Fig. 2From: Effects of truck transportation and slaughtering on the occurrence of prednisolone and its metabolites in cow urine, liver, and adrenal glandsSelected ion chromatograms of the SRM transitions between the [M-H-(HCHO)]− precursor ion of prednisolone and the target (m/z 295) and qualifier fragment ions (m/z 280, 187). The chromatographic retention time of prednisolone is 16.43 minBack to article page
