The Scent Trace of a Professor from Chemicke Listy

We do not presume that professor Barek has committed any criminal act, but, if we nevertheless collect his scent sample and conduct a detailed chemical analysis, we could confirm that he is male, of the Caucasian race, and perhaps determine which blood type flows in his veins, whether it is A, B, or 0. Scent evidence is a source of information that prosecuting authorities have been using for decades to identify individuals through specially trained canines. There is now an effort to create an instrumental method for a detailed chemical analysis of the scent trace so that scent identification can be objectified and used as an evidence in court, and of course, to provide a range of additional pieces of information about the scent provider.
