目的 建立气相色谱质谱结合红外光谱法快速检验“毒镖”中复合成分的分析方法。方法 将乙酸乙酯加入“毒镖”的液体中,加碱形成白色沉淀,采用红外光谱法对白色沉淀进行定性分析,同时采用气相色谱质谱法对乙酸乙酯中的成分进行分析。结果 该方法能从案件检材中快速检出氯化琥珀胆碱和普鲁卡因成分,其中氯化琥珀胆碱红外光谱的相似度达到81.3%。结论 该分析方法操作便捷、实用,结果准确,适用于刑事案件中“毒镖”检材中复合成分的快速检验。
Abstract
Objective Aiming at developing a method for quick analysis of dart-carrying poison (poisoned dart) by gas chromatography-mass spectrometry (GC/MS) plus infrared spectroscopy. Methods The liquid carried with likely-poisoned dart was extracted with alkaline ethyl acetate and further tested by gas chromatography-mass spectrometry, with the white precipitate being analyzed by infrared spectroscopy. Results The results showed that both suxamethonium chloride and procaine were rapidly detected out of the liquid from poisoned dart, with suxamethonium chloride similar up to 81.3% retrieval by infrared spectroscopy. Conclusion This method is simple, sensitive and accurate, capable of using for rapid detection in casework.
