Thermo Fisher Scientific Inc. is developing a new innovative ion chromatography tandem mass spectrometry (IC-MS/MS) workflow solution for regulatory compliance and cost-effective and reliable analysis of quaternary ammonium pesticides (Quats).
The new Thermo Scientific Dionex IonPac CS21-Fast-4m ion exchange column enables scientists to easily and accurately identify and quantify the four cationic pesticides: diquat, paraquat, mepiquat, and chlormequat. These highly polar, permanently charged chemicals have often been difficult to analyze, and have, until now, required complex workflows that are prone to quantitation errors. Food safety laboratories must accurately determine the residue levels
According to Alexander Semyonov, the global product manager, ion chromatography mass spectrometry and Thermo Fisher Scientific, the Dionex IonPac CS21 is the gold-standard column for use in your Quat determination and quantitation workflow. It also allows for longer matrix effects, and for superior retention and separation of ionic species.
Thermo Fisher Scientific''s TSQ Altis Plus triple quadrupole mass spectrometer will provide maximum coverage for all polar, highly polar, ionic, and ionizable food contaminants in one IC-MS/MS system. Together, the system and its new column can identify and quantify not only Quats, but also glyphosate and its metabolites.
