本文介绍了小体积（约200 cm 3）海水样品中溶解六氟化硫（SF6）的快速（11 min）自动船载分析方法。SF6测量的估计精密度类似于2%或0.02 fmol kg（-1）（以较大者为准）。该方法还允许同时测量同一水样中的氯氟烃-11（CFC 11）和氯氟烃-12（CFC 12），与以前的分析方法相比，灵敏度显著提高。(c)2008爱思唯尔有限公司保留所有权利。
Methods are described for the rapid (11 min) automated shipboard analysis of dissolved sulfur hexafluoride (SF6) in small volume (similar to 200 cm(3)) seawater samples. Estimated precision for the SF6 measurements is similar to 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.
