    The loss rate of sulphur hexafluoride is generally about 0.5 percent by volume of SF 6 per year. These leaks must be eliminated immediately, since sulphur hexafluoride is extremely harmful to the environment. Depending on the operating duration SF 6 must therefore be checked and replaced regularly.

  • 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 high detection sensitivity also facilitates greater usage efficiency and lower operating cost for tracer deployments by reducing quantity requirements.
