摘要
建立隔膜中醇酯十二残留量的顶空-气相检测方法,色谱柱为HP-5毛细管柱,载气为高纯氮气,检测器为氢火焰离子化检测器(FID),采用外标法定量。在试验的范围内,其峰面积和含量具有良好的线性关系,建立面积-含量曲线方程为y=2.4E+06x-11036,相关系数为0.999。本分析方法的灵敏度高、专属性强、重现性好。
To establish a method for determination of alcohol ester twelve residues in the diaphragm, use headspace GC with the column of HP-5, FID as detector and nitrogen as the carriergas to carry out the experiment. Peak area and concentration presents good linearity in exp-rimental range, area concentration curve equation is y=2.4E＋6X-11036,the correlation coefficient is more than 0.999.The method has good specificity, repeatability and high sen sitivity.
