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

Experimental determination of noble gases and Sulfr hexafluoride, as tracers

The heavier noble gases (Kr and Xe) along with sf 6 show an earlier arrival time and a wider curve profile compared to He and Ne curves through the CO2 carrier gas stream. This shows that Kr and Xe could be substituted for Sulfr hexafluoride, a potent greenhouse gas, in tracer applications.Get price
