Determination of Clenbuterol in Meat Sample by Coupling Solid Phase Extraction with Gas Chromatography

Solid phase extraction and gas chromatography have been developed for the determination of the residues of clenbuterol in meat sample. The recoveries of clenbuterol in meat sample are 70%～80%; the detection limit is 1 μg/kg for meat samples. The ECD detection method was used for the detection of the clenbuterol derivatives. There is a good linear correlation(the calibration coefficient is above 0.999) between the peak areas and concentration of clenbuterol in the range from 0.005 μg/mL to 1.0 μg/mL.
