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
