We present the use of a dielectric barrier discharge (DBD) for the removal of irritant gases. To study the detailed plasma mechanisms, an experimental set-up was constructed that provides a significant concentration of the irritant gas. The gas stream is analyzed with and without plasma treatment using a commercial system based on a quadrupole mass spectrometer. Comparing results of a direct DBD application, treatments in the afterglow and the sole use of UV radiation gives way to identify the plasma species responsible for the reaction. The DBD is applied to the irritant molecule 1-Sulfinylpropane, which is produced from isoalliin by the enzyme alliinase.
