| Abstract: | The paper introduces the benzene in gasoline by Fourier infrared spectrometric test method ,it references standard test method, it uses Fourier infrared spectrum analyzer to determine infrared spectrum of gasoline ,and establish calibration model of the benzene in gasoline , by adopting first order differential and partial least square method, the benzenne in gasoline result deviation between the calibration model and standard test method is less than the requirement of standard test method. |
