GB/T 23218-2008Determination of zeranol residues in animal original food - LC-MS-MS method (English PDF)

1 Scope

This standard specifies the foods of animal origin zeranol (zeranol), beta- zeranol (beta-zearalanol) and corn gibberellic oxazolidinone (Zearalanone) residues by high performance liquid chromatography - tandem mass spectrometry.

This standard applies to animal muscle, liver, fish, eggs and milk zeranol, beta- corn gibberellic alcohol corn gibberellic oxazolidinone Residues

Determination.

The standard method detection limit of 1µg/kg.
