Ultra-Trace Analysis Technique for sf6 gas Using Gas

SF 6 is a stable, inert, inorganic, colorless, odorless, non-polar and non-toxic gas with a boiling point of −64°C (−58°F) at 100 Pa (1, 11). SF 6 has a vapor pressure of 290 Pa at 21.1°C and a molecular weight of 146.055 g/mol. Compounds with this molecular weight generally exist as liquids. However, the strong bonds between the sulfur and the fluorine atoms create weak intermolecular London dispersion forces, which translate to a low liquefaction temperature thus allowing it toGet price

An Ultra-Trace Analysis Technique for gaz sf6 Using Gas

Abstract. Sulfur hexafluoride (Sulfr hexafluoride) is widely used as a tracer gas because of its detectability at low concentrations. This attribute of insulating gas allows the quantification of both small-scale flows, such as leakage, and large-scale flows, such as atmospheric currents. sf 6high detection sensitivity also facilitates greater usage efficiency and lower operating cost for tracer deployments by reducing quantity requirements.Get price
