This study presents the first known detection of fission products commonly found in post-detonation nuclear debris samples using solid sample introduction and a uniquely coupled gas chromatography inductively-coupled plasma time-of-flight mass spectrometer. Rare earth oxides were chemically altered to incorporate a ligand that enhances the volatility of the samples. These samples were injected (as solids) into the aforementioned instrument and detected for the first time. Repeatable results indicate the validity of the methodology, and this capability, when refined, will prove to be a valuable asset for rapid post-detonation nuclear forensic analysis.
本研究首次展示了使用固体进样和独特耦合的气相色谱-电感耦合等离子体飞行时间质谱仪,对爆后核碎片样品中常见裂变产物的检测。稀土氧化物经过化学改性,引入一种能提高样品挥发性的配体。这些样品(作为固体)被注入上述仪器并首次被检测到。可重复的结果表明了该方法的有效性,并且这种能力经过完善后,将被证明是爆后核法医快速分析的一项宝贵资产。
