This International Standard specifies a high-performance liquid chromatographic (HPLC) method for the
determination of the carbadox content in premixtures and animal feeding stuffs.
The method is applicable to animal feeding stuffs with a mass fraction of carbadox of 0,5 mg/ kg (limit of
quantification) to 100 mg/ kg, and to premixtures with a mass fraction of carbadox up to 10 %.
The lower limit of detection is 0,1 mg/ kg.
NOTE 1 For animal feeding stuffs the mass fraction of carbadox is expressed in milligrams per kilogram, and for premixtures
as a percentage by mass.
NOTE 2 Carbadox is a chemotherapeuticum belonging to the quinoxaline group. Carbadox is used as a growth-promoting
feed additive for piglets.
