TR-1800 Total Nitrogen Rapid Analyzer

Detection principle:

The TR-1800 total nitrogen analyzer from Tongao brand uses a closed digestion tube and potassium persulfate as an oxidant to convert all nitrogen-containing compounds in the sample into nitrate at 125 ℃. It then reacts with a color reagent under acidic conditions to form a complex. The absorbance is measured using UV absorption spectrophotometry, and the total nitrogen content (mg/L) is directly displayed after calculation by a microcomputer chip.
