Principle

When the sample flows in to the analyzer, the ammonium phosphorus molybdate that is created through reaction of phosphate ion in the sample with ammonium molybdate is reduced by ascorbic acid (C₆H₈O₆)to generate the color of molybdenum blue. Here, phosphate phosphorus is quantified by measuring the blue absorbance of molybdenum blue at 880nm. Depending on the sample water conditions of the site, the measurement wavelength can be set to 710nm.
