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.

Dr. Stuart Adams graduated with a BSc honors degree in agricultural, food and environmental chemistry from the University of Glasgow and a PhD in the analysis of pesticides from the University of Leeds in 2002. For the past 14 years he has gained a wealth of experience in food safety and environmental analysis at Fera Science Limited UK including expertise in IC-MS/MS. Dr. Adams has presented a number lectures on the topic of IC-MS/MS and firmly believes it is an essential technique in a modern food safety and environmental analytical laboratory.
