| 摘 要： | 本文采用气相色谱／傅里叶变换红外光谱（ＧＣ／ＦＴＩＲ）和气相色谱／质谱（ＧＣ／ＭＳ）方法联用，分析了某工作间的空气污染物。通过仔细调整ＧＣ／ＦＴＩＲ联用仪中ＧＣ和ＩＲ参数，使有机混合物得到了很好的分离。在未知物的鉴定中，以质谱法定性为主，红外光谱也发挥了特有的作用，使分析结果更加可靠。

| Abstract: | In this paper, the air pollutants were analyzed with a combination of Gas chromatography/Fourier transform infrared spectroscopy (GC/FTIR) and Gas chromatography/Mass spectroscopy (GC/MS). The organic mixture was well separated after a careful adjustment of GC and IR parameters in GC/FTIR. In the identification of unknown components, MS is a main method, while IR is also useful to confirm the results. |
