Event Overview:
Accuracy and precision in analytical testing can be difficult in cannabis matrices, as the high concentration of cannabinoids, terpenes, and other plant metabolites may cause chemical interferences, not to mention the fact that those interferences change with the variety of cannabis and hemp matrices that require testing. This is especially true for pesticides and mycotoxins where the low maximum residue limits (MRLs) and a generally high number of residues required for testing may lead to disproportionate issues with chemical interferences. The work discussed here will cover:

  • The quantification of 106 pesticide residues to evaluate matrix effects as a function of three cannabis sample types
  • The benefits of a high sample dilution ratio that are facilitated by sensitive hardware
  • How to set-up your analytical methods to ensure high quality data in different cannabis matrices

Key Learning Objectives:

  • Understand that each cannabis matrix will present different analytical challenges and knowing how to ensure data quality in these situations is critical
  • Explore the benefits of a high sample dilution ratio to understand how instrument sensitivity can be a competitive advantage

Who Should Attend:

  • Laboratory directors/managers
  • Laboratory QA/QC
  • Technicians
  • Method developers
  • Analysts
