| Abstract: | The determination of impurities in high purity aluminium was measured by ICP-MS.The uncertainty for determination of impurities were analysed and evaluated using a mathematical model.The impacts of major source of uncertainty were discussed,such as sample pretreatment,standard solution,standard curve and measurement repeatability.The standard uncertainty of components and the composed uncertainty were analyzed and calculated.The final results were expressed more objectively. |
