Abstract
In this study, successful discrimination between two types of gasoline of different octane number (90 and 95) was achieved. 24 samples of each type of gasoline were collected and analyzed with 1H NMR and processed with PCA and kNN. Uncovering adulterated gasoline 95 samples with gasoline 90 of different composition ratios of gasoline 90 (2.5, 5, 10, 20) % v/v have also been achieved by preparing 12 adulterated sample and applying the resulted 1H nuclear magnetic resonance (NMR) data to the original PCA model. The determination of adulteration composition was achieved using the 1H NMR spectra quantitatively through the least square linear regression analysis.
