The aim of this project was to apply liquid phase electrochemical methodology to the gas phase. This was achieved by considering a flame, which is a weak plasma, as the electrolyte. All plasmas contain ions, electrons, excited species and neutral atoms and molecules. A dual burner was designed and built which had the capability to deliver two different gas streams to the burner head to produce one flame, with two discreet halves. Using the flame created with this burner as background electrolyte and aspirated solutions of metal salts added to the flame to alter the ion concentration; traditional two and three electrode electrochemistry experiments were applied to this system. This report discusses gas phase electrochemistry where ions in the gas phase comprise the electrode compartments and complete the electrical circuit. This thesis presents firstly a review of the literature pertaining to ions in flames, which includes natural flame ions and the ions created when metal salts are added to a flame. Electrochemical cells are also introduced and ions in solution are compared to ions in the gaseous phase. Diffusion potentials in a gaseous electrolyte will be introduced and discussed and the first evidence for there existence presented. Another important discovery will also be introduced and discussed namely the first redox potential measurements for gas phase ions.
