Event Overview:

Pesticides play an important role in the agriculture and food industries to improve crop yield and food production. However, the quantity of pesticide residue remaining in or on commodities are tightly controlled to avoid contamination of the food chain and the environment. Therefore, regulatory agencies have set maximum residue levels (MRLs) for hundreds of pesticides and their metabolites. To check whether foods comply with these legal requirements, different analytical techniques are necessary to detect all pesticides that could be mandated for analysis. This webinar describes a comprehensive end-to-end workflow for the targeted quantitation of more than 1000 pesticides in tomato using GC/MS/MS and LC/MS/MS techniques with a common QuEChERS sample extraction protocol without further clean-up. The workflow performance was successfully evaluated according to the SANTE 11312/2021 guideline based on method sensitivity, limit of quantification, linearity, recovery, and repeatability using matrix-matched calibration standards for over 1000 pesticides.

Key Learning Objectives:

• Understand why the right combination of sample preparation is critical in attaining meaningful pesticide residue results.
• Learn how 1000 pesticides can be analyzed within 20 minutes instruments run times.
• Learn how a dynamic MRM Method (dMRM) can improve the scope and efficiency of a multiresidue quantification.
• Understand why the combination of GC/MS/MS and LC-MS/MS is necessary to determine all mandated pesticides.

Who Should Attend:
