  "text": "A collaborative study was arranged in which 5 samples were analysed by 11 laboratories. These samples consisted of two premixtures; one was mixed with an organic matrix (O 100) and the other with an inorganic matrix (A 100). The theoretical content is 100 mg diclazuril per kg. The three mixed feeds for poultry were made by 3 different producers (NL) (L1/Z1/K1). The theoretical content is 1 mg diclazuril per kg. The laboratories were instructed to analyse each of the samples once or in duplicate. (More detailed information on this collaborative study can be found in the Journal of AOAC International, Volume 77, No 6, 1994, p. 1359-1361). The results are given in the following table.\nSample 1A 100\nSample 2O 100\nSample 3L1\nSample 4Z1\nSample 5K1\nL\n11\n11\n11\n11\n6\nn\n19\n18\n19\n19\n12\nMean\n100,8\n103,5\n0,89\n1,15\n0,89\nSr (mg/kg)\n5,88\n7,64\n0,15\n0,02\n0,03\nCVr (%)\n5,83\n7,38\n17,32\n1,92\n3,34\nSR (mg/kg)\n7,59\n7,64\n0,17\n0,11\n0,12\nCVR (%)\n7,53\n7,38\n18,61\n9,67\n13,65\nNominal content (mg/kg)\n100\n100\n1\n1\n1\nLnumber of laboratories\nnnumber of single values\nSr standard deviation of repeatability\nCVr coefficient of variation of repeatability\nSR standard deviation of reproducibility\nCVR coefficient of variation of reproducibility",
