  • Ultra-Trace Analysis Technique for SF6 Using Gas

    2014-12-1Abstract. 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 greaterCited by: 7
