The behavior of small amounts of nitric oxide in the presence of ammonia and excess oxygen on adsorbents of different textures was studied by gas chromatography. A scheme for the gas chromatographic analyses of the products of catalytic reduction of nitric oxide by ammonia and the catalytic oxidation of ammonia by oxygen was suggested. The scheme makes it possible to prevent chemical reactions between components of the gas mixture analyzed during the accumulation of the products and their analysis, to exclude the partial or complete adsorption of NO on microporous adsorbents, and to monitor the content of components at a level of 500 ppm and lower.
