This European Standard specifies a high performance liquid chromatographic - UV detection (HPLC-UV) method for the simultaneous determination of two growth promoters Carbadox and Olaquindox contents in compound feeds and raw materials at levels ranging from the limit of quantification to 100 mg/kg.
The limit of quantification of the method has been demonstrated to be lower than 3 mg/kg for olaquindox and 4 mg/kg for carbadox.
