Improving multiresidue pesticide GC‑MS/MS reliability through GC column longevity

Pesticide residue testing in complex food and botanical matrices pushes GC‑MS/MS systems to their limits. Heavy co‑extracted 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.
In this SelectScience® webinar, 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.
Residue and pesticide testing specialist Carlos Parra of NOW Foods, alongside Colton Myers from Restek Corporation, will discuss how this innovative design boosts sensitivity and extends column lifetime to help labs achieve cleaner, more confident pesticide results.¨
