Event Overview:

Pesticides play an important role in the agriculture and food industries to improve crop yield and food production. However, the quantity of pesticide residue remaining in or on commodities are tightly controlled to avoid contamination of the food chain and the environment. Therefore, regulatory agencies have set maximum residue levels (MRLs) for hundreds of pesticides and their metabolites. To check whether foods comply with these legal requirements, different analytical techniques are necessary to detect all pesticides that could be mandated for analysis. This webinar describes a comprehensive end-to-end workflow for the targeted quantitation of more than 1000 pesticides in tomato using GC/MS/MS and LC/MS/MS techniques with a common QuEChERS sample extraction protocol without further clean-up. The workflow performance was successfully evaluated according to the SANTE 11312/2021 guideline based on method sensitivity, limit of quantification, linearity, recovery, and repeatability using matrix-matched calibration standards for over 1000 pesticides.


Key Learning Objectives:

  • Understand why the right combination of sample preparation is critical in attaining meaningful pesticide residue results.
  • Learn how 1000 pesticides can be analyzed within 20 minutes instruments run times.
  • Learn how a dynamic MRM Method (dMRM) can improve the scope and efficiency of a multiresidue quantification.
  • Understand why the combination of GC/MS/MS and LC-MS/MS is necessary to determine all mandated pesticides.

Who Should Attend:

  • Private CRO food safety testing laboratories
  • Government food testing laboratories
  • Academic food science laboratories
  • Food Lab managers
  • Food Lab instrument operators

FACSS 2026 Award Interviews © Erin -chronicles-stock.adobe.com
SciX 2026 Award Winners: The Conversations Coming Next
Eight FACSS award winners at SciX 2026, One LIBS trailblazer. Forty-eight questions. And not one of them is a softball. Award season in spectroscopy usually means polite applause, a plaque, and a photo. We're not completely interested only in the award sessions. The eight scientists honored at SciX 2026 in Sparks, Nevada, along with LIBS researcher Alessandro De Giacomo, are pushing Raman into operating rooms, flying LIBS on drones, reading chemistry off Mars, and tracing toxic metals downwind of industrial sites. Their work makes big claims. In the coming days, Spectroscopy will sit down with eight of these researchers and ask whether those claims hold up. The interviews that follow won't just celebrate. They'll press on the gaps between simulation and experiment, between the lab bench and the clinic, and between a clever paper and an instrument someone will actually buy and use.

Spectral Frontiers: Past the Diffraction Limit (FT-IR Spectroscopy)
Past the Diffraction Limit: How Photothermal and Quantum Cascade Lasers Are Reinventing FT-IR Spectroscopy
Fourier-transform infrared (FT-IR) spectroscopy, long the workhorse of molecular fingerprinting, is being reinvented by photothermal detection schemes and quantum cascade laser (QCL) sources that push spatial resolution and analysis speed far beyond classical dispersive and interferometric limits. New instrumentation such as optical photothermal infrared (O-PTIR) microscopy and laser direct infrared (LDIR) chemical imaging is enabling sub-micron, label-free chemical mapping of biological, environmental, and pharmaceutical samples. This article reviews the latest FT-IR-adjacent technologies, recent patents, and research driving the field, featuring perspectives from the scientists and instrument developers advancing the technique.
