Accelerator mass spectrometry for tracing fossil carbon content of combusted fuel Open
Fossil CO2 emission inventory from waste incineration plants needs to be determined for the purpose of emission trading in the future. A fundamental method for this is to measure the 14C content of the exhaust gas using accelerator mass sp…
