Prediction of Gasoline Properties with NearInfrared Spectroscopy and Chemometrics

Near-infrared spectroscopy and chemometric data analysis techniques have been used to predict the chemical and physical properties of gasolines using a set of 359 commercial gasolines from 23 U.S. cities. These methods can estimate ten or more important fuel properties in a few minutes with reproducibilities equivalent to the lengthy ASTM standard procedures. Potential applications include field monitoring of gasolines and on-board sensors of fuel parameters.
