A new method for measuring the permeability of synthetic membranes to water and ethanol has been developed. The technique involves using the membrane as a laser waveguide and making Raman scattering measurements from the guided laser beam. The measurements show that alcohol can be detected at low levels within damp cellulose acetate membranes. The results suggest that further exploration using waveguide and Raman measurements might lead to a better understanding of the mechanisms which affect the relative permeability of alcohol and water. 6 references, 4 figures, 1 table.
