Applying High-Resolution Accurate Mass GC–MS for Quantitative Pesticide Residue Analysis

Recently, it was reported that millions of eggs contaminated with the insecticide fipronil had been distributed in more than 17 countries. This highlights the importance of appropriate methodologies for the analysis of pesticide residues that can keep scientists one step ahead to ensure the safety of consumers. High resolution accurate mass (HRAM) mass spectrometry coupled to gas chromatography (GC) provides a valuable tool to combat the threats to global food safety. As an alternate to GC–MS/MS, it provides a full scan non-targeted acquisition that allows target compounds to be decided post acquistion. This approach is reported in the literature to be highly suitable for pesticide residue analysis, and permits the simultaneous quantitative analysis of targeted residues while at the same time screening for pesticides not expected to be present in the samples—all in a single analysis and without compromising performance. In addition, HRAM mass spectrometry has an extended scope, not only in terms of the number of pesticides that can be considered in a single analysis, but also in terms of the breadth of the analytical applications that can be addressed.

In this webcast, Dominic Roberts will discuss the results of experiments and collaborator experiences with GC–HRAM mass spectrometry including:

  • Precision, accuracy, and identification capabilities in targeted workflows
  • Application of GC-HRAM mass spectrometry for quantitative pesticide residues
  • Ease of use for routine analysis
