摘要
文章探讨并建立了顶空气相色谱质谱外标法测定汽车内饰材料的易挥发性物质-苯系物的方法.在最优条件下获得了很好的柱效和分离度,各苯系物线性相关系数均在0.999以上,标准添加回收率在97.9 ％～101.5％之间,RSD在4.2 ％～6.9％之间.文章建立的检测方法及条件可以适用于准确地对汽车内饰材料中苯系物类VOC含量的测定.
In the paper, a method for the determination of volatile compounds benzene series in the automotive interior materials has been developed by headspace gas chromatography-mass spectrometry. Under the optimum conditions, the linear correlation coefficients of the benzene series were more than 0.999, and the standard addition recovery were between 97.9 %-101.5 % with RSD of 4.2 %-6.9 %. The utility of this method has been demonstrated by accurate determining the content of VOC in the automotive interior materials.
