| Abstract: | UV-VIS-differential optical absorption spectroscopy (DOAS) has become a widely used method to measure gases in stack and the atmosphere. This simultaneously measures the concentrations of SO 2 and NO X pollutants. Their concentration is retrieved by a numerical analysis of the absorption spectra, which often are a combination of overlapping absorption structures of several gases. A new analysis procedure was developed, to determine their concentrations, to estimate the error of the concentrations and to consider the uncertainty gases. This paper studies the typical setup and analysis procedure of a differential optical absorption spectroscopy instrument. |
