摘要/Abstract

以爆炸条件下溶菌酶的反应产物为研究对象，运用基质辅助激光解吸-飞行时间质谱的方法研究其反应产物与不同炸药的反应特征性. 结果显示，雷管的使用不会对溶菌酶有影响，而在有爆炸物爆炸的条件下，除了正常溶菌酶酶解多肽信号外，一些[MH+17]⁺，[MH+18]⁺，[MH+28]⁺，[MH+32]⁺和[MH+44]⁺的加合峰信号也能被检测到. 这可能是在炸药爆炸过程中产生的一些活性小分子（如NH₃，H₂O，CO/N₂，O₂，CO₂）与溶菌酶发生反应得到的反应产物. 不同炸药生成的活性小分子能够分别与溶菌酶的某些反应位点反应生成特征性的反应产物，有利于这些炸药的分析与检测.

Identification and determination of explosives and explosive residues were a subject of continuing strong interest in analytical chemistry and forensic science. In this paper, the reaction products of lysozyme under the explosion condition were analyzed by a MALDI-TOFMS (Matrix-assisted laser desorption ionization time-of-flight mass spectrometry) method. There was no difference in the tryptic digest between the normal lysozyme and the reaction products generated by detonator, while some adduct peaks such as [MH+17]⁺, [MH+18]⁺, [MH+28]⁺, [MH+32]⁺, and [MH+44]⁺ were discovered in the explosives. This may be attributed to the reaction between the lysozyme and the active small molecule gases such as NH₃, H₂O, CO/N₂, O₂, CO₂, which were generated during the explosion. Characteristic peaks which were produced by lysozyme and the active small molecule gases from different explosives can be used to discriminate the six explosives. For example, H₂O molecules which were generated during the exploration by tri-nitrotoluene (TNT) can specifically react with VFGRCELAAAMKRHGLDNYR (m/z 2307) to produce a characteristic peak at m/z 2325 (2307+18). Also, H₂O molecules which were generated by hexahydro-1,3,5-trinitroazine (RDX) can completely react with IVSDGNGMNAWVAWRNRCK (m/z 2177) to produce a characteristic peak at m/z (2177+18). Characteristic peak at m/z 1301 was produced by GYSLGNWVCAAK (m/z 1269) and O₂ molecules for the identification of pentaerythritol tetranitrate (PETN). While for black powder, O₂and H₂O can both react with IVSDGNGMNAWVAWR (m/z 1676) to produce product ions peaks at m/z 1694 and 1708. However, only the O₂ molecules can react with IVSDGNGMNAWVAWR for pyrotechnic composition. As for ammon explosive, which is a mixture of inorganic explosives and organic explosives, CO₂ molecules can react with a plurality of reaction sites of lysozyme to produce a series of characteristic peaks signals such as m/z 1313 (1269+44), 1720 (1676+44), 1848 (1804+44), 2722 (2678+44).
