We developed a new analysis method for the nine N-methyl carbamate pesticides in fruits and vegetables using ESI LC/MS/MS with direct sample injection into a short column. After extraction of the pesticides with ethyl acetate from sample, the extract is evaporated to dryness and redissolved in ultra pure water before injection into LC/MS/MS. The method needs no cleanup steps. The average recoveries...
We developed a new analysis method for the N-methyl carbamate pesticides in juice and wine. The juice and wine were diluted with ultra pure water, and determined by electrospray ionization tandem mass spectrometry (ESI LC/MS/MS) with direct sample injection into a short column. The new method, including sample preparation and determination, is simple and rapid, and allows simultaneous determination...
