| Anmerkungen | The aim of the method ring test is - a real-world assessment of the uncertainty of sampling from the fruit crate to the analytical sample in accordance with the Eurachem guidelines, - the evaluation of the performance of the labs with respect to the homogenisation of the samples, and - the evaluation of the analytical performance of the labs with respect to the quantification incurred residues of typical pesticides in grapes. Whole fresh grapes with incurred residues as well as a homogenate, prepared of the same grapes, are provided. PROOF-ACS, as the organiser, carries out a standardised practical sampling of the laboratory samples from the fruit crates. The laboratory samples are provided to the participants, two samples for each lab. In addition, a homogenate, prepared of a sample of all fruit crates is provided to derive the analytical uncertainty for the respective pesticides and the participating laboratories. The participants are requested to - homogenise the samples in accordance with a guideline provided by PROOF-ACS, and to provide a photo documentation of the process of the homogenisation. - analyse all 4 sub-samples, 2 for each non-homogenised material for pesticide residues (multi-residue methods). - analyse the homogenate as provided by PROOF for pesticide residues (multi-residue methods). | |||||||||||||||
