%X A method for the separation and determination of nitrogen compounds in catalytic gasolines by gas chromatography-nitrogen chemiluminescence detection (GC-NCD) was established. The effects of the flow rate of carrier gas and the oven temperature on the resolution were studied. More than 20 nitrogen compounds, including amines, pyridine, aniline, 2-methyl aniline, 3-methyl aniline, 4-methyl aniline, quinoline, and indole, in catalytic gasoline were identified based on the retention time of some pure nitrogen compounds and by gas chromatography-mass spectrometry. The relative standard deviations of the peak areas of main nitrogen compounds in a catalytic gasoline sample were less than 2.5% and the detection limits for nitrogen were 1.0 mg/L under the chosen conditions. The linear ranges were 1.0~100 mg/L nitrogen for each nitrogen compound. The correlation coefficients were more than 0.998. The method can be successfully applied for the determination of each nitrogen compound in different catalytic gasolines.
