Sep 01, 2016 · Sulphur hexafluoride (SF 6) is a non-toxic, odourless gas with unique electrical properties. For over 50 years, it has been used in high-voltage gas-insulated switchgear (GIS), where its excellent dielectric and arc-quenching properties make it an ideal insulating gas for medium- and high-voltage equipment. However, when the gas decomposes, it forms decomposition products that are toxic to maintenance personnel and harmful to equipment.

sf6 gas Lab: Groundwater and Soil Air | Lamont-Doherty Earth

SF 6 is separated from other gases by a molecular sieve 5A column at room temperature. Currently, water samples are collected using glass syringes. After equilibration of the gases dissolved in the water with a head space in the syringe, the gas samples are injected directly into the GC system via the sample loop method. With this method, the minimum and maximum concentration typically measured are 8 fM and 8E4 fM, respectively (1 fM = 1 femtomoles = 10 E-15 mol/L).
