Determination of Highly Polar Pesticide Residues in Food of Plant Origin by an Automated QuPPe Solution
22 Jan 2016This application note evaluates the performance and versatility of the AutoMate-Q40 for the extraction of highly polar pesticides using the QuPPe Method. Liquid Chromatography coupled to triple-quadrupole mass spectrometry (LC-MS/MS) was employed for the detection of highly polar pesticides in agricultural commodities. Quantification was based on matrix-matched calibration curves for each commodity. The AutoMate-Q40 streamlines the QuPPe Method while providing suitable analytical results falling in the method guidelines (range of 70-120% and RSD <20%) for all target compounds.

LC-MSLC-MS (liquid chromatography-mass spectrometry) systems and equipment are used for separation and quantitative analysis of complex mixtures, combining liquid chromatography and mass spectrometry. Quantify proteins, contaminants, pesticides or screen for drug metabolites with a high level of sensitivity. LC-MS systems and equipment include reverse phase, normal phase and specialized columns integrated with various MS detectors such as time-of-flight (TOF), quadrupole, orbitrap or ion trap mass analyzers. LC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzer give greater sensitivity and resolving power to your analysis.
