Particle sizes of dry powder formulations.

Sample Name Diameter (µm) Span (µm)
Dv10 Dv50 Dv90
PMB–SD 1.2 ± 0.1 2.7 ± 0.1 5.7 ± 0.3 1.6 ± 0.1
CIP–SD 0.7 ± 0.1 2.6 ± 0.2 6.4 ± 0.3 2.2 ± 0.1
PMB–CIP SD 0.7 ± 0.1 2.7 ± 0.1 6.3 ± 0.1 2.0 ± 0.1

Dv10, Dv50, and Dv90 are volumetric diameters at 10%, 50% and 90% cumulative numbers, respectively. Data shown are representative of triplicate tests (mean ± SD, n = 3).
