Benzo[a]pyrene (B[a]P) is a well-known carcinogenic compound found in tobacco products and tobacco smoke. The Cooperation Centre for Scientific Research Relative to Tobacco (CORESTA) has recommended a gas chromatography/ mass spectrometry (GC/MS) method to determine concentrations of B[a]P in tobacco products. In the proposed method, B[a]P is extracted from the tobacco with methanol, followed by a solid phase extraction (SPE) and subsequent concentration prior to GC/MS analysis. The CORESTA recommended method is time-consuming, especially in sample preparation procedures, and showed low sensitivity. In this application note, a simple, reliable and fast analytical method for the determination and quantification of B[a]P in tobacco products has been developed using a PerkinElmer QSight® LX50 UHPLC system, coupled to a PerkinElmer QSight 220 MS/MS detector.
