Karolinska University Hospital researchers recently tested new approaches for analyzing drugs of abuse in oral fluids.

A combination of liquid chromatography ion mobility spectrometry, and high-resolution mass spectrometry (LC–IMS-HRMS) for non-targeted analysis (NTA) was used to detect and identify per- and polyfluoroalkyl substances (PFAS) in alligator plasma.

University of Caldas and University of Chile researchers extracted estrogenic hormones from wastewater samples using rotating disk sorption extraction. After extraction, the concentrated analytes were measured using liquid chromatography coupled with photodiode array detection (HPLC-PDA).

Catharina Capitain and Melanie Schüßler from the Faculty of Geosciences at the University of Tübingen, Tübingen, Germany describe a novel approach using matrix-matched semiquantification to investigate per- and polyfluoroalkyl substances (PFAS) in contaminated soil.
