  • 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.File Size: 238KB

  • Analysis of sulfur hexafluoride in seawater - Wanninkhof

    Analysis procedures and instrumentation to measure low levels of sulfur hexafluoride in seawater are described. The minimum detectable level for a 500 mL sample is about 3×10 −17 mol/L. Concentrations from 1.5 to 300×10 −15 mol/L can be measured with approximately 2% precision. The procedure includes aCited by: 104

  • Ultra-Trace Analysis Technique for SF6 Using Gas

    2014-12-1Abstract. Sulfur hexafluoride (SF 6) is widely used as a tracer gas because of its detectability at low concentrations.This attribute of SF 6 allows the quantification of both small-scale flows, such as leakage, and large-scale flows, such as atmospheric currents. SF 6 s high detection sensitivity also facilitates greaterCited by: 7

  • USGS Groundwater Dating Lab

    Sulfur hexafluoride is primarily of anthropogenic origin but also occurs naturally in minerals, rocks, and volcanic and igneous fluids. Concentrations of SF 6 in air have rapidly increased from a steady state value of about 0.02-0.05 to over 7 parts per trillion during the past 40 years, and are expected to continue increasing.

  • Simultaneous Analysis of Noble Gases, Sulfur

    2019-12-12We developed an analytical method for the simultaneous measurement of dissolved He, Ne, Ar, Kr, Xe, SF6, N2, and O2 concentrations in a single water sample. The gases are extracted from the water using a head space technique and are transferred into a vacuum system for purification and separation into differentCited by: 6
