Recent Developments in Pesticide Analysis in Food and Cannabis

Anastasia Andrianova, Applications Scientist, Agilent Technologies
Karen Yannell, Applications Scientist, Agilent Technologies

The analysis of pesticides residues has evolved significantly over the last 30 years. Recent developments have allowed further improvements to be made in sensitivity, robustness, sample screening, ease of method setup and data processing for both GC/MS and LC/MS technologies – leading to greater information from your samples.

This presentation will highlight some of these developments in the analysis of food and cannabis including:

  • The optimization of the GC injection parameters for acetonitrile extracts without the need for solvent venting, or cool injections
  • A simplified set-up and configuration providing mid-column backflushing whilst simplifying the setup for pulsed splitless injection mode using a new pneumatic switching device (PSD)
  • The QuickProbe direct insertion sampling device for GC/MS and possible opportunities for rapid screening for food and environmental samples
  • A novel non-target pesticide screening workflow using high-resolution GC/Q-TOF and LC/Q-TOF systems and accurate mass libraries of pesticides and environmental pollutants. Examples will highlight the complementary nature of the combined GC/Q-TOF – LC/Q-TOF capabilities with strawberries and GC/Q-TOF for the detection of residues in cannabis
  • A simplified software tool for food authentication utilizing LC/Q-TOF data

Glyphosate Revisited, a Direct LC/MS/MS Method for Food Samples

Jerry Zweigenbaum, Senior Research Scientist, Agilent Technologies

Glyphosate is still in the news with major jury awards in California and analysts around the world are testing samples for the presence of this compound and its metabolites. A method using QuPPE and LC/QQQ without derivatization will be described. This interactive user presentation will discuss what is needed to run the analysis with good reproducibility and sensitivity. Those little things that make a big difference will be described and deliberated.
