DIN EN 17049:2018-05

This European Standard specifies a high performance liquid chromatography - mass spectrometry (LC-MS/MS) method for the identification of tylosin, spiramycin, virginiamycin, carbadox and olaquindox in animal feeds. The method is suitable for the identification of low concentrations of tylosin, spiramycin, virginiamycin, carbadox and olaquindox in compound animal feeds. A limit of identification of 1 mg/kg for tylosin, spiramycin and virginiamycin, 4 mg/kg for carbadox and 3 mg/kg for olaquindox should be obtained by using the described method. The method was fully validated during a collaborative study.
