Sulfur hexafluoride | F6S - PubChem hexafluoride is a sulfur coordination entity consisting of six fluorine atoms attached to a central sulfur atom. It is the most potent greenhouse gas currently known, with a global warming potential of 23,900 times that of CO2 over a 100 year period (SF6 has an estimated lifetime in the atmosphere of between 800 and 3,000 years).

A ...
THE CARBON DIOXIDE LEAKAGE FROM CHAMBERS MEASURED …· In plant chamber studies, if Co2 leaking from a chamber is not quantified, it can lead to an overestimate of assimilation rates and an underestimate of respiration rates: consequently, it is critical that Co2 leakage be determined. Sulfur Hexafluoride (SF6) was introduced into the chambers as a tracer gas to estimate leakage rates. Chamber leakage in the chambers occurs via pressure ...
