How Ambient Conditions Can Compromise Density Measurements in

Dec 13, 2016 · Absolute pressure uses a vacuum as reference, while relative pressure uses ambient pressure as reference. By being referenced to a vacuum, absolute pressure eliminates any inaccuracies that can be caused by changes in ambient pressure. The actual gas pressure is accurately measured, leading to correctly calculated gas density.

Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density of 6.12 g/L at sea level conditions, considerably higher than the density of air. It is generally transported as a liquefied compressed gas. The concentration of SF 6 in Earthtroposphere reached 10 parts per trillion in year 2019, rising at 0.35 ppt/year. The increase over the prior 40 years was driven in large part by the expanding electric power sector, including fugi
