人体气味的成的分以及检测方法.doc

PAGE  人体气味的成分以及检测方法 摘 要 人体气味是人体在新陈代谢过程中产生的气味。据生物学家测定，人体气味中含有好几百种化学物质。在刑侦方面：体气味追踪罪犯, 进行人体气味的比对鉴别。利用警犬根据罪犯的特异性气味来抓捕犯罪分子。在医学方面，它是一种信号，能够帮助人们诊断疾病，当人的健康状况发生变化时，由体内排出的化学物质的成分也会随着发生变化，训练有素的医生可借助体味的辨别对某些疾病进行诊断。而有的体味甚至是是一种潜形药物，能帮助人们治病。另外，研究体味成分对香水、抑汗剂等去体味产品的开发起到指导、和推进作用。人体气味具有信息素的功能，研究人体气味的组成及性质对于刑侦、医学等领域具有重要的意义。本文全面研究了人体气味样品的分析程序，对以往研究人体气味的采样部位、采样介质、预处理方法等环节进行了比较。通过不同的检测方法，以及对不同的人进行体味检测，发现人体气味主要是由脂肪酸、酯、醇、胺、酮等物质组成,。并且多次分析同一个体气味样品的色谱图有较好的相似性。本论文还根据对以往研究方法的总结，围绕人体气味的组成及检测方法为主题，利用SPEM技术，与GC-MS技术设计实验，对人体腋窝的气味进行定性分析，以及相对量的比较。 关键词：人体气味；成分分析；SPEM；GC-MS The constituents and Detection methods of human body odor Abstract Human body odor has the function of the pheromone, study of composition and nature of human body odor is crucial to the investigation, medical science and other fields. Human body odor has the function of the pheromone, study of composition and nature of human body odor is crucial to the investigation, medical science and other fields.This paper gives a comprehensive study of the analytical procedures of the human body odor samples, which were compared with the previous studies of human body odor sampling site, sampling media, pretreatment methods and other aspects. Odor detection by different detection methods, as well as different people, found that body odor is mainly composed of fatty acids, esters, alcohols, amines, ketones, and other substances. And repeated analyzes the similarity of the chromatograms of the same individual odor samples. This thesis is based on a summary of previous research methods, around the composition of body odor and test methods for the theme of using SPEM technology, technical design of experiments by GC-MS, and have the qualitative analysis and the relative amount of comparison of human axillary odor.
