The lead content of 12 wine samples was measured by inductively coupled plasma-mass spectrometry using the methods of standard addition and isotopic dilution analysis. An additional wine sample was analysed by external calibration, standard addition and isotopic dilution analysis. The lead content of the wine samples was in the range 30-150 ng ml-1 and good agreement between the different techniques was observed. Analysis of lead isotope ratios revealed significant differences between Australian and European wines, reflecting the different isotopic composition of Australian lead.
采用标准加入法和同位素稀释分析法,通过电感耦合等离子体质谱法测定了12个葡萄酒样品中的铅含量。另外一个葡萄酒样品采用外标法、标准加入法和同位素稀释分析法进行分析。葡萄酒样品中的铅含量在30 - 150 ng ml-1范围内,不同技术之间观察到良好的一致性。铅同位素比率分析显示澳大利亚葡萄酒和欧洲葡萄酒之间存在显著差异,反映了澳大利亚铅的不同同位素组成。
