Cascade Impactors

TSI’s cascade impactors provide precise size-segregated particle collection for aerodynamic diameters ranging from 10 nm to 10 µm. Available in configurations with 3 to 13 stages and flow rates of 2, 10, 30, or 100 L/min, these impactors enable detailed particle size distribution analysis. The number of stages directly influences size resolution, ensuring high-quality data for quantitative analysis.

The MOUDI™ (Micro Orifice Uniform Deposit Impactor) II impactors feature rotating stages, enhancing sample uniformity by minimizing particle bounce and re-entrainment. This innovative design maximizes particle mass collection and improves the accuracy of subsequent analysis, making them ideal for critical research and industrial applications.
