Instead of the standard SN/T 1924-2007 "Importers clenbuterol in food of animal origin, Lecco dopamine, salbutamol, terbutaline Detection of Residual liquid chromatography - mass spectrometry/mass spectrometry. " This standard compared with SN/T 1924-2007, the main technical changes are as follows. --- Increasing the scope of food of animal origin fine bone soup, milk and milk powder; --- Sample before adding n-hexane degreasing step; --- By a C18 solid phase extraction column and cation exchange column changed to mixed cation exchange column; --- Sample liquid solvent consisting of aqueous acetonitrile (19) is amended as 0.1% formic acid; --- Clenbuterol ion monitoring by the 277.3/203.0,277.3/modify 277.0 259.2/203.0,277.0/132.0, 277.0/168.0; --- The experiments prove that the lower limit of the measurement Clenbuterol 0.5μg/kg revised to 0.05μg/kg. This standard is proposed and managed by the National Certification and Accreditation Administration Committee. This standard was drafted.
