用激光剥蚀电感耦合等离子体质谱(ICP-MS)法测定了刑侦案例中爆炸物硫磺的微量元素,克服了传统ICP-MS因样品前处理周期较长,延误公安司法部门破案时间这一缺点,本文用激光剥蚀样品采样的方法,快速准确的测定硫磺样品中的微量元素,缩短破案了时间,为公安司法部门提供有力的鉴定佐证。 Laser trace denudation inductively coupled plasma mass spectrometry (ICP-MS) was used to determine the trace elements of explosives sulfur in criminal investigation cases, which overcomes the shortcomings of traditional ICP-MS, such as long sample pretreatment period, In this paper, laser ablation sample sampling method, rapid and accurate determination of trace elements in sulfur samples, shorten the detection time, for the public security department to provide strong evidence to prove.
