  • SF6 gas detector, Sulfur hexafluoride - GazDetect | Gas

    As sulfur hexafluoride can absolutely not be detected without proper equipment (odorless and colorless gas), only an SF6 detector can accurately measure concentrations of this asphyxiating gas and properly monitor SF6 gas hazards. Thus it is advised to use a fixed or portable sulfur hexafluoride detection device or complete system.

  • 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 ).
