Size distribution of the DEPM aerosol that was produced with the PALAS powder aerosol generator and analyzed using particle counters (optical GRIMM Aerosol counter and SMPS + C counter by GRIMM Aerosol). Particle counts were registered for one minute with the rotating steel brush at 1200 rpm and the piston at 30 mm/h. Data represents the mean of three independent experiments ± SEM. a) measurement of the nano-range from 250 nm to 2 μm performed on an optical particle counter by GRIMM Aerosol b) measurement of the nano-range from 5 nm to 300 nm performed on a Sequential Mobility Particle Sizer and Counter (SMPS + C) by GRIMM Aerosol
