描述了通过 ICP-MS 测定岩石和矿物中 Ba 和稀土元素的分析程序。 The yield of mono-oxide and hydroxide ions of Ba and rare earth elements, and chloride ions of Ba has been determined. 已编写 Microsoft Excel 电子表格模板来计算所有可能的分析物种类（M+、MO+、MOH+ 和 MCl+）的预期峰强度，作为质量数的函数。 估计不同分析物同位素的干扰程度，并给出元素的干扰当量浓度，对于这些元素，没有不受干扰的同位素。 该方法应用于四种地理参考样本AC-E、GSP-1、G-2和AGV-1的分析；与推荐的参考值相比，大多数元素的分析精度优于 +/- 10%。
The analytical procedure for the determination of Ba and rare earth elements in rocks and minerals by ICP-MS is described. The yield of mono-oxide and hydroxide ions of Ba and rare earth elements, and chloride ions of Ba has been determined. A Microsoft Excel spreadsheet template has been written to calculate the expected peak intensities for all possible analyte species (M+, MO+, MOH+ and MCl+) as a function of the mass number. The degree of interferences of different analyte isotopes is estimated and interferent equivalent concentrations are given for elements, for which no isotope free from interferences is available. The method is applied to the analysis of the four Geo-Reference samples AC-E, GSP-1, G-2 and AGV-1; the analytical accuracy is better than +/- 10% for most of the elements when compared with recommended reference values.
