Scientists at the Norwegian Defence Research Establishment (Kjeller, Norway) are working in collaboration with the University of Oslo (Oslo, Norway) to develop new methods to detect the illicit use of nerve agents. In a recent study published in the journal Analytical Chemistry, the team presented a novel method for the quantification of nerve agent metabolites in human serum and urine by combining salting-out assisted liquid–liquid extraction (SALLE) and on-line solid-phase extraction–liquid chromatography–tandem mass spectrometry (SPE–LC–MS–MS).
