地质样品Sr同位素激光原位等离子体质谱(LA-MC-ICP-MS)测定被引量：14: 2009年; Sr同位素在研究岩浆演化及其源区具有重要的示踪作用。MC-ICP-MS的出现为具有高Sr含量地质样品的激光原位Sr同位素测定变成了现实。本文利用Netpune MC-ICP-MS和193nm准分子激光联机,通过滨珊瑚、斜长石、磷灰石和钙钛矿等系列实验,建立了激光原位Sr同位素测定方法。实验结果表明,激光Sr同位素测定中Kr、Rb和稀土元素二价离子的干扰能够有效扣除,而钙聚合物的干扰在Neptune型MC-ICP-MS并不显著。不同激光参数的实验表明,大激光束斑产生更高信号强度,因而Sr同位素精度更高,同一激光束斑大小,激光脉冲频率对Sr同位素精度无明显影响。; 杨岳衡吴福元谢烈文杨进辉张艳斌; 关键词：地质样品激光原位等离子体质谱 PORITES

地质样品Nd同位素激光原位等离子体质谱(LA-MC-ICPMS)测定被引量：18: 2008年; 利用配有193nm激光的Neptune多接收等离子体质谱仪(MC-ICPMS),采用最新发表的Sm同位素丰度和本研究中测定的Sm和Nd之间的质量歧视关系,对磷灰石、榍石、独居石和钙钛矿等天然矿物进行了一系列微区原位Nd同位素测定.结果表明,大量Ce的存在不会影响Nd同位素的精确与准确测定,在Sm/Nd<1(147Sm/144Nd<0.6)范围内,建立的方法可以准确获得足够Nd含量地质样品的Nd同位素组成.结合其微量元素和U-Pb年龄,激光Nd同位素资料可为精细地质作用过程的探讨提供重要信息.; 杨岳衡孙金凤谢烈文范宏瑞吴福元; 关键词：ND同位素榍石
