On-Board Monitoring of SO<sub>2</sub> Ship Emissions Using Resonant Photoacoustic Gas Detection in the UV Range
A photoacoustic gas detector for SO<sub>2</sub> was developed for ship exhaust gas emission monitoring. The basic measurement setup is based on the absorption of electromagnetic radiation of SO<sub>2</sub> at 285 nm wavelength. A commercially available ultraviolet (UV) light-...
