Abstract

The concentration of sulfur dioxide has been measured in the ultraviolet spectral range with a combination of the differential optical absorption technique and Fourier transformation. Measurements have been made with a pathlength of two meters and a measuring time of one minute. Sulfur dioxide levels of less than 0.1 ppm (volume) were assessed with a measurement uncertainty of ±0.03 ppm (volume). This method also shows good robustness against displacements in the wavelength range of the incoming absorption spectrum.
