| Abstract: | The sources of uncertainty in the determination of enrofloxacin residues in aquatic products by ultra-performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS)were analyzed.A mathematical model for uncertainty evaluation was established.The major uncertainty components were calculated and used to obtain the expanded uncertain?ties for the results of determination of enrofloxacin.The major uncertainty sources were determined as the preparation of standard solution,recovery of sample and measurement repeatability. |
