The monitoring of nitrogen oxides (NOX) is prescribed by European directives by means of chemiluminescence. This paper presents the activity carried out at INRiM for the preparation and analysis of NOX mixtures, with the aim of establishing metrological traceability. Together with the use of chemiluminescence, the application of Fourier Transform Infrared (FTIR) spectroscopy is also under investigation as it can allow the identification of some impurities occurring in the gas mixtures which cannot be discriminated by chemiluminescence.
