A tandem mass spectrometric investigation of the collision-induced dissociation of five commonly prescribed psychoactive pharmaceuticals, risperidone, sertraline, paroxetine, trimipramine, and mirtazapine, and their metabolites has been carried out. Quadrupole ion trap mass spectrometry was employed to generate tandem mass spectrometric (MS/MS) data of the compounds under investigation and structural assignments of product ions were supported by quadrupole time-of-flight mass spectrometry. These fragmentation studies were then utilised in the development of a liquid chromatographic method to identify the drugs and their metabolites in human hair and saliva samples, thus providing relevant profiling information.
