An electrochemical cell was used to add trace quantities of oxygen to a gas stream. The viscosity of these gas mixtures was determined using an established method that measures the rate of change of viscosity with oxygen concentration. Viscosity data are reported for nitrogen/oxygen and helium/oxygen mixtures at very low oxygen concentrations. The data are compared with values for the viscosity of these gas mixtures, interpolated from results reported in the literature.
