  • 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.

    Sulfur hexafluoride is primarily of anthropogenic origin but also occurs naturally in minerals, rocks, and volcanic and igneous fluids. Concentrations of SF 6 in air have rapidly increased from a steady state value of about 0.02-0.05 to over 7 parts per trillion during the past 40 years, and are expected to continue increasing.
