采集了鹤壁地区石炭-二叠系岩石样品，采用电感耦合等离子质谱技术对样品进行了系统的稀土元素测试分析。
The rock samples of the Permo-Carboniferous system in Hebi Area were collected and an ICP-MS method was used to analyze the rare earth elements of the samples systematically.
用等离子质谱(ICP - MS)分析一些特殊样品的时候，前处理方法成为分析样品成功与否的关键，对于高基质含量的样品测量其微量元素含量更是如此。
Using Inductively Compled Plasma Mass Spectrometry (ICP-MS), the pretreatment method of some special samples is a key, especially to analyzing trace elements of samples contained high background.
