The analysis of residual pesticides in food is critical to protecting consumer health and ensuring compliance with global regulatory limits. This application note demonstrates the determination of pesticide residues in grapes using gas chromatography–mass spectrometry (GC-MS) with a single quadrupole detector. The method, performed on a SCION 8500 GC coupled to an 8700 MS and 8400 PRO autosampler, combines QuEChERS sample preparation with selective ion monitoring (SIM) to deliver excellent sensitivity, linearity, and repeatability. The results highlight a robust and reliable approach for routine pesticide residue analysis in fruit matrices.

Key learnings from this application note :

1. Discover how using SCION instruments’ GC-MS (SQ) can be used to analyze residual pesticides in grapes by Selective Ion Monitoring (SIM) to identify and quantify target analytes with confidence.
2. Learn how QuEChERS AOAC buffered method can be used to prepare grapes samples to make them suitable for analysis by GC-MS.
3. Understand the importance of spiking samples to calculate recovery in order to evaluate the performance of the analytical method to ensure accurate and valid results.
