Validation of an Analytical Method for the Determination of Carbadox and Olaquindox in Feedingstuffs by Liquid Chromatography Coupled to UV and/or Diode Array Detector
The method performance characteristics of an analytical method based on high performance liquid chromatography (HPLC) for the detection of the banned growth promoters carbadox and olaquindox in feedingstuffs were assessed through a collaborative study. The relative standard deviation for repeatability (RSDr) ranged from 1.1 % to 5.5 % for carbadox and from 2.5 % to 6.2 % for olaquindox. The relative standard deviation for reproducibility (RSDR) varied between 6.4 % and 10.7 % for carbadox and between 12.8 % and 20.0 % for olaquindox. The HORRAT values were in all cases equal or below the critical value of 1.5. Therefore the method was considered suitable for the intended purpose.
