Enhanced Detection of Oxygenated Polycyclic Aromatic Hydrocarbons Using Atmospheric-Pressure Chemical Ionization-Mass Spectrometry

Polycyclic aromatic hydrocarbons (PAHs) and their oxygenated derivatives (oxy-PAHs) are highly toxic carcinogens that present a significant hazard to human health. To fully understand the risks associated with exposure to PAHs, robust analytical methods for their detection are required. Mass spectrometry coupled with ultrahigh-performance liquid chromatography (UHPLC–MS) has proven to be a powerful technique for the analysis of these compounds. This article looks at the benefits of using atmospheric-pressure chemical ionization (APCI) in the place of traditional electrospray ionization (ESI) for the detection of oxy-PAHs.
