Detection principle:
The detection principle of a practical total nitrogen rapid analyzer is to add alkaline persulfate to the sample, which converts the nitrogen in the sample into nitrate nitrogen. Under strong acidic conditions, nitrate nitrogen reacts with the color reagent to form a brownish yellow complex, and its absorbance is measured at a certain wavelength. After calculation by the microcomputer chip, the total nitrogen content (mg/L) is directly displayed.
