Flattening coefficients for liquid oleic acid droplets were determined for droplets containing varying concentrations of uranine when impacted on surfactant-treated glass slides. Flattening coefficients varied by surfactant and by uranine concentration. The results of this work suggest that interfacial forces between oleic acid droplets and surfactant-coated slides change with surfactant chemistry enough to have significant impacts on results from evaluation of size-selective aerosol sampler performance. The effects of uranine concentration and surfactant type should not be extrapolated from data generated using alternative surfactants when usingmicroscopy to verify the size ofmonodisperse liquid particles utilized for sampler performance testing.
