| 摘要: |
| 采用新型高灵敏度碰撞/反应技术CRI-ICP-MS,在海水稀释10倍后测定其中的铜、铅、锌、镉、铬、砷、硒7种痕量元素。实验中碰撞/反应界面自动切换,而且在一次分析过程中就可以完成所有目标元素的测量。方法检出限为0.024~0.095 ng/ml,加标回收率为84.2%~113.2%,所得标准物质分析结果与证书值基本一致。 |

| Abstract: |
| A new type of high sensitivity inductively coupled plasma mass spectrometry (ICP-MS) with collision reaction interface (CRI) technology was applied to determine Cu, Pb, Zn, Cd, Cr, As and Se in 10 times diluted seawater.During the experiment collision/reaction interface switches automatically, and a process of analysis can be completed all measurements of the target elements.The determination limits of the method are 0.024~0.095 ng/ml, and the spiked recoveries are 84.2%~113.2%.The analysis result of standard substance is consistent with the certificate. |
