摘　　要：采用顶空进样气相色谱法对溶剂型木器涂料中的苯系物进行分析,所使用的方法能较好地避免基质的干扰。在给定的浓度范围内,各目标组分呈现良好的线性相关,检测限与定量限也都在国家规定的最大限量之下,回收率在85.6%～105%之间,日内精密度<7.2%,日间精密度<9.6%。This new headspace-GC method can be used to analyze benzene, toluene and xylene in the adhesives without interference of the matrix. With this method the relation of the peak area and concentration was hnear for all the components in the given concentration range. The LOD and LOQ were within the range required by the national standards. The average recoveries varied from 82.2% to 105.3%. The intraday precision was less than 4.5% while the interday precision was less than 6.4%.
