The development of various analytical MS methods to investigate the chemical composition of liquids used in electronic cigarettes and characterize their quality is presented in this study.
Here, degradation compounds similar to those formed in metabolic or environmental pathways were generated by adopting a photocatalytic process, quantified in environmental samples by liquid chromatography with multiple-stage mass spectrometry (LC–MSn) analysis using an orbital trap instrument with an electrospray interface, and then identified in indoor environments alongside parent compounds.
