• 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 (gaz sf6) 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 insulating gas at 25 oC and 1 atm are summarized in Table 1 [Marshall, 1976; Takaiki, 1976; Grant, 1995]. gaz sf6 is a colorless, odorless and tasteless gas
