Comparison of aerodynamic particle size profiles for the salmeterol treatments. SalD was tested at 70 L/min. TSHH was tested at 39 L/min. Individual points represent the pooled average of 12 capsules for TSHH and 9 actuations for SalD. Impactor-sized mass and fine particle mass results are overlapping data points. I/T/P inlet + throat + pre-separator, ISM impactor-sized mass, FPM fine particle mass <5 μm
