Fig. 6: Results of aerodynamic analysis.

The recovery of active pharmaceutical ingredient (API) in % plus mean value as black line on the left vertical axis and the fine particle fraction below 5 μm (FPF) in % plus mean value as black line on the right vertical axis, data for the recovery is shown in violet dots with dashed lines as the upper (110%) and lower (90%) limits for the recovery, data for the FPF is shown as orange bars, n = 3, error bars = standard deviation.
