Polar ionic pesticides, such as glyphosate, glufosinate, and chlorate which are - not amenable to common multi-residue methods are typically extracted using the QuPPe (Quick Polar Pesticides) method. In order to obtain sufficient chromatographic retention and acceptable peak shapes, individual extracts are analyzed multiple times using different chromatographic conditions which adds to the overall cost of sample analysis. The use of suppressed ion chromatography coupled to tandem quadrupole mass spectrometry can help to provide a more effective solution. This presentation will describe our experience, challenges, and successes in the development, validation, and implementation of this approach.
