近年来国外有关气和色谱与傅里叶变换红外光谱联用(GC/FT-IR)的文献很多,而对其分离度的论述只有K.Krish-nan指出红外色谱图通过计算机编辑可以改善火焰离子色谱的分离度,但并未阐述两者分离度不同的原因所在。本文是在1983年工作的基础上,应用粗径SCOT玻璃毛细管GC/FT-IR分离鉴定己烯烃杂质,对色 In recent years, many foreign literature about gas chromatography and Fourier Transform Infrared Spectroscopy (GC / FT-IR), while the discussion of the degree of separation only K. Krish-nan pointed out that the infrared chromatogram through computer editing can improve the flame The separation of ion chromatography, but did not elaborate on the reasons for the different degrees of separation between the two. Based on the work in 1983, this paper uses the large diameter SCOT glass capillary GC / FT-IR separation and identification of hexene impurities, the color
