sulfur hexafluoride Analysis for Maintenance

Abstract Sulfur hexafluoride (sf6 gas) 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.
