  • 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.
