Direct Analysis of Glyphosate, Glufosinate and AMPA in Foods Using a Triple Quadrupole LC/MS/MS

Glufosinate and glyphosate are non-selective herbicides that are widely used in agricultural and household applications. In particular, grain is used as a pre-harvest pesticide to reduce the time and effort required for harvesting. Residue levels are set for each crop in each country. Glyphosate is metabolized in soil and water to aminomethylphosphate (AMPA). Glyphosate, glufosinate, and AMPA are highly polar compounds that are difficult to retain in reversed-phase mode in HPLC and LCMS, and are commonly analyzed by FMOC derivatization. Application News C 181 presented an example of direct analysis of glyphosate, glyphosate, and AMPA in drinking-water without derivatization.
In this report, derivatization is similarly omitted, and an example in which solid samples such as grains and fruits are pretreated by the QuPpe (Quick polar pesticides) method developed by EURL (Stuttgart, Germany) and directly analyzed is introduced.
