| 摘 要： | 建立了微波消解-ICP-MS测定人体血浆中30种痕量元素的方法。血浆样品经过微波消解，在优化ICP-MS仪器工作参数后，以双内标铑(Rh)和铼(Re)进行校正。测定的结果表明，30种痕量元素的检出限为0.01～0.68 ng·mL-1,回收率为85%～119%，相对标准偏差(RSD)为1.7%～10.2%。用该方法对国家标准物质牛血清成分(GBW 09131)进行测定，其元素浓度均在标准值范围内。因此微波消解-ICP-MS方法快速、简便、准确，适于人血浆等生物样品中多种痕量元素的测定。 |

| Abstract: | A method for determining 30 trace elements in human plasma was developed by using microwave digestion-ICP-MS. Under the optimized conditions the samples were analyzed by ICP-MS after microwave digestion. The double internal standard elements Rh and Re were used to compensate for matrix suppression effect and sensitivity drift. The analytical results showed that the detection limits of the 30 trace elements were in the range of 0.01-0.68 ng·mL-1. The recovery rates of the studied elements were from 85% to 119%. The relative standard deviations (RSD) of the method were in the range of 1.7%-10.2%. The national standard reference material GBW 09131 was analyzed by the described method and the measured element values accorded with the standard values. It is indicated that the method is rapid, simple and accurate for determining trace elements in human plasma. |
