  • Sulfur hexafluoride | F6S - PubChem

    Sulfur hexafluoride is a sulfur coordination entity consisting of six fluorine atoms attached to a central sulfur atom. It is the most potent greenhouse gas currently known, with a global warming potential of 23,900 times that of CO2 over a 100 year period (SF6 has an estimated lifetime in the atmosphere of between 800 and 3,000 years).

  • Ultra-Trace Analysis Technique for SF6 Using Gas

    Abstract. Sulfur hexafluoride (SF 6) is widely used as a tracer gas because of its detectability at low concentrations.This attribute of SF 6 allows the quantification of both small-scale flows, such as leakage, and large-scale flows, such as atmospheric currents. SF 6 s high detection sensitivity also facilitates greater usage efficiency and lower operating cost for tracer deployments by

  • Sulfur Hexafluoride and Potassium Bromide as Groundwater

    Abstract Sulfur hexafluoride (SF 6) is an established tracer for use in managed aquifer recharge projects. SF 6 exsolves from groundwater when it encounters trapped air according to Henrys law. This results in its retardation relative to groundwater flow, which can help determine porous media saturation and flow dynamics.
