Boron isotopic ratio measurement is very important in the nuclear industry because it is used as neutron poison (in the form of boric acid or a B4C pellet) and control rod material (B4C pellet) in nuclear power plants. Since 10B has a higher neutron absorption cross-section, enriched 10B is used in the nuclear industry and the extent of enrichment varies from 50–90 %. Therefore, it is essential to determine the 10B/11B ratio in boric acid and B4C. The prime purpose of the present study is to utilize LA-ICPMS for evaluating 10B/11B ratio both in solution (boric acid) and solid (B4C pellet) without any pre-treatment so that the difficulty in dissolution or powdering process of B4C (one of the hardest materials) can be avoided and the B4C pellet can be reused. The results obtained from LA-ICPMS for the B4C pellet are discussed and compared with the solution ICPMS, TIMS, and LIMS. The solutions of boric acid (natural abundance) and dissolved B4C (natural & ∼67 % enriched isotopic composition) were analyzed by LA-ICPMS and validated by liquid sampling ICPMS data.

使用 LA-ICPMS 测定硼酸和 B4C 中的 10B/11B

硼同位素比测量在核工业中非常重要，因为它被用作中子毒物（以硼酸或 B 的形式）4C 颗粒）和控制棒材料（B4C 颗粒）在核电站中。自从10B具有较高的中子吸收截面，富集10B用于核工业，浓缩程度从50%到90%不等。因此，有必要确定10乙/11硼酸和B中的B比例4C. 本研究的主要目的是利用 LA-ICPMS 进行评估10乙/11溶液（硼酸）和固体（B4C丸）未经任何预处理，导致B的溶解或制粉过程困难4C（最硬的材料之一）可以避免，B4C颗粒可以重复使用。 B 的 LA-ICPMS 获得的结果4讨论了 C 颗粒并与 ICPMS、TIMS 和 LIMS 解决方案进行了比较。硼酸（天然丰度）和溶解的 B 的溶液4C（天然和约 67% 富集同位素组成）通过 LA-ICPMS 进行分析，并通过液体采样 ICPMS 数据进行验证。
