Prague, November 4, 2019 – RAFA 2019 – A new, effective ion chromatography-tandem mass spectrometry (IC-MS/MS) analytical workflow aims to enable food testing laboratories to overcome challenges associated with analyzing polar anionic pesticides in complex sample matrices using liquid chromatography-tandem mass spectrometry (LC-MS/MS).

The Thermo Scientific Anionic Pesticide Explorer is a high-throughput, sample-to-result IC-MS/MS analytical workflow. It combines the Thermo Scientific Dionex Integrion High-Performance Ion Chromatography System with the Thermo Scientific TSQ Altis Triple Quadrupole MS for the multi-residue detection, identification, and quantitation of low-concentration anionic pesticides in complex food matrices. Thermo Fisher Scientific will showcase this new analytical workflow at the 9th International Symposium on Recent Advances in Food Analysis (RAFA), held from November 5 to 8 at the Clarion Congress Hotel in Prague, Czech Republic (Booth 8).

"Anionic polar pesticides such as glyphosate are widely used in agriculture; however, the difficulties involved in analyzing them using LC-MS/MS-based methods have resulted in limited monitoring of these pesticides across the global food supply chain—a situation that concerns both consumers and regulatory bodies," said Khalil Divan, Senior Director of Food & Beverage, Chromatography and Mass Spectrometry at Thermo Fisher Scientific. “The Anionic Pesticides Explorer is an out-of-the-box, easy-to-implement analytical workflow that enables food safety laboratories to enhance monitoring and throughput for the quantitation and identification of multiple anionic pesticides in a single analysis.”

Katie Banaszewski, Method Development Manager at NOW Foods, stated: “As a manufacturer of naturally derived supplements and nutritional products, ensuring the safety of incoming materials is paramount, and pesticide testing is critical to verifying this. The Anionic Pesticides Explorer allows us to boost testing workflow productivity by reliably detecting multiple pesticide residues across diverse sample matrices within a single, sensitive analytical solution.”

The Anionic Pesticides Explorer is designed to provide food testing laboratories with:

Increased workflow productivity and simplified methodology by using a single multi-residue approach to handle high-priority anionic polar pesticides and metabolites.

A robust method that improves chromatographic retention, resolution, and sensitivity—suitable for a wide range of matrices—through an enhanced QuPPe (Quick Polar Pesticides) sample preparation protocol.

A fully documented, ready-to-run workflow supported by system suitability testing and detailed guidance documentation, ensuring optimal performance during routine operations in accordance with EU SANTE method performance criteria.
