Analytical workflow facilitates pesticide residue testing

Thermo Fisher Scientific’s validated ion chromatography tandem mass spectrometry (IC-MS/MS) analytical workflow is designed to enable food testing laboratories to overcome the challenges associated with IC-MS/MS analysis of polar anionic pesticides in complex sample matrices.

The Thermo Scientific Anionic Pesticides Explorer is a high-throughput, sample-to-result, IC-MS/MS-based analytical workflow, comprising the Thermo Scientific Dionex Integrion High Performance Ion Chromatography system coupled with the Thermo Scientific TSQ Altis Triple Quadrupole MS, for the multi-residue detection, identification and quantification of anionic pesticides at low concentrations in complex food matrices.

Anionic polar pesticides, such as glyphosate, are widely used in agriculture, but are difficult to analyse using LA-MS/MS-based methods. This has contributed to the infrequent monitoring of these pesticides in the global food chain.

The out-of-the-box, easy-to-implement, analytical workflow provides food testing laboratories with increased workflow productivity and simple methodology through access to a single multi-residue method for high-priority anionic polar pesticide and metabolites. It also offers enhanced chromatographic retention, resolution and sensitivity with modified Quick Polar Pesticides Method (QuPPe) sample preparation protocol for a wide range of matrices.

Thermo Fisher Electric also provides a fully documented, ready-to-run workflow supported by a system-suitability test and detailed guidance documents, enabling consistent performance during routine operation, according to EU SANTE method performance criteria.
