TN001900: Evaluation of Cationic Quaternary Amines by Ion Chromatography and Mass Spectroscopy (IC-MS)
Description
Pesticide contamination in food as a potential health risk is a growing public concern. The determinations of cationic quaternary amine polar pesticides are challenging due to their similar chemistries and similar masses and mass fragments. For example, Thermo Scientific Dionex™ IonPac™ CS21-Fast-4μm cation-exchange column was designed to resolve diquat and paraquat. This technical note provides the IC-MS conditions for twelve of the fifteen analytes. Three analytes, 1,2,4-triazole, difenzoquat, and propamocarb, are unsuitable using the Dionex IonPac CS21-Fast-4μm column for IC-MS analysis.| Market: | Food and Beverage |
