Mass Spectrometry: Reveal Secrets There is something unique pattern in fingerprints of an individual which constitute of valleys and ridges. Mass Spectrometry imaging of chemical compounds in fingerprints help in determination of lifestyle of an individual. Mass spectrometry imaging visualizes the spatial relationship of each compound detected, allowing ridge detail and chemical information in a single analysis. The presence of a single compound may not be sufficient to provide detailed information about an individual, but the compilation of multiple compounds present in a latent fingerprint may give insight into one’s lifestyle. Chromatography and mass spectrometry coupled methods, such as liquid chromatography-mass spectrometry (LC-MS) and gas chromatography-mass spectrometry (GC-MS), provide chemical fingerprint information, but typically require multiple fingerprints with no spatially relevant information. The multiplex method allowed MS/MS of citric acid, tartaric a...
