Abstract A high-flow (10 L/min) nanoparticle respiratory deposition (NRD) sampler was
designed and evaluated to achieve reduced limits of quantification (LOQs) for metal
nanoparticles. The high-flow NRD consists of an inlet, impactor stage, diffusion stage, and a
final filter. An impactor stage with 12 nozzles was designed from theory to achieve a cut-off
diameter of 300 nm at 50% particle collection efficiency (d 50). Various depths of 37-mm-
diameter polyurethane foam cylinders were tested for the diffusion stage to obtain a …
