Example of deconvolution results for the N₂-rich/CH₄ experiment. The black outlined bars show the normalized mass spectrum, while the colored sections indicate the model-fitted contribution of each identified species to its corresponding mass channel. Low intensity channels, shown as open black bars, represent background noise or masses not associated with stable products in the database. Species in the legend are ordered by molecular mass. The O₂ (m/z 32) and Ar (m/z 40) peaks are attributed to the RGA background, as they are present without additional gas injection and do not increase in the plasma-on spectrum relative to the plasma-off spectrum.
