This reference guide provides examples of recommended, proven, and robust gas chromatography/tandem mass spectrometry (GC/MS/MS) methods for pesticide multiresidue analysis using Agilent triple quadrupole GC/MS/MS systems. The majority of pesticide laboratories have transitioned from GC/MS to GC/MS/MS techniques due to enhanced sensitivity and selectivity, especially in the presence of coeluting matrix interference. Included in this guide are practical tips and considerations for method development, optimization, modification, and routine use. Important aspects of GC and MS/MS analysis of pesticides are discussed, especially when dealing with matrix-related issues that are largely affected by the chemical composition of the analyzed sample extract.
The basics of sample preparation in pesticide multiresidue analysis are also covered with a focus on the Quick, Easy, Cheap, Effective, Rugged, and Safe (QuEChERS) approach. Additional topics include the best practices for setting up and configuring a triple quadrupole GC/MS system (GC/TQ) for hydrogen carrier gas, dMRM/scan acquisition mode, and advances in software tools, such as the Agilent MassHunter Optimizer for GC/TQ.
Four GC/MS/MS methods are included in Annex IV to Annex VII at the end of this guide. The first two methods (Annex IV and Annex V) are legacy methods used by the authors as a reference for method development and optimization. The second two methods (Annex VI and Annex VII) present the recommended instrument configuration, GC columns, consumables, and method parameters for the best method performance with helium and hydrogen as carrier gases.
This 110-page reference guide is divided into the following topics:
- Pesticide multiresidue analysis
- Sample preparation using the QuEChERS approach
- Use of internal and quality/process control standards
- GC analysis of pesticides
- MS/MS detection considerations
- GC/MS/MS method development and optimization examples
- GC/MS/MS method modification for a different list of analytes
- GC/MS/MS routine analysis
