Event Overview: 
The trend for multi-residue pesticide analysis is towards faster, simpler, more generic methods of extraction with minimal, if any, clean-up to facilitate higher sample throughput. But this approach can result in extracts with high levels of matrix co-extractives, which will inevitably lead to faster contamination of LC–MS/MS and especially GC–MS/MS systems. The reluctance to use a cartridge SPE clean-up step most likely results from the time required for manual procedures and time taken to achieve the optimum balance between removal of co-extractive without loss of analytes.

This webinar will highlight an automated optimized online miniaturized cartridge clean-up approach providing more effective clean-up of QuEChERS extracts to overcome the analytical challenges faced by laboratories undertaking pesticides residues analysis.

Key Learning Objectives:

  • Understand the configuration, operation, flexibility and ease of use of an automated on-line µSPE setup with GC–MS and LC–MS analysis

  • Learn how optimized sorbent blends can yield excellent results from GC–MS/MS and LC–MS/MS multi-residue pesticides analysis in different sample types

  • Discover how µSPE can increase robustness, reduce system maintenance and increase laboratory productivity
