Optimization of the Method for Determining Ammonium Glucosinate and Its Metabolite in Agricultural Crops Using High-Performance Liquid Chromatography with Mass Spectrometric Detection
A method for the determination of glufosinate ammonium (GFA) and its metabolite 3-(methylphosphinico)propionic acid (MPPC) in potato and cereal crops by high-performance liquid chromatography-tandem mass spectrometry was proposed. GFA and MPPC were extracted from samples with an organic solvent. Identification of substances was carried out by retention time, quantitative determination – by the absolute calibration method. The selectivity of the method is ensured by a combination of sample preparation and chromatography conditions.
