PROBLEM TO BE SOLVED: To provide a nitrogen compound analyzer for simply and precisely measuring two components of NH<SB>3</SB>and NO<SB>2</SB>or respective components of nitrogen compounds in the same sample. SOLUTION: In the nitrogen compound analyzer having a plurality of sample treatment systems formed by branching one sample and at least one measuring means for continuously measuring nitrogen monoxide in the sample, a switching means capable of switching a treatment system (A) having an oxidation means for oxidizing ammonia in the sample and a conversion means for converting nitrogen dioxide in the sample to nitrogen monoxide, a treatment system (B) having a conversion means for converting nitrogen dioxide in the sample to nitrogen monoxide and a treatment system (C) not applying conversion treatment to a specific component in the sample is provided so as to be capable of switching these treatment systems to a predetermined combination.
