Stationary source emissions. Determination of mass concentration of nitrogen oxides. Standard reference method. Chemiluminescence1 Scope This European Standard specifies the standard reference method (SRM) based on the chemiluminescence principle for the determination of the nitrogen oxides (NOx) in flue gases emitted to the atmosphere from ducts and stacks. It includes the sampling and the gas conditioning system, as well as the analyser. This European Standard specifies the characteristics to be determined and the performance criteria to be fulfilled by portable automated
