摘    要:建立了禽类产品中克球酚残留的液相色谱-电喷雾串联质谱(LC-ESI-MS/MS)检测方法。用甲醇对样品进行提取,提取液用正己烷萃取去油脂,然后用LC-18柱和阴离子交换柱净化,LC-ESI-MS/MS测定。利用基质校正曲线对克球酚准确定量。在2,5,10,20 μg/kg 4个添加水平下,克球酚的平均回收率稳定在55.38%~132.44%之间,日内精密度小于9.54%,日间精密度小于15.27%。在1~40 μg/kg范围内色谱峰面积与克球酚含量呈良好的线性关系,检出限为0.5 μg/kg,定量限为2.0 μg/kg。该方法选择性好,抗干扰能力强,可作为禽类产品中克球酚残留检测的确证方法。

关 键 词:固相萃取  基质效应  克球酚  禽类产品  液相色谱-电喷雾串联质谱联用

Abstract:A method is presented for the determination of clopidol residue in poultry products by liquid chromatography-electrospray ion trap tandem mass spectrometry(LC-ESI-MS/MS).Clopidol residue was extracted with methanol and cleaned-up by n-hexane from different poultry products.The extract was cleaned-up by an LC-18 column and an ion exchange solid phase extraction(SPE) column.Quantification was achieved by matrix calibration.The recoveries of clopidol in poultry products were in the range from 55.38% to 132.44%...
Keywords:liquid chromatography-electrospray ion trap tandem mass spectrometry (LC-ESI-MS/MS)  solid phase extraction (SPE)  clopidol  poultry products  matrix effect
