Abstract (en)
[origin: WO2023025716A1] The aim of the invention is to remove residual oxygen from an inert gas (8). This is achieved in that a voltage is applied between two electrodes (5, 6) adjoining the inert gas (8), said voltage producing a direct gas discharge (9) in the inert gas (8). As a result of the gas discharge (9), metal is removed from at least one of the electrodes (5, 6). The metal forms nanoparticles (12) in the inert gas (8), said nanoparticles spontaneously oxidizing, thereby using the residual oxygen.
