摘　　要：气相色谱与红外光谱联用技术既可以充分利用红外光谱长于定性和结构分析的优点,又可以应用气相色谱长于快速分离混合物的优点,对未知样品进行快速分析研究。对用常规红外无法表征的混合未知物中的各个组分,通过对混合物重建色谱图的积分、归一化还可以对各组分进行定量分析,其结果和气相色谱分析的结论能较好的匹配,但较单用气相色谱分析快速、简便。If the authors use normal infrared spectrometry, a lot of mixture compounds are difficult to characterize, because most of the peaks are overlapped in the spectra. Gas chromatography/ Infrared spectrometry (GC-IR) are widely used in the separation and identification of organic complexes. The GG-IR can characterize the ingredients quickly and correctly that are difficult to do for normal infrared spectrometry. The technique also can be used to quantitatively analyze the ingredients by integral. The authors studied an unknown complex by GG-IR here.
