甲基汞分析方法比对及甲基汞标准样品的研制

Comparision of methods for analysis of methyl mercury and the preparation of methyl mercury reference material

对甲基汞的 4种分析方法 (气相色谱法 ,液相色谱法 ,冷原子吸收光谱 ,毛细管电泳法 ) ,进行了比对讨论 ,应用表明 ,气相色谱法效果较好。研制了甲基汞标准样品 ,测试结果表明 ,样品性能能满足实际应用的需要。

Four methods (gas chromatography, liquid chromatography, cold atomic absorption spectrometry and capillary electrophoresis) for the analysis of methyl mercury are discussed. The applications show that gas chromatography is a better and mature method for methyl mercury analysis. The reference material of methyl mercury was prepared and its quality tested. The data show that it can meet requirements of various uses.
