Short summary
We describe a stepwise uncertainty analysis of 14C measurements of organic (OC) and elemental (EC) carbon fractions of aerosols. Using the Swiss_4S thermal-optical protocol with a newly established trapping setup, we show that we can efficiently isolate and trap each carbon fraction and perform 14C analysis of ultra-small OC and EC samples with high accuracy and low 14C blanks. Our study presents a first step towards the development of a common protocol for OC and EC 14C measurements.
