不同部位人体气味的分析研究

Study on analysis of human odors from different regions

运用SPME-GC/MS法对同一个体腋窝部、手部和足部的人体气味样品进行了采样分析,通过比较3个部位人体气味样品色谱图中共有成分相对峰面积比和非共有成分,结合使用相似度法对3个部位的人体气味进行了比较分析,三者具有较高的相似度,但仍存在一些细微的差别。

Human odor samples from different regions （including axillary region, hand region and foot region） were analyzed by SPME-GC/MS, and these human odor samples were identified by comparing the difference in the relative peak area ratios of common compounds and uncommon compounds in samples. These human odor samples from three regions in the same individual were also identified by Semblance method. There was some good semblance in three samples, and a little differences existed in them too.
