摘要
选用INNOWAX毛细管色谱柱 ,采用不分流进样模式 ,以气相色谱法测定对二乙基苯中的含氧化合物并用气相色谱 -质谱法鉴定。考察了色谱条件对对二乙基苯中几种含氧化合物分离效果的影响。含氧化合物测定结果的相对标准偏差为 3.36 %~ 4 .6 5 % ,加标回收率为 92 .3%~ 99.0 % ,检出限为 0 .0 2~ 0 .0 5mg/L。
Oxygenated-compounds in 1,4-diethylbenzene were determined by capillary gas chromatography, which were identified by gas chromatography-mass spectrometry. The sample was injected by splitless mode and analized with INNOWAX capillary column. The separation condition was optimized. The relative standard deviations are 3.36%~4.65%, the recoveries are 92.3%~ 99.0%. The detection limits are 0.02~0.05 mg/L.
