The new sample preparation line for radiocarbon measurements on atmospheric aerosol at LABEC

► A new sample preparation line for 14C analysis on aerosol samples was set up at LABEC. ► Effective combustion, selection and collection of the CO2 were achieved. ► The efficiency of the line is consistent with 100%. ► AMS tests of samples: reproducibility better than 3‰; good background and accuracy.The line is designed to allow future 14C measurements on OC/EC.
