摘要
应用实时直接分析-高分辨飞行时间质谱(DART-HR-TOFMS)对硝胺类有机炸药黑索金(RDX)及其爆炸残留物进行精确质量质谱分析,借助MassWorks质谱解析软件对质谱数据进行了噪音过滤及峰形校正处理,获得了炸药准确的同位素分布模式,然后通过实际同位素分布模式的校正峰形与理论峰形匹配的谱图准确度对待选的分子式进行排序,实现了RDX的准确识别和鉴定。
DART-HR-TOFMS was used for accurate mass MS analysis of organic explosives RDX and its explosive remnants.Accurate isotopic distribution patterns of the explosives were obtained by using the analysis software of MassWorks for noise filtering and peak shape correction of the mass spectrometry data.The spectral accuracy obtained by matching the theoretical peak shape and the corrected peak shape of the actual isotope distribution patterns was used for reordering the selected formulas to achieve accurate identification and characterization of RDX explosives.
