LC/MS/MS Method Package for Residual Pesticide

On May 29, 2006, a positive list system that prohibits the sales of foods with any residual pesticides, feed additives and veterinary drugs in excess of fixed amounts was created. As a result, criteria for residues in foods and analytical methods were set for about 800 pesticides and veterinary drugs. This number is expected to increase further in the future. LC/MS/MS is often used for these analyses.

 

This method package is pre-registered with analysis conditions and compound information of target components for 167 residual pepticides for which residual standards and LC/MS analytical methods have been set in the positive list system. Analysis can now be started without performing difficult or time-consuming tasks required in LC/MS/MS analysis, such as evaluating the separation conditions and optimizing the MS parameters for each compound, to allow batch analysis of multiple components.

Analysis Example

MRM chromatogram of spinach extract spiked with 10 ppb of pesticide is shown below. 29 pesticide components were chosen from the MRM transition list text file in the method package, and analyzed in an ultrafast time of 3.5 minutes.
