  • 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 ).
