Method for the determination of α-trenbolone, β-trenbolone residues in bovine muscle, liver and kidney - LC-UV method and LC-MS-MS method 1 Scope This standard specifies the LC-UV method and LC-MS-MS method for the determination of α-trenbolone, β-trenbolone residues in bovine muscle, liver and kidney. This standard is applicable to the determination of α-trenbolone, β-trenbolone residues in bovine muscle, liver and kidney. For the method detection limit of this standard: the detection limits of LC-UV method and LC-MS-MS method for the determination of α-trenbolone, β-trenbolone are both 2μg/kg. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this standard.
