A new LC/MS/MS method of analysis was developed for the common determination of about 100 polar pesticides in foodstuff. Different substances, belonging to the groups of carbamates, urea derivatives, acidics, organophosphates and triazoles, are handled using a unitary procedure of sample preparation. After extraction with methanol and clean up on a solid phase, the pesticides are analysed by LC/MS/MS and two different methods. The calibration was carried out with matrix standards, and the method was validated for different matrices. This quick, cost-effective multi-method is very sensitive and applicable for various vegetable matrices.
