Dispersibility Analysis Toolkit

Quantifying aerosol dispersibility using the Wasserstein distance

Standard aerosol characterization collapses rich particle size distribution data into summary statistics that obscure clinically relevant variability. This toolkit implements a distribution-sensitive analytical framework based on the Wasserstein distance (Earth Mover's Distance) to quantify how closely an inhaler-generated aerosol approaches a powder's intrinsic dispersion limit. The metric is formulation-agnostic, physically interpretable, and works with standard laser diffraction data.
