| Abstract: | The rapid determination of the contents of aromatic and olefin in motor gasoline was established by Nicolet 6700 mid-infrared spectrometric analyzer.The calibration models of aromatics and olefins were established by TQ analyst EZ edition（Nicolet） analysis software,with the results of 95 motor gasoline samples as reference by multi-dimensional gas chromatography（MGC）.The correlation coefficients of calibration models for aromatics and olefins were 0.9896 and 0.9841,respectively.The accuracy of mid-infrared spectroscopy（MIR） method was validated by comparing with the MGC method and national standard fluorescence indicator absorption（FIA）.The MIR method has faster,repeatable,and less expensive advantage. |
