Often, gas standards in cylinder mixtures are very reactive and instable, especially at low concentrations. Permeation tubes are ideal devices in generation of calibration gas standard for:

  • air quality analyzers
  • gas analyzers – FTIR
  • gas chromatograph
  • GC-MS
  • Ion Mobility Spectrometer
  • sniffers
  • measurement of methane emission from ruminant livestock using a SF6 (sulfur hexafluoride) tracer technique
  • Electronic nose

With permeation devices is possible to modify the mixture components by removing and/or adding a single tube into a permeation chamber. GC-MS calibration are also available for deuterate substances.

  • Permeation devices are used for:
  • Petrochemical plants and Refinery
  • Semiconductor industry (trace moisture standard)
  • Gas sensor development
  • Test with controlled atmosphere
  • Catalyst test with synthetic gas
  • Test on Odours Monitor
