Scope

This standard specifies the method for determining the residual amounts of nitrofuran metabolites (3-amino-2-oxazolone, 5-morpholinomethyl-3-amino-2-oxazolone, 1-amino-isoxazole, and aminourea) in pet food by liquid chromatography-tandem mass spectrometry.
This standard is applicable to the determination of the residual amounts of nitrofuran metabolites (3-amino-2-oxazolone, 5-morpholinomethyl-3-amino-2-oxazolone, 1-amino-isoxazole, and aminourea) in pet food made primarily from animal-derived ingredients.
The detection limit of this standard is 0.25 μg/kg, and the quantification limit is 0.5 μg/kg.
