Cascade Impactors

TSI’s cascade impactors effectively collect particles with aerodynamic diameters ranging from 10 nm to 10 µm, in 3 to 13 size fractions, and at flow rates of 2, 10, 30, or 100 L/min. The number of stages influences the size resolution and detail of the quantitative analysis. The MOUDI II impactors feature rotating stages, which ensure a more uniform particle deposition across the impaction surface. This design increases particle mass collection, minimizes bounce and re-entrainment, and enhances the accuracy of quantitative analysis. The high-flow impactors (HFI) are designed for efficient sampling of particles in pristine environments with low concentrations.
