A membrane wedge interferometer was designed for obtaining steady state mass transfer data on liquid‐membrane‐liquid systems. Procedures were developed for analyzing the diffusive transfer process, and experiments were conducted on the ethyl alcohol‐water‐cellophane membrane system to obtain the type of data needed for elucidating mechanisms of membrane transport. The proposed technique provides an accurate method of studying membrane transport without the troublesome complications which characterize other methods.
