Chromatograms of BMZs in chicken, chicken blood, and chicken liver samples. (a) the standard solution at 1.0 mg/L, (b) a sample solution extracted by G-Fe₃O₄ MSPE, and (c) 0.8 ng/g of the spiked sample solution extracted by G-Fe₃O₄ MSPE. The peaks corresponded to the following BMZs: 1. OXF, 2. MEB, 3. FLU, 4. ALB, and 5. FEN.
