Fraction of highly (m/z = 44, mainly 
) and less oxygenated (m/z = 43, mainly C2H3O+) organics among the total organics, in particles detected during the reference period (black) and the laser-condensed particles, that is the difference of measurement with and without the laser (red), for (a) the main experiment and (b) when spraying water in a low RH atmosphere (b). The two black lines encompass the region where most atmospheric data are found to date31,32.
