建立了固相微萃取与气相色谱-质谱联用测定肉中克伦特罗的方法。在一定线性范围内，本方法相关系数0．9993，回收率96％-104％，检出限0．48-μg/kg，相对标准偏差7．1％。方法快速、准确，具有良好的实际应用价值。

A method was developed for the determination of clenbuterol in meat using solid phase microextraction （SPME） coupled with gas chromatography-mass spectrometry （GC-MS）. The linear correlation coefficient of the GC-MS method was 0.999 3, and the detection limit was 0.48 μg/kg. The average recoveries at three spiked levels varied from 96% to 104%, and the precision expressed as relative standard deviation for three replicate determinations was 7.1%. This method proved to be simple to use, accurate and reliable and have potential for practical application.
