This article describes a direct analysis of glyphosate, aminomethylphosphonic acid (AMPA), glufosinate, and 3-methylphosphinicopropionic acid (MPPA) in water by liquid chromatography coupled to tandem mass spectrometry (LC–MS/MS) without derivatization. The chromatographic separation was performed using a hydrophilic interaction liquid chromatography (HILIC) column and typical LC–MS mobile phases. Method performance was evaluated, showing excellent results. The low limits of quantification (LLOQs) obtained meet the requirements of EU guidelines and could also be used to get an agreement in France where regulations require lower LLOQs (NOR: DEVL1703763V).
