| 摘 要： | 建立了同位素稀释等离子体质谱法（ID—ICP—MS）测定地质样品中痕量硼的方法。采用减压排空色谱柱分离样品中的大量基体，以减少基体效应的影响，具有试剂用量少、分离速度快、效果好等特点。对两个标准物质GSD-4和GSD-8的测定结果表明，其与参考值吻合得较好，相对偏差均小于6％。3个不同样品的测定结果表明，该方法具有较好的准确度和精密度。 |

| Abstract: | A method for the determination of trace boron in various samples by isotope dilution-inductively coupled plasma mass spectrometry(ID-ICP-MS) was presented.Experimental results showed that by using a decompressed chromatographic column,the sample matrices could be separated rapidly and efficiently.The analytical results of boron in GSD4 and GSD-8 standards agreed quite well with the reference values.The relative error was 1.2%-5.8%.The relative error of the analytical results of boron in three samples was 0.9%-4.8%. |
