    Abstract. Analysis procedures and instrumentation to measure low levels of sulfur hexafluoride in seawater are described. The minimum detectable level for a 500 mL sample is about 3×10 −17 mol/L. Concentrations from 1.5 to 300×10 −15 mol/L can be measured with approximately 2% precision. The procedure includes a concentration step employing a trap of Porapak‐Q© in a dry ice/2‐propanol bath.

    Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent man-made greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a de

    For the purposes of accurate sum-rule analysis, sulfur hexafluoride (SF 6) presents some problems. Although it has high (octahedral, O h) symmetry, it is a fairly large molecule containing a second-row atom, and hence involves 16 molecular orbitals. Electron escape from the central atom is impeded by a cage of electronegative atoms.
