In gas permeation, the transmission rates of thin films can be determined.
  •  Characterization of barrier properties and permeation parameters of thin films (foils and gels)
  • Determination of transmission rates: WVTR (water vapor) following ASTM F-1249, HeTR (helium), OTR (oxygen from air), also of other gases (e.g. H2S).
  • Different temperatures and gas humidities are achievable
  • Determination of transmission rates: WVTR (water vapor) following ASTM F-1249 and DIN EN ISO 15106-3
