| abstract | An object of the present invention is to improve the measurement accuracy when measuring the concentration of nitrate nitrogen in a sample containing nitrite nitrogen and nitrate nitrogen using a reduction column. A sample containing nitrite nitrogen and nitrate nitrogen is reacted with a coloring reagent that reacts only with nitrite nitrogen to detect a first absorbance (steps S13, S14, S17), and the sample Is allowed to pass through a reduction column and then reacted with a coloring reagent to detect a second absorbance (steps S15 to S17). The first absorbance is corrected using the absorbance change rate で あ る, which is the ratio of the absorbance obtained through the reduction column to the absorbance obtained without passing through the reduction column, and the corrected first absorbance From the difference between the second absorbance and the characteristic information detected in advance, the concentration of nitrate nitrogen in the sample before passing through the reduction column is measured (step S18).
