NIR analysis of hair samples as a possible forensic chemistry tool: identifying smoker and nonsmoker persons

Abstract In the present report it is shown that a chemometric analysis of near infrared spectroscopy (NIR) data obtained for hair samplescan be successfully employed to differentiate between smoker and nonsmoker persons. It is worth noting that only NIR data are enough to such identification, with no kind of classical chemical analysis been necessary. Such achievement demonstrates that a chemometric analysis of hair based on NIR spectra has possible applications in forensic chemistry.
