Fig. 5.

Stacked bar graphs of the number of aerosol particles produced per experimental condition (marked columns) during the total of n = 10 measurements (coloured layers) for each particle size (0.3 μm top left to 10 μm bottom right). Each layer corresponds with one block of ECs, the bottom layers were from Block A.1, the top layers Block B.5. Note that for reasons of visibility, the vertical axes are scaled differently for each particle size. (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.)
