  • 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

  • 10 Tips for Getting the Most Out of an Optical Gas Imaging

    Understand the application and the need. Different applications require different cameras. In other words: one camera may not see all the gases, so you need to understand which type of gas you are dealing with. Take the environment into account. The success of OGI depends on environmental conditions. The greater the background energy differential, the easier the camera will be able to visualize the gas leak and pinpoint its source. Remember: OGI is qualitative, not quantitative.* Due to the environmental variants and the background energy differential and variations, an OGI camera alone cannot determine the specific type or amount of gas escaping through a leak. Use all the features of your OGI camera. Learn how each feature of the OGI camera works - such as automatic GPS tagging or image enhancements - and use them to your advantage.
