建立了准确测定烟用搭口胶热裂解产物中苯、甲苯和乙苯含量的气相色谱-质谱联用法，并考察裂解温度、样品水分、样品干燥温度、干燥时间等对定量结果的影响．结果表明，该方法在2～500μg/mL范围内线性良好，各苯系物的相关性系数值均在0．9900以上，检出限在0．378～0．996 ng/mL 之间，定量限在1．26～3．32 ng/mL之间，完全能满足样品中各苯系物含量的测定要求．所测定的几种搭口胶热裂解产物中苯、甲苯和乙苯的含量范围分别为138．7～188．4 mg/g，44．0～75．2 mg/g 和3．0～19．1 mg/g．

A method of gas chromatography mass spectrometry was established,which could accurately analysze the amount of benzene,toluene and ethyl benzene in the pyrolysis products of cigarette lap adhesive samples.The parameters of pyrolysis temperature,moisture,dryness temperature and dryness time were op-timized.The results showed that the linear possessed good in the range of 2 ~500 μg/mL,the linear correla-tion coefficients were above 0.990 0,the limits of detection were from 0.378 ng/mL to 0.996 ng/mL,the limits of quantification were from 1.26 ng/mL to 3.32 ng/mL.The method was suitable for determining the benzenes in cigarette lap adhesive samples.The determined concentration range of benzene was 138.7 ~188.4 mg/g,toluene was 44.0 ~75.2 mg/g and ethyl benzene was 3.0 ~19.1 mg/g in the pyrolysis products of cigarette lap adhesive samples.
