1. method, it comprises:

  • With first sample dehydration of hydrocarbon gas mixture, to reduce its water vapor concentration;

    Write down first absorption spectrum of described first sample at specified wavelength;

    Write down second absorption spectrum of second sample of described hydrocarbon gas mixture;

    Produce difference absorption spectrum by described first absorption spectrum and described second absorption spectrum;

    AndAnalyze described difference spectrum to determine the concentration of water vapour in the described hydrocarbon gas mixture.
