| titleOfInvention | Method for analyzing petroleum-based fuels and engine oils for biodiesel contamination |
| abstract | A method for detecting contamination of a conventional petroleum-based fuel used in an internal combustion engine is provided. A sample of engine oil is separated into a polar component and a non-polar component by a polar solvent. The polar component is analyzed for one or more biodiesel chemical components selected from the group consisting of plant sterols, fatty acid methyl esters, cetane, and combinations thereof, which relate to a degree of engine oil contamination. The polar and non-polar component may be analyzed by Gas Chromatography and Mass Spectrometry (GC/MS) and optionally Flame Ionization Detection (FID) for the one or more biodiesel chemical components, which can provide a semi-quantitative level of such biodiesel chemical components. Fuel samples can also be analyzed for biodiesel contamination species via GC/MS. |
