Forensic applications of direct analysis in real time (DART) coupled to Q-orbitrap tandem mass spectrometry for the in situ analysis of pigments from paint evidence

Paint evidence found at a vehicle accident site may reveal a connection between the victim and the responsible vehicle. During an accident, as paint chips or paint smears are often transferred between vehicles, the comparison of the transferred paints between the victim ’s vehicle and the suspected vehicle can serve as important evidence in reconstructing the scene of the accident. Typically, modern vehicle paint is composed of four main layers: an electrocoat primer, a primer surfacer, a base coat, and a clear coat [1,2].
