Sulfur Hexafluoride Handling System maintenance. Sulfur hexafluoride (sf6 gas) is inert (won't mix with anything) and non-toxic.It can do some surprising things even in small quantities. Except, don't try these at home for two reasons: (1) you have to be trained in its correct use and handling and, (2) sf6-gas-gas is quite expensive. [email protected]

    It contains six atoms of fluorine bound to a single sulfur atom, hence the name Sulfur Hexafluoride. It is an inorganic fluorinated inert gas with potential imaging-based diagnostic activity. The gas on inhalation is spread all over the lungs. Upon subsequent imaging by ultrasound technology, lung vasculature can be imaged. Thus, pulmonary perfusion assessment becomes easy.

  • Ultra-Trace Analysis Technique for SF6 Using Gas

    Sulfur hexafluoride (SF 6) is widely used as a tracer gas because of its detectability at low concentrations. This attribute of SF 6 allows the quantification of both small-scale flows, such as leakage, and large-scale flows, such as atmospheric currents. SF 6 s high detection sensitivity also facilitates greater usage efficiency and lower operating cost for tracer deployments by reducing quantity requirements.
