A Note on a Computerized System for Pattern Recognition Designed for Gas Chromatograms
The aim of this research project was to identity a range of odorous volatiles in human sweat which are under genetic influence and might be used as a basis for recognizing an individual in a similar way to fingerprinting. Assuming that such a range of compounds should have a similar pattern in identical twins, we have analyzed sweat samples from ten pairs of twins. These have been run on a gas Chromatograph equipped with head space desorption facilities and an outlet splitter allowing successive peak fractions to be collected. The fractions have been presented to a trained dog for scent matching as described elsewhere .
