Abstract: Mineral oil, edible oil, gasoline or petroleum samples were dissolved in CCl4. A portion (300 ml) of the resulting solution was injected into a carrier stream of CCl4 at a flow rate of 1.5 ml/min. The area under the FTIR absorbance spectrum from 3058-2780 cm-1, corrected for a baseline established between 3200 and 2700 cm-1, was used for quantification. The detection limit was 0.6-1.1 mg/ml oils and greases; RSD was 1.4-4.1% (n=10). The throughput was 60 samples/h. The method was also applied to aqueous solutions containing different types of oils, after microwave-assisted extraction of the oil into CCl4 by irradiation at 420 W for 6 min. Results are presented and discussed.
