Foods of plant origin. Multiresidue methods for the determination of pesticide residues by GC or LC-MS/MS - Methods for extraction and clean-up Ingestion-build-258901 Public transport undertakings1 Scope This European Standard specifies methods for the extraction and clean up of food samples of plant origin for quantitative determination of pesticide residues. Different solvents can be used for this purpose. These pesticide residues are generally associated with other co extracted compounds which would interfere in the analysis. To purify the crude extracts to be analysed, several techniques can be used. This European Standard contains the
