Paper Abstract

The infrared spectrum of either a pure material or a complex mixture is unique to that substance. However, the IR spectra of complex mixtures containing components of a similar nature, such as crude oils and gasolines, exhibit only small differences. It is often difficult to distinguish between these spectra, because of their similarities, when examining large sets of data in conventional ways. Principal component analysis (pca) has been applied to IR data obtained from a range of petroleum-related products.
