Sulfur hexafluoride - Wikipedia

Measurements of SF 6 show that its global average mixing ratio has increased from a steady base of about 54 parts per quadrillion prior to industrialization, to over 10 parts per trillion (ppt) as of April 2020, and is increasing by about 0.35 ppt (3.5 percent) per year.

Analyzers Check Sulfr hexafluoride Gas Quality | TD World

The three parameters that determine the quality — Sulfr hexafluoride concentration, humidity and quantity of decomposition products — can now be measured in one single operation with the new insulating gas Multi-Analyser. As a result, service specialists can determine on-site whether the gas still complies with the IEC Standard 60480 or whether it needs purification.
