In this study 2k experimental designs were used for the optimization of an instrumental neutron activation analysis method for the determination of bromine, chlorine, magnesium, manganese, potassium, sodium and vanadium in biological matrix materials. Depending on radionuclide half-lives, 23 or 24 experimental designs were used with irradiation time, sample–detector distance, counting time and sample decay time as factors. Gamma ray spectrometer, comparator mass fraction and sample mass were kept constant. Optimized irradiation and measurement conditions were established based on the experimental design results that used z-scores as response on a reference material for the various elements and experimental conditions.

实验设计和 z 分数结果是优化仪器中子活化分析程序的有用工具

在本研究中，2k 实验设计用于优化仪器中子活化分析方法，用于测定生物基质材料中的溴、氯、镁、锰、钾、钠和钒。根据放射性核素半衰期，使用 23 或 24 种实验设计，将辐照时间、样品-探测器距离、计数时间和样品衰减时间作为因素。伽马射线光谱仪、比较器质量分数和样品质量保持恒定。优化的辐照和测量条件是基于实验设计结果建立的，该实验设计结果使用 z 分数作为对各种元素和实验条件的参考材料的响应。
