Laser-Raman spectroscopy technology was used for measuring and analyzing properties of oil products. Through comparing with the Raman shifts and relative Raman intensity ratios of the main fingerprint peaks, different kinds of oil products were identified successfully. Furthermore, the Raman spectra of the same type of petroleum products obtained from different private gas stations were measured and the petroleum qualities were detected. The favorable results were obtained in both oil identification and quality test. The present work provides a feasible method for quick, sensitive and nondestructive identification of oil products.
