摘要
目的：建立毛细管气相色谱法同时测定油墨中的苯、甲苯、对二甲苯、间二甲苯和邻二甲苯的检测方法。方法：用正己烷提取油墨中的上述5种苯系物，毛细管色谱柱（HP—Innowax）分离，FID检测。结果：该方法分离效果好，检出限均低于0．5mg／g，回收率在89．4％～102．1％之间，精密度为7．7％～13．8％。结论：该方法快速，灵敏，准确，完全满足油墨中上述5种苯系物的测定要求。
Objective： A method using gas chromatography was established for analysis of five benzenes In printing ink. Methods： The Five benzenes were extracted with n - hexane, separated with capillary column HP - Innowax and detected by FID. Results：The Five benzenes were completely separated. The detection limits were less than 0. 5 mg/g, the recovery rate 89.4% - 102. 1% and the RSD 7.7% - 13.8%. Conclusion：The method is rapid ,sensitive and accurate and can be used for determination of the five benzenes in printing ink.
