摘要
研究以HP-5毛细管色谱柱,分流进样,气相色谱法测定溶剂型木器涂料中苯、甲苯、二甲苯含量的分析方法,确定了分析条件。该方法具有操作简单,准确,重现性好等优点,只须一次进样同时能测出涂料中苯、甲苯、二甲苯3种组分的含量,方法的加标回收率分别为98 1%~101 0%、97 9%~99 5%、98 0%~100 2%,线性相关系数为0 9993,0 9998和0 9992,相对偏差分别为0 78%、0 60%、0 68%。
A simple,rapid and accurate gas-chromatographic method for the determination of benzene,toluene and xylene was studied.The analysis was made by using HP-5 capillary column and FID detector.We could be gotten the contents of benzene,toluene and xylene by only one injection.All components and internal standard were separated in 185 mins.The results with good linearities(r=0999 3,0999 8 and 0999 2)were obtained.The coefficients of variation were 078%,060% and 068%.The recoveries of the method were 981%-1011%,979%-995% and 980%-1002%.
