Stationary source emissions. Determination of the ratio of biomass (biogenic) and fossil-derived carbon dioxide. Radiocarbon sampling and determination Ingestion-build-264231 BS 1771-1 on wool and1 Scope This International Standard specifies sampling methods and analysis methods for the determination of the ratio of biomass and fossil derived carbon dioxide (CO2) in the CO2 from exhaust gases of stationary sources, based on the radiocarbon (14C isotope) method. The lower limit of application is a biogenic to total CO2 fraction of 0,02. The working range is a biogenic to total CO2 fraction of 0,02 to 1,0.
