Problems analysing polar pesticides? Need some help finding a good method? If so, this upcoming presentation may be what you're looking for...

The direct analyses of glyphosate and other polar pesticides like glufosinate, fosetyl, ethephon, chlorate and their metabolites with LC-MS is well described in the EURL QUPPE-method.

However, the chromatographic separation is not robust and a lot of maintenance is required. For glyphosate, AMPA and glufosinate, a known robust method is to derivatize these compound with FMOC. This method is laborious and one still need a separate method for the other pesticides.

At Nofalab a robust method is developed on a SCIEX 6500+ using a Shimadzu UHPLC system.

Basically, the chromatographic separation is performed on a Polyvinyl alcohol with quaternary ammonium groups column at pH 9. These conditions puts the glyphosate in the ideal configuration allowing a stable separation while the other anions are still well separated.

The LOD of the method is below 0.01 mg/kg.
