[Measurement of binary diffusion coefficients of oxygen and another gas (author's transl)]

Diffusion coefficients between oxygen and seven other gases (air, N2, He, Ne, Ar, CO2, SF6) have been measured using a set-up derived from Loschmidt's tube. Measurements have been made continously with an electrochemical cell sensitive to oxygen. The causes of errors are reviewed. The influence of gravity is discussed.
