摘要
采用顶空-气相色谱质谱联用法对烟用粘合剂中残留的苯系物(苯、甲苯、乙苯、二甲苯)进行分析,并讨论了各种条件对测定的影响。分析结果表明:该方法对4种残留苯系物的线性范围为1～100 mg/L,测定结果的相对标准偏差为2.5%～3.2%,样品的回收率为94%～102%。该方法可快速、准确测定烟用粘合剂中苯系物的含量。
A headspace gas chromatography-mass spectrometry（HS-GC/MS） method was applied to the determination of benzene compounds in cigarette adhesives and the effects of various analytical conditions were studied and optimized.The linear relationship were obtained in the ranges of 1～100 mg/L,the relative standard deviations（RSDs） were in the ranges of 2.5 %～3.2 % and the recoveries were from 94 %～102 %.The method was rapid,accurate and was suitable for the analysis of benzene compounds in cigarette adhesives.
