Abstract
THE cathodic reduction of oxygen has been studied1 in connexion with corrosion and air-depolarized galvanic cells; but so far no use seems to have been made of this process in gas analysis. I have experimented with cathodes half-immersed in the electrolyte under nitrogen and hydrogen and, with suitably designed cells, have found that otherwise difficultly detectable traces of oxygen in the gas phase, such as 10−6 c.c./c.c, were capable of giving substantial and easily measurable currents.
