Abstract

According to an example aspect of the present invention, there is provided a method of selectively catalytically reducing dinitrogen oxide present in a gaseous sample, comprising: providing a catalyst capable of reducing dinitrogen oxide; bringing the gaseous sample into contact with the catalyst to reduce dinitrogen oxide in the gaseous sample in the presence of the catalyst; wherein as a result of the reduction step, the gaseous sample is adapted for determination of the amount of an isotopic form of CO2 in the gaseous sample.
