Discover a New Robust Approach to High-throughput Glyphosate Analysis

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 quarternary 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.

WimBroer.pngDr Wim Broer, manager for science and development at Nofalab, and expert in the field of food and feed safety, will give an overview of the method and demonstrate long-term stability, robustness and validation results. The developed method meets the Sante requirements regarding reproducibility (<20%) and recovery (80-110%). The LOD of the method is below 0.01 mg/kg.
