Sample Prep and IC-MS/MS Workflows for Anionic and Cationic Pesticides

Welcome to Thermo Fisher Scientific's 2022 Transforming pesticide analysis with GC-MS, IC-MS, LC-MS, and data analysis e-seminar series. In this four-part eSeminar Series, we address the advances and new trends in pesticide residues analysis so that you can be well-equipped to stay ahead of developing challenges.

Join us for the second webinar in this series.

Sample Prep and IC-MS/MS Workflows for Anionic and Cationic Pesticides

Section 1: Sample preparation challenges and solutions for pesticides residue analysis. Sample extraction is the start of any analytical chromatography process and in food this can be more than a little challenging, discover some tips and tricks to help you get ahead.

Section 2: Ionic polar pesticides include some of the most frequently used pesticides worldwide but also present unique challenges to traditional methods of pesticide analysis.

Traditional extraction methods typically suffer from low extraction efficiency of highly ionic polar pesticides and RPLC methods have very poor retention of highly ionic polar pesticides. Advances in the analysis of these target analytes has led to an increase in testing and regulation, driven primarily by anionic polar pesticides such as glyphosate and glufosinate.

For cationic pesticides such as paraquat and diquat (quats) analytical method developments have lagged due to poor chromatographic resolution of the paraquat – diquat pair and often requiring high resolution accurate mass spectrometers.

This webinar will recap on polar pesticide analysis utilizing ion chromatography, including the inclusion of IC-MS/MS as an EURL-SRM, as well as introducing the New Thermo Scientific™ Dionex™ IonPac™ CS21 fast-4um column designed for the analysis of cationic pesticides (diquat, paraquat, clormequat, mepiquat, and others) in food, beverages, agricultural products, soil and environmental samples by IC-MS/MS or IC-HRAM-MS. No derivatization required. Join us for the second webinar in this series.
