We studied the analysis of pyrolysis products, or smoke components, from the blood of charred bodies. The analysis method included cryogenic-focusing gas chromatography-mass spectrometry following solid-phase micro-extraction of the volatile compounds from the headspace of a blood sample vial. Using this method, pyrolysis products such as phenylacetylene, styrene, indene, and naphthalene were detected from the blood of charred bodies that had accompanying heat wounds. The smoke components generated from a fire event being found in a charred body's blood could serve as evidence of the charred body having been alive at the start of the fire.

我们研究了对烧焦尸体血液中的热解产物或烟雾成分的分析。分析方法包括从血样瓶顶部空间固相微萃取挥发性化合物后进行低温聚焦气相色谱-质谱分析。利用这种方法，从伴有热伤的烧焦尸体的血液中检测到苯乙炔、苯乙烯、茚和萘等热解产物。在烧焦尸体的血液中发现火灾事件产生的烟雾成分可以作为烧焦尸体在火灾开始时还活着的证据。
