Precision and accuracy in the analysis of standard solutions

This proficiency test will give eligible laboratories (NRLs, OCLs, a selection of laboratories from third countries) the opportunity to crosscheck the standard solutions they apply in their daily routine by analysing standard mixes provided by the EURL Berlin. Each participants will receive three different standard mixes containing an unknown quantity of minimum required and recommended analytes of avermectins, coccidiostats and NSAIDs (one substance group per mix). The EURL classification for these residues can be found here: https://eurl-residues.eu/eurl-bvl/bvl-analytical-methods/nrcp-substance-list/

The preliminary report is now available. Participants are asked to submit their comments by 15 January, 2024.
