  • Dating young groundwater with sulfur hexafluoride: Natural

    Sulfur hexafluoride (SF 6) is primarily of anthropogenic origin but also occurs naturally.The troposphere concentration of SF 6 has increased from a steady state value of 0.054±0.009 to more than 4 parts per trillion volume during the past 40 years. An analytical procedure was developed for measuring concentrations of SF 6 to less than 0.01 fmol/L in water.

  • 5 Differences Between Air-Insulated Substations and Gas

    Sulfur hexafluoride is five times heavier than air and offers excellent extinction behavior. Another significant construction-based difference between the two switchyards is that a metal-clad AIS uses three-position draw-out circuit breakers (on, off and test).

  • 3.3: Masses of Atoms and Molecules - Chemistry LibreTexts

    Oct 19, 2020Sulfur hexafluoride is used as a model compound for sarin. SF 6 (a molecular model of which is shown in part (b) in the accompanying figure) has a similar molecular mass (about 146 u) as sarin (about 140 u), so it has similar physical properties in the vapor phase. Sulfur hexafluoride is also very easy to accurately detect, even at low levels
