GC/MS Analysis of Quinoxaline—2—Carboxylic Acid Residues in Animal Muscle, Liver and Kidney Products

Abstract

Abstract: The developed GC-MS method provided a high sensitivity and specificity for the analysis of QCA (Quinoxatine- 2-Carboxylic Acid) in animal muscle, liver and kidney products. Less interferences and reproducible recoveries were obtained. The minimum detection limit for QCA was 1. 0μg/kg, which was defined on the basis of the current international maximum limit for carbadox and its metabolites residues in animal muscle, liver and kidney products. The recoveries for these samples ranged from 60%～125%. The correlation coefficient was 0.998.

Key words: GC-MS, metabolite, QCA, carbadox
