• 摘要：用测汞仪和气相色谱联用测定了CH₃HgCl、C₂H₂HgCl和（C₂H₅）₂Hg等不同形态的有机汞化合物,并且分离测定了三种烷基汞混合物。CH₃HgCl的最低检测量为10^-10g。另外,在没有富集情况下测定了人工混合样和海水加入的回收率。

• Abstract：GC in combination with a mercury analyzer system (MAS) has been used to determine organic mercury compounds in different species, such as CH₃HgCl, C₂H₂HgCl and (C₂H₅）₂Hg and also separate as well as determine mixtures of these three alkyl mercury compounds. The detection limit for CH₃HgCl is found 10^-10g. Recovery ratio of mercury from both artificially mixed samples and samples spiked with sea water have been determined.
