顶空气相色谱法测定卷烟条和盒包装纸的苯系物

Determination of Benzene Homologues in Cigarette Carton and Packet Packing Papers by Headspace Gas Chromatography

建立卷烟条和盒包装纸中多种苯系物的测定方法。采用顶空气相色谱法测定卷烟条和盒包装纸中的苯、甲苯、乙苯、二甲苯。用建立的方法对某卷烟厂卷烟纸样品进行测定,平均加标回收率为91.4%~105.4%之间,相对标准偏差小于3%,最低检出限为0.005~0.02 mg/m2。所建立的方法简便、快捷,具有较好的精密度与更低的检出限,可用于烟草行业卷烟条和包装纸中的苯系物的测定。

A new method for determination of benzene homologues in cigarette carton and packet packing paper was established.Headspace gas chromatography was used to determine benzene,toluene,ethylbenzene,xylene.Cigarette packing paper samples from one tobacco factory were determined by this method.The recovery of these samples was 91.4%~105.4%,and the RSD was less than 3%,and detection limit was 0.005~0.02 mg/m2.The method was simple,rapid,and sensitive with lower detection limit.Therefore,it was suitable for determination of benzene homologues in cigarette carton and packet packing papers in tobacco industry.
