  • Analysis of Sulfur Hexafluoride in Air

    Sulfur hexafluoride dry air mole fractions are determined by gas chromatography with electron capture detection, relative to the WMO SF. 6. calibration scale. The WMO SF. 6. mole fraction scale is derived from gravimetrically-prepared primary standards (see TP_XXXX.doc). The procedures described here only pertain to SF. 6. analysis for which a

  • Sulphur Hexafluoride | Edinburgh Sensors | Gas Detection

    Sulphur Hexafluoride. NDIR sensors for measuring SF 6 leaks. Sulphur hexafluoride is an inorganic, colourless, odourless, non-flammable gas which is an excellent electrical insulator. It is an extremely potent greenhouse gas therefore it is important to minimise leaks of it to the environment. It absorbs strongly in the infrared, so NDIR sensors are ideally suited to detecting it at low ppm concentrations.

  • Sulfur hexafluoride - Wikipedia

    Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent 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 density of

However, methane is a greenhouse gas, extremely flammable, and can form explosive mixtures in air. Methane leaks can have devastating results, so detecting leaks is vital during natural gas extraction, transportation, and power generation.2-4 In the chemical industry production of syngas, methanol, acetic acid and other commodity chemicals depend on methane gas sensors to ensure that processes are operating safely and efficiently. Measuring atmospheric levels of methane is also becoming increasingly important for monitoring changing environmental conditions that may affect the environment and human health.2-4
