| 摘 要： | 标样与样品之间基体效应的差异是影响LA-ICP-MS分析结果准确度的重要因素,而元素的相对灵敏度因子(RSF)是基体效应的重要表征.本研究考察了17个玻璃标样中49种常见元素及10个电子探针天然硅酸盐矿物标样中10种主、微量元素RSF的差异,比较了以Ca,Al,Si为内标对基体效应的补偿作用及元素分馏效应的影响.结果表...

| Abstract: | Matrix effect between reference materials and samples plays an important role in the accuracy of analytical results by LA-ICP-MS.And elemental relative sensitivity factor(RSF) is an important characterization of matrix effect.We investigated the differences of RSFs of 49 common elements in 17 silicate glass reference materials and 10 major and minor elements in 10 natural silicate mineral reference materials of EMPA,compared different internal standard elements(Ca,Al,Si) to compensate for matrix effect and ... |
