The selectivity of the products at different O$_2$:C$_4$H$_{10}$ ratios under an applied voltage of 650 V.
    Conditions: 500 sccm He, 0.5 sccm C$_4$H$_{10}$, O$_2$:C$_4$H$_{10}$ = 6.5; 13.25; 20; 26.75, corresponding to O$_2$ flow rates of 3.25, 6.625, 10, and 13.375 sccm, respectively. The products are arranged from left to right as CO (blue), CO$_2$ (green), CH$_4$ (red), and C$_2$H$_2$ (purple), unassigned species (gray). The unassigned species may originate from water or carbonaceous species on the dielectric and cannot be specifically identified.
