摘要：A method of for determining the trace gas concentration in the gas sampleusing Fourier transform infrared spectroscopy. It the described method comprises thefollowing steps: (i), synthetically calibrate a spectroscope, (ii) select a series of candidatewindow to determine a spectral window by (a), be wherein suitble to a spectral tracecalculated to an experimental spectral trace; (b) possible error measure associated witheach serial accessory of spectral trace of candidate window is used for is determined; (c)possible error measure associated with each window for being adapted to determine thatsubstantially the one side with minimum possible error measure is last is utilized; (d)using last window as spectral window. Then it calibrates and spectral window is utilizedthe spectral trace to be suitble to a spectral trace calculated to measure to one byspectroscope and determines the concentration of the gas formed.
