  • Intercomparison study of two multi-residue methods for the enforcement of EU MRLs for pesticides in fruit, vegetables and grain: Phase I: Intercomparison study of pesticide solutions


Phase I of this intercomparison study was designed to test the ability of participants to prepare calibrants with acceptable accuracy, and also to perform the subsequent measurements on a series of test solutions with acceptable precision and accuracy. Stability and homogeneity studies of dilute solutions of 27 pesticides are described. Solutions of the individual pesticides were prepared in ethyl acetate and mixed to produce a series of 6 test solutions. Ampoules of the 6 test solutions were distributed to 25 expert laboratories in 15 European countries together with a detailed analytical protocol and a set reporting sheets. All 25 participant laboratories returned results and, for the majority of pesticides, the agreement was excellent.
