Abstract
To provide an SOanalysis device and analysis method capable of accurately and rapidly measuring the concentration of SOin exhaust gas without pre-processing. The present invention is provided with a light source () for radiating laser light () to exhaust gas () including SO, CO, and HO, a photodetector () for receiving the laser light () radiated to the exhaust gas (), a light source control unit () of a control device () for controlling the wavelength of the laser light () radiated by the light source () so as to be 4.060 μm to 4.192 μm, and a concentration calculation unit () of the control device () for calculating the SOconcentration by infrared spectroscopy on the basis of the output from the photodetector () and a reference signal from the light source control unit ().
