本实验采用顶空液相微萃取法,正辛醇作为萃取溶剂,样品在30℃水浴条件下搅拌顶空萃取25 min。待测物结合气相色谱分析方法,采用程序升温和分流进样,用氢火焰离子化检测器建立了测定指甲油中苯类物质的新方法。各种目标物的线性相关系数在0.983 3～0.993 4之间,加标回收率在95.88%～97.70%之间。该方法稳定可靠,分析结果良好。 In this experiment, headspace liquid phase microextraction, n-octanol as extraction solvent, the sample was stirred at 30 ℃ water bath for 25 min. The analytes were combined with gas chromatographic analysis, and programmed temperature and split injection were used to establish a new method for the determination of benzenes in nail polish using hydrogen flame ionization detector. The linear correlation coefficients of various targets ranged from 0.983 3 to 0.993 4, and the recoveries ranged from 95.88% to 97.70%. The method is stable and reliable, and the analysis result is good.
