27. d if the spectral analysis program can mathematically solve the spectral overlap There are two reasons for the increase of the signal to noise ratio of an FTIR spectrum e In an FTIR spectrometer the length of the measured interferogram determines the resolution The longer the interferogram the more data points is required and the higher the resolution In a high resolution study the time required by a single measurement is also long so that we are able to accumulate less data in a fixed time leading to higher noise level Thus the longer the measured interferogram is the lower the signal to noise ratio e High resolution requires a small aperture to prevent a phenomenon called aperture broadening Small aperture in turn reduces the signal and thus signal to noise ratio See for example P Jaakkola J D Tate M Paakkunainen J Kauppinen and P Saarinen Instrumental Resolution Considerations for Fourier Transform Infrared Gas Phase Spectroscopy Applied Spectroscopy 51 1997 1159 1169 Gasmet px 4030 USER MANUAL 3 GASMET DX 4030 FTIR GAS ANALYSER 3 1 Introduction The Gasmet gas analysers are divided into four categories On line CX and FCX series On site DX Series In lab CR Series and In situ Series depending on their properties and customers application All Gasmet analysers incorporate a Fourier transform infrared FTIR spectrometer a temperature controlled sample cell except DX 4030 and signal
