2017 American Association for Aerosol Research. Two nozzles, modified and original, were tested in a sampler that was placed in a wind tunnel and penetration efficiencies, Stk50, and slope of the performance curve were determined by challenging the sampler with fluorescent-tagged monodisperse test aerosol particles having known concentration. It was shown that a change in convergence angle of the modified nozzle can affect impactor performance. The Stk50 for original and modified nozzles were 0.57 and 0.49, respectively. The slope of the efficiency curve for original and modified nozzles was 1.52 and 1.36, respectively. 2017 American Association for Aerosol Research.
