It has been demonstrated that the addition of N2, CO, Ne, Ar, Kr, Xe, CO2, and CF4 to a H2-air diffusion flame containing He and traces of CH4 enhances the level of ion formation. This enhancement is proportional to the concentration of both CH4 and the diluent gas, consistent with the proposition that the diluent gas participates in the ion formation process.

Ion formation from traces of C2N2 in a H2 + He-in-air diffusion flame is enhanced by the presence of traces of Ne, Ar, Kr, Xe, N2, CO, CO2 and CF4. The enhancement is proportional to the concentration of both C2N2 and the diluent gas and the relative efficiencies are identical to those observed when hydrocarbons are the source of ionization. The observations are consistent with the involvement of the diluent in ion formation, parallel to the hydrocarbon system.
