摘要
样品经均质后,用乙酸乙酯提取,正己烷脱脂,C18小柱净化,衍生后用GC ECD,NCI GC MS,NCI GC MSMS多种方法定性及定量测定,外标法定量。在0.1μg/kg水平,回收率为72%～110%,平行测定9次后相对标准偏差为16 5%。质量浓度在0～10μg/L范围内呈良好线性关系,相关系数r=0.9997。
<Abstrcat>A method for the determination of chloramphenicol (CAP) residues in seafoods for export was investigated. Multi-methods of GC/ECD? NCI-GC/MS? NCI-GC-MSMS were used to identify the target substance and to quantify the CAP residues. In the level of 0.1 μg/kg, the recovery is in the range of 72%～110%, and the relative standard deviation (n=9) is 16.5%. In the range of 0～10 μg/L, the concelation coefficient is 0.9997.
