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.

LC Column Technology: The State of the Art

In this extended special feature to celebrate the 30th anniversary edition of LCGC Europe, leading figures from the separation science community explore contemporary trends in separation science and identify possible future developments. We asked key opinion leaders in the field to discuss the current state of the art in liquid chromatography column technology, gas chromatography, sample preparation, and liquid chromatography instruments. They also describe the latest practical developments in supercritical fluid chromatography, 3D printing, capillary electrophoresis, data handling, comprehensive two‑dimensional liquid chromatography, and multidimensional gas chromatography.
