08482 IUPAC Gold Book - glow electric discharge 10.1351/goldbook.08482 08482 current synonym: glow discharge 1 Electric discharge in gas at low pressure (\(\pu{100}\) to \(\pu{1000 Pa}\)). In atomic emission spectroscopy argon is used as the inert working gas that generates the plasma. In the prevailing electrical field the produced ions are accelerated towards the cathode, resulting in a continuous bombardment of the sample surface.
