✦ Synopsis

The permeability coefficients for a number of common gases passing through a F'TFE film used in an electrochemical sensor are reported. A comparison with published data, recalculated into similar units, shows a large spread of values found for the permeability of PTFE films, possibly due to the different thicknesses of the membranes used, or the varying processes used in the FIFE film manufacture, The permeability coefficients of gases through PTFE are shown to be almost invariant with molecular weight for the molecular weight range of 28-65.
