Abstract
A method based on time-resolved laser-induced fluorescence spectroscopy (TRLFS) for characterization and identification of different fossil diesel fuels, biodiesel and theirs blends is
introduced. The method uses a pulsed Nd:YAG laser with an excitation at 266nm and a single nanosecond pulse, measuring the dynamic response with a specific time gate width and gate step (time-resolved), and comparing them in terms of 3D-shapes, frequency behavior and decay behavior. The method also takes into account the maximal intensities and the wavelength of the maximal fluorescence intensity. With this information it is possible to differentiate quickly diesel fuels and is as well useful for in-situ-detection of the biogenic content in biodiesel blends.
