sulfur hexafluoride Calibration

Sulfur hexafluoride (sf6-gas) is an inorganic, colorless, odorless, non-flammable, non-toxic but extremely potent greenhouse gas, and an excellent electrical insulator. sf6-gas has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. Typical for a nonpolar gas, it is poorly soluble in water but quite
