Determination of biogenic component in solids and liquids by the radiocarbon (14C) method

Biogenic component in solid and liquids can be determined by the 14C method - the biogenic component has the 14C activity of the contemporary atmosphere, while fossil component does not cantain any 14C. For liquid fuels iz is possible to apply also the direct method by measuring 14C activity by liquid scintillation counters. However, the direct LSC method has some limitations of applicability. Here we discuss the applicability of the direct LSC method for coloured liquid fuels, and also compare the direct LSC with the AMS method.
