建立了乙酸乙酯提取、SCX小柱净化、GC-MS分析、外标法定量的猪肉样品中盐酸克伦特罗残留的检测方法。盐酸克伦特罗在10.24～512.0 ng/mL的范围内线性关系良好，相关系数r=0.9997。在1.92，5.12，12.80μg/kg添加水平下的回收率为73.0%～84.8%，测定结果的相对标准偏差为4.3%～8.2%（n=6）。2日间3浓度点的日间平均回收率在77.1%～81.2%之间，相对偏差在1.3%～5.3%之间。该方法简便、快速，精密度和准确度较好，能满足日常大批量猪肉样品中盐酸克伦特罗残留的检测要求。

Extracted with ethyl acetate, purified with SCX cartridge, quantified by external standard, a method was established for the determination of clenbuterol in pork by GC-MS. The good linearity was showed in the range of 10.24-512.0 ng/mL with the correlation coefficients r=0.999 7. The recovery rates were ranged from 73.0%to 84.8%at the spiked levels of 1.92, 5.12, 12.80μg/kg, with the relative standard deviations of 4.3%-8.2%(n=6). The average recovery rates of the 3 concentrations in the two different day were ranged of 77.1%-81.2%and the relative deviations were 1.3%-5.3%. The results indicated that the method was precise, accurate, easy, fast and suitable to complete the determination of clenbuterol residue in pork on daily work.
