This study described the simultaneous direct determination of glyphosate and AMPA in oat flour by IC-MS. Glyphosate and AMPA can be determined sensitively and accurately using a Dionex IonPac AS19-4 μm column and ISQ EC single quadrupole mass spectrometer. The Reagent-Free ion chromatography system provides excellent reproducibility, thereby yielding greater quantification accuracy and consistently reliable results.
This study describes the simultaneous direct determination of endothall, glyphosate, AMPA, and glufosinate in drinking water by IC-MS. The four pesticides can be determined sensitively and accurately using a Dionex IonPac AS19-4μm column and an ISQ EC single quadrupole mass spectrometer.
Food safety and perceived health risks from residual agricultural chemicals are ongoing public concerns, and these chemicals are under increasing regulatory scrutiny, including polar pesticides. Much of the attention is focused on glyphosate because of its of wide use and association with crops and seeds genetically modified to tolerate glyphosate. In this application note, fast determination of multiple anionic pesticides and disinfection byproducts by IC-MS is demonstrated. All analytes of interest elute <14 min and were detected serially by suppressed conductivity and mass spectrometry.
A new workflow based on a modified QuPPe method and IC-MS/MS supports simultaneous multi-residue analysis of grape samples for polar pesticides. The IC-MS/MS method was developed using a Thermo Scientific™ Dionex™ IonPac™ AS19 4-µm column set and a compact IC system coupled to a Thermo Scientific™ TSQ Quantis™ triple quadrupole mass spectrometer. The results showed that the sensitivity, linearity,retention time precision, and recovery align with the SANTE/11813/2017 method performance criteria. The method provides lower LOQs than EU MRLs.
Food safety and perceived health risks from residual agricultural chemicals are ongoing public concerns, and these chemicals are under increasing regulatory scrutiny. The polar pesticides are one category, which include ionic post-emergent and desiccant herbicides, fungicides, growth-regulating chemicals, and the resultant metabolites of those compounds (Table 1 in the attached application note).
