| 摘 要： | 建立了激光剥蚀等离子体质谱法直接测定Li2B4O7熔融玻璃中微量元素的分析方法。详细讨论了内标元素的选择及Li2B4O7熔融玻璃的均一性、背景空白对分析测定的影响。以Li2B4O7熔融玻璃中低同位素丰度的6Li作内标，水系沉积物国家标准参考物质熔融玻璃建立多元素标准校正曲线，用于标准参考物质及水系沉积物定值样品的分析，测定值与标准值或溶液雾化等离子体质谱结果比较，具有较好的一致性。 |

| Abstract: | A direct determination of trace elements in stream sediment samples by laser ablation-inductively coupled plasma mass spectrometry (LA-ICPMS) with Li2B4O7 fusion glass sample preparation was developed.The low abundance isotope of lithium(6Li) in the flux was selected as internal standard.The effects of homogenization of fusion glasses and the flux blank on the analytical signals were discussed.Multi-standard calibration was used with fusion stream sediment reference glasses to quantify the trace elements in sediment samples.The proposed method has been applied to the direct analysis of trace elements in National Standard Reference Materials and stream sediment samples.The analytical results are in good agreement with certified values and those from conventional ICPMS determinations. |
| Keywords: | Li2B4O7 fused glass laser ablation-inductively coupled plasma mass spectrometry(LA-ICPMS) trace element National Standard Reference stream sediment sample |
