Comparative study of the reactive species in the effluent of two different plasma jet devices operated with air as working gas - datasetIn this work, the reactive species generated by two different plasma jet devices operated with ambient air as working gas are studied experimentally and theoretically. One jet device is based in a non-thermal arc, while the other consists of a dielectric barrier discharge (DBD) with two axial electrodes and a double dielectric barrier. Basic electrical characterization was done via voltage and current measurement for both devices with electrical probes and an oscilloscope. The reactive oxygen and nitrogen species present in the jet effluents were measured by Fourier transform infrared absorption spectroscopy (FT-IR). A very different composition of reactive species was found for the two devices. The arc plasma jet has a chemistry dominated by nitrogen reactive species, while the DBD produces mainly ozone. The gas temperature in the discharge region of the two jets was determined by fitting the emission spectrum of the second positive N2 system. The chemical composition in the discharge region was also studied with a theoretical model that considers multiple chemical reactions, taking into account the gas temperature dependence of the reaction rates. It was observed that most of the species identified by FT-IR are predicted by the theoretical model as the most abundant in the discharge region. This result indicates that the chemical composition of the jet effluents can be controlled by only altering the design of the device, as the presence or absence of an insulator between the electrodes modifies significantly the gas temperature in the discharge region.

For the arc plasma jet the spectrum contains major contributions of NO and NO2 and minor contributions of N2O and HNO2. For the DBD jet, the absorbance of O3 and an influence of the residual H2O and CO2 content on the absorbance spectra were identified. Measured absorbance values below zero are due to a higher residual gas content during the acquisition of the background spectrum. In the case of H2O, this can visually mask an absorption of NO2 between 1540 and 1660 cm−1. Therefore, the reference functions for both NO2 and H2O were fitted mutually as a sum function in this wavenumber region to allow a distinction between both substances.
