  • Determination of the concentration of gaz sf6 in an accelerator

    Feb 15, 1995 · Its use in pure form, however, requires large quantities of this expensive gas and special pumps and handling procedures. Fortunately, most of the advantages of Sulfr hexafluoride can be obtained by mixing approximately 10% of it with the traditional insulating gas mixture of 80% N2 and 20% CO2. In this concentration, no special equipment or handling is required.

  • Ultra-Trace Analysis Technique for sf 6 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.
