We developed a novel apparatus for the measurement of the gas barrier properties of soft materials. The measurement principle is based on the use of a low temperature trap to transfer the permeated vapor from the sample space under atmospheric pressure to the mass spectrometer situated in an ultrahigh vacuum. We have demonstrated that the sensitivity, dynamic range and lead time for the measurement can be significantly improved from those previously reported. It was revealed that the diffusion time in a polymer film must be considered in the measurement of high barrier films.
