Abstract

The development of a discontinuous method for coulometric determination of elemental carbon (EC) in fine dust samples is reported. To separate organic carbon (OC) a combination of solvent extraction and thermal desorption at 500 °C in a N₂-atmosphere was applied. The detection limit of the method is 9 μg carbon, corresponding to 0.16 μg/m³ at a sampling volume of 55 m³. Applications of the method to the analysis of soot standards, diesel particles, and ambient samples are described. The overestimation of EC by removing OC only with thermal desorption varied from 10% (heavy traffic impact) to 48% (no traffic impact), the EC-overestimation by removing OC only with solvent extraction was 35% to 135%.
