| 摘 要： | 用乙酸乙酯稀释溶剂型涂料样品，在较低的汽化温度下直接进样，溶剂型涂料中未汽化的组分留在汽化室里，而苯、甲苯和二甲苯汽化后进入毛细管，用气相色谱法氢火焰离子化检测器进行检测，与国家标准分析方法进行比较，该法具有操作简单、精密度高等优点。

| Abstract: | After being diluted with ethyl acetate,the solvent paint samples were directly injected at lower vaporization temperature.The substance which had not been vapored were left in vaporizing chamber,and benzene,toluene and xylene went through capillary to be detected by FID.Compared with GB method,this method was simple and precise. |
