Analytical Principle

Using potassium persulfate digestion, nitrogen compounds convert to nitrate nitrogen under high temperatures. In acidic conditions, nitrate nitrogen reacts with indicator reagent to form colored complexes. The analyzer detects color changes and converts them to total nitrogen concentration values for output.
