Figure 2From: A single-particle characterization of a mobile Versatile Aerosol Concentration Enrichment System for exposure studies Pre- and post-concentrator particle size distributions for characterisation studies A and B. Particle numbers are plotted as a function of geometric mean diameter for the size ranges (in μm): 0.2–0.5, 0.5–0.8, 0.8–1.1, 1.1–1.4, 1.4–1.7, 1.7–1.9, 1.9–2.3, 2.3–2.6, 2.6–2.9 and 2.9–3.2.Back to article page
