Identification, Quantitation and Confirmation of Pesticides in Food Samples using LC-MS/MS and Ultra-Fast Polarity Switching

This poster presents a new and powerful workflow to identify, quantify and confirm the presence of 300 pesticides utilizing generic QuEChERS extraction and LC-MS/MS analysis. This is performed with the SCIEX QTRAP^® 6500+ system using the Scheduled MRM™ Pro algorithm and ultra-fast polarity switching. High confidence in identification and confirmation was achieved by automatically calculating the ratio of quantifier and qualifier ions and searching MS/MS spectral libraries in MultiQuant™ and MasterView™ software.
