  • Ultra-Trace Analysis Technique for sf6 gas 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.

    Accuracy of an instrument is a combination of both of the values. Instruments are rated as a percentage of reading with an added offset. The offset is added, with percentage of reading, because if the percentage of reading was used on a low value such as 1.0 the instrument would need to be very precise.
