Scope
This standard specifies the method for the determination of α-trenbolone, β-trenbolone, 19-ethylene norgusterone and epi-19-ethylene nortestosterone residues in milk and milk powder by high performance liquid chromatography-tandem mass spectrometry. This standard applies to the determination and verification of α-trenbolone, β-trenbolone, 19-ethylene nortestosterone and epi-19-ethylene nortestosterone residues in milk and milk powder. The detection limit of this standard method: α-trenbolone, β-trenbolone, 19-ethylene nortestosterone and epi-19-ethylene nortestosterone in milk are 1 μg/kg, and α-trenbolone, β-trenbolone, β-trenbolone, 19-ethylene nortestosterone and epi-19-ethylene nortestosterone were 5 μg/kg.
