Complex food matrices can challenge even well-validated residue screening methods. Co-eluting matrix components may suppress ionization, leading to underestimated results and putting data integrity at risk.
This infographic outlines a six-step multi-residue screening workflow, from sample homogenization and QuEChERS extraction to GC-MS/MS and LC-MS/MS acquisition and final quantitation.
