| 摘 要： | 建立了一种ＬＣ－ＧＣ／ＦＴＩＲ联用方法。由于在联用系统中采用了峰容量大、分离效率高的ＬＣ－ＧＣ二维色谱技术，本法可明显提高ＧＣ／ＦＴＩＲ对复杂有机混合物中微量组分的检测能力。实验证明ＬＣ－ＧＣ／ＦＴＩＲ联用方法是复杂有机混合物分析的又一有效手段。

| Abstract: | A combined method of LC-GC/FTIR has been reported. The integration of LC-GC coupling into FTIR analysis allows to overcome problems of sensitivity encountered with capillary GC/FTIR detection. The applicability of the method is demonstrated by analysis of aromatics impurity in normal paraffin hydrocabons. The on-line LC-GC/FTIR is a reliable analytical technique for complex mixtures. |
