| 摘 要： | 建立了热脱附／毛细管气相色谱／质谱联用测定车内空气中苯、甲苯、乙酸丁酯、乙苯、对／间二甲苯、苯乙烯、邻二甲苯、十一烷和对二氯苯等挥发性有机物采样、分析方法。十种挥发性有机物在一定浓度范围内工作曲线线性良好，相关系数均在0．9970～0．9998之间。检出限在0．2～1．2μg/m^3。用该法检测了某汽车企业生产的轿车内的空气，取得满意结果，表明本方法具有一定的实用性、推广性。

| Abstract: | A method has been developed for the confirmation and quantitation of ten VOCs including benzene, toluene, butyl acetate, ethylbenzene, m/p - xylene, styrene, o - xylene1,4 - dichlorobenzene, undecane. This method extract VOCs from in - car air using Tenax - TA Adsorbent Cartridge. The concentration of VOCs is determined using thermal Jesorption by gas chromatography/mass spectrometry （GC/MS）. The limit of detection （LOD） was 0. 2 - 1.2μg/m^3. The optimized method has been -sncessfully applied to the analysis of field samples from in -car air. |
