Size measurement analysis of PS microspheres standards using MDRS and FIM. The 10 μm (A) and 25 μm (B) microsphere standards were measured separately and, in a mixture (C). Particle sizes are obtained from 3 separate measurements (n = 3) reported as the mean ± standard deviation. Segmentation threshold (dark/light) were set for 12/12 in the FIM measurements.
