  • Analysis of sulfur hexafluoride in seawater - Wanninkhof

    Abstract. 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 a concentration step employing a trap of Porapak‐Q© in a dry ice/2‐propanol bath.
