Principle 3
Clenbuterol residues in honey with sodium acetate buffer solution (pH = 5.0) extracted, filtered, dried OasisHLB1) or equivalent solid phase
Extraction column, eluted with a solution of ammonia and methanol evaporated and the residue was dissolved in methanol and 0.1% formic acid solution, over 0.2μm membrane, the sample solution
For liquid chromatography - tandem mass spectrometer, internal standard.
4 Reagents and materials
