傅立叶近红外光谱法测定汽油中苯含量

The Determmination of the Benzene in Gasoline by Fourier Near Infrared Spectrometry

介绍了傅立叶红外光谱测定汽油中苯含量的方法。以标准分析方法为参照,利用傅立叶红外光谱仪测定汽油的红外光谱,采用一阶微分和偏最小二乘法对汽油中的苯含量建立校正模型。该模型测定未知样品汽油苯含量的结果与标准分析方法的偏差符合标准方法的要求.

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.
