Executive Summary

Pesticide residue testing in complex food and botanical matrices pushes GC‑MS/MS systems to their limits. Heavy coextracted interferences, diverse analyte chemistries, and increasing sensitivity requirements can overwhelm traditional workflows. Challenging matrices, such as roots, spices, and oils rapidly degrade standard GC columns, driving up maintenance and slowing laboratory productivity.

Discover a new approach to tackling these high‑matrix challenges. Our experts will share data from a study evaluating an advanced GC column engineered for long‑term robustness and matrix resilience, delivering stable retention times, improved peak shape, and strong signal‑to‑noise across thousands of real‑world injections.

Key Learning Objectives

  • Learn tips and tricks from industry expert on multi-pesticide analysis by GC-MS/MS.
  • See how novel GC technology and formats can bring sensitivity and peak shape improvement.
  • Understand how to reduce MS maintenance and improve lab throughput.
  • Learn how to handle challenging food matrices and extend column lifetime.

Who should attend?

  • Food Analysis scientists interested in improving GC-MS/MS method.
  • Lab chemists interested in extending calibrations over longer periods of time and improving column lifetime.
  • Analytical chemists who would like to learn about mitigating challenging matrices.
