentation and calculation of the measured liquid's cleaning ability 

② Providing the discharges of industrial wastewater treatment plants to determine discharge fees based on the polluter-pays principle

③ Evaluating surface water quality in medical units, river and canal water, laboratories, groundwater, ship wastewater, small watersheds, and coastal water

  • Measuring Principle

SUP Total Nitrogen Analyzer uses potassium persulfate under alkaline conditions to digest the sample at high temperature, and all the nitrogen contained in the sample will be oxidized into nitrate. It measures the absorbance of the digest sample at wavelengths of 220 nm and 275 nm, respectively, and it gets the absorbance A220 and A275. This accurate TN liquiline system analyzer calculates the end absorbance A according to the formula A = A220 - 2A275. On top of that, the instrument can calculate the concentration of total nitrogen in the sample through UV spectrophotometric conversion.
