Liquid FT-IR photoacoustic detector for elimination of water-vapor interference
A liquid photoacoustic detector suitable to Fourier transform infrared (FT-IR) spectrometer with a condenser microphone as coupling unit is described in this paper. The experiments with the use of this detector show that the interfering signal arising from vapor absorption can be eliminated. We also present a better method for measuring FT-IE spectrum of aqueous sample in this paper.
