PAH (Polycyclic Aromatic Hydrocarbon) compound are common molecules found in the environment as well as Crude Oil. Some PAH are significant pollution source in the human body or the environment. In addition, PAHs include several isomers. It is important to analyze PAH compounds including structural isomers. One of the most widely used methods for PAH compounds is Liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS). However, only a few publications reporting high resolution MS/MS spectra of PAHs are currently available. In addition, further limited number of publication is available focused on energy dependent MS/MS spectra of PAHs. In this study, it is hypothesized that obtaining MS/MS spectra with different collision energies and comparing the energy dependent pattern can be a useful tool to distinguish PAH isomers. To test the hypothesis, MS/MS spectra of 50 PAH compounds were obtained at various collisional energy and fragmentation patterns of PAHs depending on collisional energy were compared. Our results show that PAH isomers could be successfully distinguished from their significantly different relative ion intensity in the spectra obtained with various collision energies.
