  • Sulfur hexafluoride detection by Radar resonance enhanced

    In this study, we have demonstrated the stand-off detection of sulfur hexafluoride by the Radar resonance multi-photon ionization process. In order to obtain a well defined spectral signature, the sulfur hexafluoride molecules are first dissociated by a focused pulsed Nd:YAG laser to sulfur difluoride molecules, which are then ionized by a pulsed, frequency tunable, narrow linewidth laser

  • Sulfur Hexafluoride and Potassium Bromide as Groundwater

    Sulfur hexafluoride (SF 6) is an established tracer for use in managed aquifer recharge projects. SF 6 exsolves from groundwater when it encounters trapped air according to Henrylaw. This results in its retardation relative to groundwater flow, which can help determine porous media saturation and flow dynamics.

  • Sulphur Hexafluoride | Edinburgh Sensors | Gas Detection

    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.
