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.

Facilities

Data Center Particle Deposition: Surface Contamination

The client needed a measured baseline for surface particle accumulation across operating spaces, with enough spatial detail to compare buildings, halls, and sampling heights.

Selected findingAcross 123 primary slides, mean and median mass deposition rates were 14.7 and 7.5 mg/m²/day.
