  • 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.

    Because high voltages (minus 1.2 MV) are applied to these pieces of equipment, they are stored in tanks filled with SF 6 (sulfur hexafluoride) gas to prevent electrical discharge. In addition, the high-voltage power supply is installed at a location separated from the main unit of the electron microscope to reduce the influence of the various types of noise it emits; the supply is connected to the main unit by a high-voltage cable.
