Presentation Summary

  • An alternative highly sensitive method for measuring water vapor transmission rates (WVTR) of ultra-barrier films is presented.
  • Detection limit in the 10-6 g m-2 d-1 regime
  • Several advantages: no interaction with the sensor material, no side diffusion (negligible), assessment of steady-state and time lag easier than for established methods.
