Aerosols in the atmosphere occur in a wide range of sizes, and smaller particles can penetrate deeper into the human respiratory system. Particulate matter (PM) fractions (especially PM_2.5 and PM₁₀) are regulated to prevent adverse health effects. The Fidas® Frog (Palas, DE) is an optical aerosol spectrometer that determines particle size using Lorenz–Mie scattered light analysis of individual particles. It simultaneously measures environmentally relevant mass fractions (PM₁, PM_2.5, PM₄, PM₁₀, and TSP, as well as the particle number and the particle size distribution within the particle size range of 0.18 – 93 µm.
