title: The identification of highly similar crude oils by infrared spectroscopy combined with pattern recognition method.
abstract: Based on attenuated total reflectance mid-infrared spectroscopy and moving window correlation coefficient method, a efficient analytical tool is presented for rapid identification of crude oil type. Spectra between highly similar crude oils can be easily distinguished by the spectral searching method. Compared with NIR, IR method can distinguish highly similar mixed crude oils given in the study. Parameters of the moving window correlation coefficient method are studied in the paper.
