  • Aircraft Release of Sulfur Hexafluoride as an Atmospheric Tracer

    In this mode the liquid is forced into the delivery system by the vapor pressure above the liquid in the cylinder, 320 psig at 70°F (2.2 M Pa at 21°C). An alternative approach, adopted here, is to invert the cylinder and withdraw the liquid directly from the cylinder valve, again making use of gas pressure within the cylinder to expel the liquid.
