"In this work, we describe a rapid way to measure the size distribution of metal-containing particles from 10 nm to 20 µm, using a nano micro-orifice uniform-deposit impactor (nano-MOUDI) to collect particles that are then analyzed with a field portable X-ray fluorescence (FP-XRF) to determine metal composition and concentration."
