摘　　要：建立了使用气相色谱-氢火焰离子检测器法同时检测溶剂型涂料中苯类物质和醚类物质的试验方法,主要针对甲苯、乙苯、醚类物质的提取和分离效果进行优化。样品按照国标18581,使用内标法,涂料经稀释、过滤后,进行检测。结果表明：苯类物质和醚类物质在检测限量值较低;样品的加标回收率为80%~105%,相对标准偏差小于5.0%,检出限为符合标准要求。The use of gas simultaneous detection of benzene substances and ether substances in solvent based coatings chromatography with hydrogen flame ionization detector was established, test method was mainly optimized according to the effect of extraction and separation of toluene, ethyl benzene, and ether compounds. According to GB 18581, using the internal standard, the samples were paint diluted, filtered, and detected. The results showed that benzene substances and ether compounds had good detection limits, the recovery rate of sample was 80% - 105% , the relative standard deviation was 5 %, the detection limits were able to fulfill the requirements of the standard.
