  • Analysis of Sulfur Hexafluoride in Air

    The sulfur hexafluoride analysis system is described in Hall et al. (2007) and Hall et al. (2011). Briefly, gas samples are loaded into a fixed-volume, stainless steel sample loop by flushing the loop, and then injected onto a series of packed columns using a multi-port valve.
