The Research Of Difference Of Human Body Odor In Identification

The plicedog identification depends on odor. It is the traditional field that the policedog identifies human body odor. Because of difference of human body odor,the policedog can use it. Although we have not been studied well on human body odor now, the policedog has used the difference of human body odor very well. With the development of science and technology, we are going to research the difference of human body odor by scientific instruments to promote the development of the policedog technology.The first, tracking experiments of an individual sample in 30 days are done by policedog and GC/MC. The samples are saved in the refrigerator for 4℃. It is indicated that the constituents of the samples change slightly. The second, we study the different individual odor and find that the policedog is unable to carry on the classification recognition. But we can know the difference of them by GC/MC. This is a scientific instrument and the policedog technology combined with each other to provide a meeting point, and as police dog technology provides the necessary supplement. At last, we study fingerprint characteristics of the chromatograms from human body odor.Maybe, the segment of chromatogram that we get is the fingerprint characteristics.
