DIN-Fachbericht CEN/TR 15591:2007-04

This Technical Report gives an overview of the suitability of 14C-based methods for the determination of the fraction of biomass carbon in solid recovered fuels, using detection by scintillation, gas ionization and mass spectrometry. The principle of the 14C method is to determine the biomass content by total carbon by measuring the amount of 14C present in the sample. The biomass content by total carbon of a material is calculated as the proportion of the isotope abundance of 14C in that material and the isotope abundance of 14C in the atmosphere at the time when the biomass was laid down.
