The shipboard analysis of trace levels of sulfur hexafluoride, chlorofluorocarbon-11 and chlorofluorocarbon-12 in seawater
Abstract
Methods are described for the rapid (11 min) automated shipboard analysis of dissolved sulfur hexafluoride (SF 6) in small volume (∼200 cm 3) seawater samples. Estimated precision for the SF 6 measurements is ∼2% or 0.02 fmol kg -1 (whichever is greater). The method also allows for the simultaneous measurement of chlorofluorocarbon-11 (CFC11) and chlorofluorocarbon-12 (CFC12) on the same water sample, with significantly improved sensitivity over previous analytical methods.
