目前,地气样品分析方法主要有质子激发X荧光分析(PIXE)(L.Malmqvist et al.,1999)、中子活化分析(INAA)(童纯菡等,1992)、原子吸收光谱法(AAS)(刘应汉等,1995)、电感耦合等离子体质谱法(ICP-MS)(刘应汉等,2003)等。但是,由于地气样品中元素含量非常低,需要高精度、高准确度和高灵敏度的仪器分析检测。而美国Perkin-Elmer公司制造的电感耦合等离子体 At present, the methods for the analysis of groundwater samples include PIXE (LALMqvist et al., 1999), INAA (TORONTO et al., 1992), AAS ( Liu Yinghan et al., 1995), inductively coupled plasma mass spectrometry (ICP-MS) (Liu Yinghan et al., 2003). However, due to the very low content of elements in ground gas samples, instrumental analysis testing with high accuracy, high accuracy and high sensitivity is required.
