Note:Extracted ion chromatogram for the lowest level (0.1 ng/mL or 0.01 ng/g of shrimp tissue) of extracted standard of chloramphenicol (321.2/152; top) and internal standard (326/157; bottom). The impurity peak eluting at about 3.0 minutes is well-resolved from chloramphenicol and does not affect quantitation.
