sulfur hexafluoride leak rate HAUG

The closure rate with C3F8 and SF6 reinjections was 3/4 (75%) and 1/5 (20%). Moreover, anatomical hole closure after resurgeries was better in Group 1 (4/5 eyes) than in Group 2 (0/4 eyes). The macular hole closure rate was similar with sulfurhexafluoride and perfluoropropane, irrespective of hole size, stage, or duration. However ...

  • Sulfur hexafluoride - Wikipedia

    Sulfur hexafluoride (SF 6) or sulphur hexafluoride (British spelling), 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.Chemical formula: SF₆

Accordingly, a leakage rate greater than 100% means that actions to reduce emissions within countries had the effect of increasing emissions
