摘要:
爆炸物的种类繁多，对安防检测工作造成较大困难，急需选择一种可以快速定性分析多种爆炸物的方法。针对16种常见爆炸物样品，选择电喷雾离子(ESI)源结合高分辨轨道离子阱进行测定。结果表明：实验用16种爆炸物中，有11种能够很好地检测出分子离子峰，其余5种可以检测出易于辨识的碎片离子峰；并且16种爆炸物的混合物质可以被很好地检测。ESI源是一种软电离方式，结合高分辨轨道离子阱能够准确对多种爆炸物进行检测，适合用于安防检测领域。
Abstract:
Diversity has caused great difficulties in the security detection of explosives. Therefore, it is important to choose an identical analytical method for multiple explosives detection. A high resolution orbitrap mass spectrometry with electron spray ionization (ESI) source was utilized for identifying sixteen kinds of commonly used explosives. The results show that the molecular ionic peaks can be identified for eleven explosives, while fragment peaks can easily be detected for the other five explosives. Thus, the mixture of the sixteen explosives can be successfully filtered. Electron spray ionization is a kind of soft ionization way, it is useful to detect several explosives with high resolution orbitrap and suitable for security detection.
