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-MSTheconstituentsandDetectionmethodsofhumanbodyodorAbstractHumanbodyodorhasthefunctionofthepheromone,studyofcompositionandnatureofhumanbodyodoriscrucialtotheinvestigation,medicalscienceandotherfields.Humanbodyodorhasthefunctionofthepheromone,studyofcompositionandnatureofhumanbodyodoriscrucialtotheinvestigation,medicalscienceandotherfields.Thispapergivesacomprehensivestudyoftheanalyticalproceduresofthehumanbodyodorsamples,whichwerecomparedwiththepreviousstudiesofhumanbodyodorsamplingsite,samplingmedia,pretreatmentmethodsandotheraspects.Odordetectionbydifferentdetectionmethods,aswellasdifferentpeople,foundthatbodyodorismainlycomposedoffattyacids,esters,alcohols,amines,ketones,andothersubstances.Andrepeatedanalyzesthesimilarityofthechromatogramsofthesameindividualodorsamples.Thisthesisisbasedonasummaryofpreviousresearchmethods,aroundthecompositionofbodyodorandtestmethodsforthethemeofusingSPEMtechnology,technicaldesignofexperimentsbyGC-MS,andhavethequalitativeanalysisandtherelativeamountofcomparisonofhumanaxillaryodor.Keywords:BodyOdor;ComponentAnalysis;SPEM;GC-目录1引言....................................................................11.1人体气味概况..........................................................11.2人体气味的应用........................................................21.3国内外对于人体气味研究................................................32人体气味的检测方法......................................................52.1提取与浓缩............................................................52.1.1固相微萃取法(SPME)................................................52.1.2样品预浓缩捕集(SPT).................................................62.1.3两种预处理方法的比较................................................72.2检测与分离............................................................83人体气味成分检测实验设计................................................93.1实验仪器..............................................................93.2实验步骤..............................................................93.2.1样品采集............................................................93.2.2样品的预处理.......................................................103.2.3色谱条件...........................................................103.3结果预测及处理.............
