摘要：

The usefulness of cryotrapping gas chromatography-Fourier transform infrared spectrometry for the analysis of the repartitioning agents clenbuterol, mabuterol and salbutamol in cattle has been evaluated. It is demonstrated that the technique is able to detect and identify the trimethylsilyl derivatives of these compounds in samples extracted from urine and liver of veal calves and cattle with a detection limit of 1 ng on column, equivalent to 2.5 mug l-1 or mug kg-1 of the original sample. It is anticipated to become a valuable method for confirmation in residue analysis, in addition to e.g. gas chromatography-mass spectrometry.
