Thermo Fisher Scientific Inc. is providing ion chromatography tandem mass spectrometry (IC-MS/MS) workflow solution for regulatory compliance with quaternary ammonium pesticides (Quats).
The new Thermo Scientific Dionex IonPac CS21-Fast-4m ion exchange column allows scientists to easily and accurately categorize and quantify the four cationic pesticides: diquat, paraquat, mepiquat, and chlormequat. These highly polar, permanent chemicals have long required, until now, complex workflows that are prone to quantitation errors. Food safety laboratories must ensure that these pesticides residues are found in or
The Dionex IonPac CS21 is a gold-standard column for Quat determination and quantitation, according to Alexander Semyonov, global product manager, ion chromatography mass spectrometry and Thermo Fisher Scientific. It has an advantage over other technologies in terms of matrix effects, which allows superior retention and separation of ionic species.
Thermo Fisher Scientific''s TSQ Altis Plus triple quadrupole mass spectrometer will provide a robust and comprehensive Quat analysis that fully meets regulatory requirements, while increasing laboratory productivity. Together, the system and new column can determine and quantify not only Quats, but also glyphosate and its metabolites.
