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0．024-0．095ng／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。
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.
