TL;DRAbstract

Nitric oxide (NO) and Nitrous Oxide (N2O) are compounds that play a significant role in many different fields. They are an important greenhouse gases and they are also characteristic compound which is emitted by most explosive materials. In the air the nitrogen oxides occur mainly as a mixture of stable NO2, N2O and NO molecules. Their reactions with H2O lead to acid rains. Atmospheric photochemistry induces a complicated conversion mechanism of between nitrogen oxides. NO and N2O are also the main products of thermal decomposition of vapors of specific explosives. Most explosives are nitro compounds (i.e. containing a nitro group NO2), which emit (chemically or biochemically) trace amounts of nitrogen oxides (including NO and N2O). There are many methods using for NO and N2O detection. For example, in the case of gas chromatography (GC) and mass spectrometry (MS), detection limit of a few dozen of ppb is reported [1, 2]. These gases can be also detected using photoacoustic methods wit
