Two alternative approaches based on gas chromatography coupled to tandem mass spectrometry (GC–MS/MS) were developed to control the maximum residue limit of the banned insecticide, ethylene oxide (EtO), and its transformation product, 2-chloroethanol (2-CE).
The challenges that arise during cannabis metabolomics analysis using ultrahigh-performance reversed-phase liquid chromatography coupled with high-resolution tandem mass spectrometry (UHPLC–reversed-phase–HRMS/MS) are presented.
The advantages provided by the implementation of ion mobility spectrometry (IMS), and in particular travelling wave ion mobility spectrometry (TWIMS), in traditional liquid chromatography–mass spectrometry (LC–MS) systems are discussed.
LCGC Europe spoke to Irma Bongers from Wageningen Food Safety Research (WFSR) in The Netherlands, about a recent research project to analyze prohibited pharmaceutical active substances (PPAS) in milk.
