M03.002 Determination of pesticides in food by LC-MS/MS

For the preparation of aqueous and solid samples QuEChERS method is used. Therefore, samples are homogenised by means of dry ice, extracted with acetonitrile and cleaned up by dispersive solid phase extraction. The final acidified extract can be analysed directly by LC-MSMS. The concentration of pesticides in samples is quantified with an external calibration and results are reported in mg/l or mg/kg.
