Dionex is pleased to announce an improved method for the determination of carbamates in rice, potato, and corn (maize) as specified in AOAC Method 2007.01 and European Union standard EN 15662, 2008. Application Note 272: Faster Yet Sensitive Determination of N-Methylcarbamates in Rice, Potato, and Corn by HPLC demonstrates accurate results using this new application on an UltiMate® 3000 high-performance liquid chromatography (HPLC) system with an Acclaim® Carbamate column and detection performed using an FLD-3400RS fluorescence detector.

The N-methylcarbamates and the N-methylcarbamoximes are among the most widely used pesticides in agriculture. Because these pesticides may create health problems-including issues impacting the central nervous and reproductive systems-concerns over the presence of carbamate residues in water, crops, and food products have promoted increased awareness and testing for these compounds. This application provides detection in crops of the same pesticides specified in U.S. EPA guidelines for monitoring the presence of carbamate pesticides and related compounds in raw surface water using EPA Method 531.2.
