This study is focused on finding an optimal preparation of the human scent samples for their detailed chemical analysis in connection with the possible forensic identifications of human individuals in the future. At the present time, the scent identification of people is carried out nearly exclusively using specially trained dogs. It is assumed that the human scent contains a certain group of compounds which allows the identification of people, the so-called human scent signature; however, its chemical composition is completely unknown, as of now. The principal problem of human scent studies consists in the very low concentrations of thousands of the scent compounds, whereas their relative concentrations are usually dramatically different. It seems to be obvious that the most appropriate analytical technique for these thousands of different chemical compounds is GC/MS. However, it is also necessary to find the most suitable sorbent material for human scent collection, an extraction solvent, and a pre-concentration technique. The selection of the appropriate gas chromatographic method is also important to achieve the optimal resolution of the targeted compounds. Of course, in the first instance, it is necessary to decide what it means “the most suitable” for human scent chemical analysis.

用于化学分析的人体气味样品

这项研究的重点是找到一种用于人类气味样品的最佳制备方法，以便对其进行详细的化学分析，并与将来可能对人类进行的法医鉴定相关联。目前，人们的气味识别几乎完全是使用受过专门训练的狗来进行的。假定人的气味中含有一定种类的化合物，这些化合物可以识别人，即所谓的人的气味特征。但是，到目前为止，它的化学成分还完全未知。人类气味研究的主要问题在于成千上万种气味化合物的浓度非常低，而它们的相对浓度通常差异很大。显然，针对这数千种不同化合物的最合适的分析技术是GC / MS。但是，还必须找到最适合人类气味收集的吸附剂，萃取溶剂和预浓缩技术。选择合适的气相色谱方法对于获得目标化合物的最佳分离度也很重要。当然，首先必须确定对人体气味化学分析“最合适”的含义。选择合适的气相色谱方法对于获得目标化合物的最佳分离度也很重要。当然，首先必须确定对人体气味化学分析“最合适”的含义。选择合适的气相色谱方法对于获得目标化合物的最佳分离度也很重要。当然，首先必须确定对人体气味化学分析“最合适”的含义。
