| Abstract: | The calibration models of SARA(saturates,aromatics,resins and asphaltines) in residues have been established using attenuated total reflectance (ATR) Infrared spectroscopy combined with partial least squares (PLS). The results obtained by this method are agreement with those determined by elution-adsorption chromatography(EC). Compared with EC, this method is provided with advantages such as high-speed, simplicity, and good repeatability. |
