The Challenges of Pesticide Analysis - LC or GC Triple Quadrupole?


Separation Science, in collaboration with
Thermo Fisher Scientific, offers the first instalment
of a three-part Instrument Selection Discussion Series where Laboratory Professionals gain knowledge on the choices of instrument available and which is most recommended for specific applications.

Format: On-demand

Duration: Approximately 1 hour







Ensuring the safety of the world’s food supply is critical, but identifying and quantifying contaminants such as pesticides can be a significant challenge, particularly in widely differing environments under a variety of regulatory frameworks.

This presentation, part 1 of the 'Instrument Selection Discussion Series' takes a look at the pros and cons of LC-QqQ and GC-QqQ for the analysis of pesticides in food and agricultural matrices. Industry and technology experts will provide their insights on the various instrumental setups and workflows for analysing real-work samples and aim to address questions such as:

  • What are the main challenges in the QqQ analysis of a comprehensive list of pesticides?
  • What are the most challenging sample matrices for pesticides analysis with QqQ instruments?
  • How can GC-MS/MS, LC-MS/MS or High Resolution Accurate Mass (HRAM) technology address counterfeiting issues?
  • Will laboratories use QqQ and HRAM as a complementary approach?
  • What will be the key improvements to these instrumental workflows in the near future? 

Our expert panelists for this discussion forum are:

Bert Popping (FOCOS)
Bert advises technology providers, food manufacturers, start-up companies, not-for-profit organizations, investors and laboratories on strategic food safety solutions and emerging technologies. Bert previously worked as Chief Scientific Officer and Director Scientific Development and Regulatory Affairs for global contract laboratories, and has 25 years of experience in the food testing industry.

Katie Banaszewski (NOW Foods)
Katie is the Analytical Lab Manager NOW Foods where she uses her 15 years of industry experience to lead, motivate and inspire a team of Analytical Chemists and Method Development Scientists. During her time at NOW, Katie has lead the development and implementation of a routine pesticide residue monitoring program and plays an integral role in growing the company’s analytical capabilities.

Łukasz Rajski (EURL-FV, University of Almería)
Łukasz is an expert in the development and validation of analytical methods for pesticide residues in food, working with advanced mass spectrometry techniques (both high-resolution and triple quadrupole) coupled to ultra-high performance liquid chromatography and high-performance ion chromatography.
