Abstract
Aspects of accuracy and precision of the determination of As and Sb in biological materials, using neutron activation with hydride generation, are discussed. It proves necessary to perform a yield determination for each sample. Both radiotracers and reactivation have been applied, and their practical use for yield correction is discussed. Results for several RMs are presented.
摘要
讨论了采用氢化物发生中子活化法测定生物材料中砷和锑的准确度和精密度方面的问题。事实证明有必要对每个样品进行产率测定。已应用放射性示踪剂和再活化方法，并讨论了它们在产率校正中的实际应用。给出了几个标准物质的结果。
