Note: the training will only take place with a minimum of 10 participants and is limited to a maximum of 20 participants. Registrants will receive confirmation by April 2^nd 2026 at the latest.  

The training will focus on two pesticides residue analysis challenges:

• Extension of the scope of multi-residue analysis beyond the target quantitative scope using LC-HRMS-based chemical screening;
• Quantitative determination of pesticides not amenable to multi-residue analysis, using two multi-SRM methods.
  
  

The participants will be divided into two groups, and the training will be given in parallel sessions, with switching of the groups during the event.  

LC-Q-HRMS workflow for detection of targeted and untargeted pesticides

The aim of the training is to provide an introduction to pesticide screening analysis using Liquid Chromatography coupled to Orbitrap high resolution mass spectrometry (LC-Q-HRMS) combining theory and practical application. The theoretical part covers the fundamentals of high-resolution mass detection, the relevant parameters in setting up of a suspect/non-target screening workflows and the different strategies for processing the data. During the hands-on session the attendees will be involved in sample preparation, set up proper LC-HRMS acquisition methods, and perform data processing. By the end of the training, participants will be able to perform quant/qual pesticide screening and understand key parameters influencing the results.

Highlights:

• LC-HRMS data acquisition and processing workflows for target and suspect screening
• Understanding the fundamentals and key parameters of high resolution mass spectrometry
• Enhancing multi-residue pesticide detection using high-resolution mass spectrometry
  
  

Multi- single residue method (SRM) pesticides analysis

The goal of this training is to provide theoretical and hands-on guidance on analyzing highly polar compounds in challenging matrices. The training also addresses how to navigate the wide range of commercially available HILIC columns and select the right option for different applications. Finally, it covers key aspects of method settings and data processing to ensure robust and reliable results.

Highlights

• Analysis of 15 highly anionic polar pesticides and metabolites, including glyphosate, AMPA, glufosinate, ethephon, fosetyl, chlorate and perchlorate.
• Analysis of 17 highly cationic polar pesticides, including diquat, paraquat, matrine, oxymatrine, ETU and PTU.
• How HILIC can be used as an alternative to derivatization procedures and the importance of isotopically labeled internal standards use.
