A rapid method for the measurement of sulfur hexafluoride

Abstract. A rapid headspace method for the simultaneous laboratory determination of intentionally introduced hydrologic tracers, sulfur hexafluoride (SF 6 ), trifluoromethyl sulfur pentafluoride (SF 5 CF 3 ), Halon 1211 (CF 2 ClBr), and other halocarbons in water and gases is described. The high sensitivity of the procedure allows for introduction of minimal tracer mass (a few grams) into hydrologic systems with a large dynamic range of analytical detection (dilutions to 1:10 8 ).Get price

Sulfur hexafluoride - Wikipedia

Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density ofGet price

Sulfur Hexafluoride - an overview | ScienceDirect Topics

Sulfur hexafluoride (SF 6) has been used as an intraocular tamponading agent and can persist in the eye for up to 3 months after surgery, during which time further anesthesia using nitrous oxide will cause the intraocular gas bubble to expand, increasing intraocular pressure, as has been shown in cats [10], modelled in silico [11], and reported in patients [12–16]. It has been suggested that all such patients should have warning bracelets detailing the presence of intraocular gas and thatGet price

Sulfur Hexafluoride - an overview | ScienceDirect Topics

Sulfur hexafluoride (SF 6) is produced largely for use as an insulating gas in electrical distribution equipment. Its concentrations have been increasing linearly since measurements began in the late 1970s, and a significant north-south gradient consistent with its predominantly northern hemisphere source is observed ( Figure 4 ).Get price
