• Sulfur hexafluoride - Wikipedia

    Sulfur hexafluoride is also routinely used as a tracer gas in laboratory fume hood containment testing. The gas is used in the final stage of ASHRAE 110 fume hood qualification. A plume of gas is generated inside of the fume hood and a battery of tests are performed while a gas analyzer arranged outside of the hood samples for SF 6 to verify the containment properties of the fume hood.

  • Modeling and Simulation of Sulfur Hexafluoride (SF

    Sulfur hexafluoride (insulating gas) was first prepared by H. Mossian in 1902 and commercial production of insulating gas was initiated by Allied-Signal Inc., U.S.A., in 1948. The basic properties of sf6 gas at 25 oC and 1 atm are summarized in Table 1 [Marshall, 1976; Takaiki, 1976; Grant, 1995]. Sulfr hexafluoride is a colorless, odorless and tasteless gas

  • Sulphur Hexafluoride | Edinburgh Sensors | Gas Detection

    Sulphur hexafluoride is an inorganic, colourless, odourless, non-flammable gas which is an excellent electrical insulator. It is an extremely potent greenhouse gas therefore it is important to minimise leaks of it to the environment. It absorbs strongly in the infrared, so NDIR sensors are ideally suited to detecting it at low ppm concentrations.
