Quantitative Analysis of Pesticides in Food by LC/MS/MS and GC/MS/MS


Pesticide residue analysis is a vital aspect of testing to ensure a safe supply of fresh produce to consumers. The Canadian Food Inspection Agency requires that approximately 10,000 samples be tested annually for chemical residues. To accommodate these regulations, laboratories must perform robust and efficient pesticide analysis processes. To carry out the quantitation of pesticides in fruits and vegetables, CARO Analytical Services utilizes a QuEChERs extraction method with complementary LC/MS/MS and GC/MS/MS data analyses. In combination with streamlined data analysis workflows, these methods allow a parts-per-billion-level quantitative analysis on more than 350 samples on a monthly basis.

Upon completion of this webinar, attendees will be able to:

  • Comprehend the use of the QuEChERs extraction method with complementary LC/MS/MS and GC/MS/MS data analysis
  • Achieve a parts-per-billion-level quantitative analysis of pesticides in fruits and vegetables
  • Appreciate the advantages of streamlined data analysis workflows
