摘要
为研究白酒中的氨基甲酸乙酯,采用碱性硅藻土固相萃取+PSA填料过柱方式净化样品,使用气相色谱串联质谱外标法(Gc—Ms)定量测定白酒中氨基甲酸乙酯的含量。结果表明:在0.085mg/L到1.694mg/L浓度范围内线性相关系数r2为0.9973,线性良好,检出限为2μg/L,回收率在80%-90%之间,具有较好准确度,重复性实验RSD%为3.9,具有良好重现。
In order to analyze the ethyl carbamate in the Chinese liquor by headspace solid phase micro-extraction coupled with gas chromatography mass spectrometry detection (HS-SPME-GC-MS),. Result : Through the experiment, the linearity range of the method is from 0.085mg/L to 1.694mg/L, r2=0.9973, detection limit is 2 μ g/L, recovery is between 80%-90%, rsd%=3.9.
