Aerosol Characterization

Fragrance aerosol testing: particle size and chamber counts

The study compared the tested fragrance aerosols by spray particle-size distribution and time-resolved chamber counts under defined conditions.

Selected findingGroup-average D[4,3] was 31.49 µm for Test Article A and 75.03-89.77 µm for Comparator groups B-D.
