DIFFERENTIATION BETWEEN FOSSIL AND BIOFUELS BY LIQUID SCINTILLATION BETA SPECTROMETRY - DIRECT METHODRonald Edler1, Lauri Kaihola2 1 PerkinElmer LAS (Germany) GmbH, Ferdinand-Porsche-Ring 17, 63110 Rodgau, Germany 2 PerkinElmer Low Level Laboratory, Wallac Oy, P. O. Box 10, 20101 Turku, Finland Liquid scintillation spectrometry of 14C in gasoline/ethanol and diesel oil was carried out using Quantulus® and straight mixtures of fuel and an organic scintillation cocktail. A linear correlation was found between the concentration of carbon that originates from the bioethanol (biocarbon) and the fuel mixture’s 14C activity in the range 0–100% (m/m) bioethanol content. Because of these good linear correlations, quantitative determination of a fuel’s biocarbon content can be made by 14C analysis. The direct method is also applicable to analysis of the bio-based materials dissolvable in solvents, which can be mixed with scintillation cocktails. Close X |
