GC–MS/MS method for age determination of fingerprints

This work focuses on the monitoring of changes in the time and incident light dependent ratio of endogenous analytes, squalene, and pentadecanoic acid, in fingerprint samples by gas chromatography with tandem mass spectrometry. The method can be used for fingerprint age determination of two age diff...

Description
Summary:This work focuses on the monitoring of changes in the time and incident light dependent ratio of endogenous analytes, squalene, and pentadecanoic acid, in fingerprint samples by gas chromatography with tandem mass spectrometry. The method can be used for fingerprint age determination of two age different samples on a glass surface from the same donor or allows identity determination from fingerprints of different persons imprinted at the same time, even in case of their blurring on a glass surface.
