  • Ventilation Measurements Using Sulfur Hexafluoride (SF6

    Mar 20, 2019 · Sulfur Hexafluoride, also known as SF6, is by far the most common tracer gas used for ventilation studies. The primary reason is that it is easy to detect at low concentrations—even in the parts per billion (ppb) or parts per trillion (ppt) range and has very low toxicity. The best instrument to detect SF6 is an infrared spectrophotometer.

  • Ventilation Testing – Determining Air Changes Per Hour (ACH

    Mar 20, 2019 · Another method is by using a tracer gas injected into the supply system—or space itself and measure the reduction in tracer gas over a fixed time. The most common gas to use is sulfur hexafluoride (SF 6 ) since it is relatively non-toxic (OSHA PEL is 1,000 ppm) and is not naturally present in the air so it is easy to detect.

  • 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 ).

  • Measurement of the diffusion coefficient of sulfur

    Abstract. Sulfur hexafluoride has been widely used in field studies and laboratory experiments to develop a relationship between gas transfer and wind speed. The interpretation of the data from such studies requires the diffusion coefficient of SF 6 ( DSF6 ), which has not previously been measured. In this study, DSF6 has been determined in pure water and in 35‰ NaCl over a temperature range of 5–25°C.
