摘要
将电感耦合等离子体质谱法(ICP-MS)与电感耦合等离子体原子发射光谱法(ICP-AES)联合使用,结合2种仪器的优势,建立仪器分析和数据处理方法。采用建立的联合方法实测了辐照后镍金属制备63Niβ放射源工艺监控样品的63Ni活度浓度,并将所测结果与液体闪烁计数器法(LSC)测量结果进行对比。结果表明,2种方法所测结果的最大偏差为5.1%,测量结果的不确定度为4.4%(k=2),证明该联合测量方法准确可行。
Inductively coupled plasma mass spectrometry(ICP-MS) and inductively coupled plasma atomic emission spectrometry(ICP-AES) were used together to establish the methods of instrumental analysis and data processing. The activity concentration of 63Ni in the process of preparation of 63Ni β radioactive source from nickel metal after irradiation was measured by the established method in this paper. The measuring results were compared with that from the Liquid scintillation counting(LSC) method. The maximum relative deviation between two methods is 5.1%, and the uncertainty of the measurement results is 4.4%(k=2), which is proved that the method is accurate and feasible.
