摘要：建立快速水蒸气蒸馏结合气相谱-热能分析仪技术测定肉制品和水产制品中13种N -亚硝胺化合物的方法。快速水蒸气蒸馏仪能以较高效率提取样品中亚硝胺类化合物，采用N -亚硝基二异丙胺作为内标可有效提高方法 稳定性和回收率。结果表明：在0~1.00μg/mL 质量浓度范围内，13种N -亚硝胺标准曲线线性良好，线性相关系数均
可达0.995以上，当取样量为200g ，浓缩体积为1.0mL 时，13种亚硝胺方法检出限为0.05μg/kg ~0.18μg/kg ，定量限为0.17μg/kg ~0.59μg/kg ，添加回收率为80.1%~112.9%，相对标准偏差为1.88%~7.16%。将该方法应用于16个实际样品检测，发现水产制品类样品中N -二甲基亚硝胺检出较多，部分样品含量超过国家限量标准，其他N-亚硝胺化合物偶有检出，含量相对较低。

of the method could be effectively improved by using N -nitrodiisopropylamine as internal standard.The results showed that the calibration curves had good linearity in the mass concentration range of 0-1.00μg/mL with the correlation coefficients greater than 0.995.When the sampling amount was 200g and the concentration volume was 1.0mL ，the detection limits of 13nitrosamines were 0.05μg/kg-0.18μg/kg ，the quantitative limits were 0.17μg/kg-0.59μg/kg ，the recoveries were 80.1%-112.9%，and the relative standard deviations were 1.88%-7.16%.This method was applied to the detection of 16real samples.It was found that N -dimethylnitrosamine was more detected in aquatic products ，some of the samples even exceeded the national limit standard ，and other N -nitrosamines were occasionally detected with relatively low content.Key words ：N -nitrosamines ；gas chromatography-thermal energy analysis ；rapid steam distillation ；meat prod -
