TE-20-800X Eight Stage Non-Viable Andersen Cascade Impactor 220V SKU: TE-20-800X

The TE-20-800X is an eight-stage cascade impactor designed for aerodynamic particle size distribution analysis of airborne particulates. As air passes through the precision-machined aluminum stages with successively smaller orifice diameters, larger particles impact on collection plates while smaller particles remain in the airstream and cascade through each stage until they are captured.

Operating Principle

The Mark II Andersen cascade impactor separates particles by size using eight impaction stages organized serially in the airflow direction, with the largest particles impacting on the first stage and particles of successively decreasing size depositing on lower stages. Each stage contains precisely designed nozzles arranged radially from the stage center, which gradually accelerate airstreams to higher velocities as air flows through.

Performance Features

The design provides time-proven virtual elimination of particle bounce and re-entrainment, ensuring highest collection efficiency, reproducibility, and accuracy. The integrated PM10 high-capacity pre-impactor ensures accurate separation of large particles.

Applications

The eight-stage non-viable Andersen cascade impactor is widely used for testing aerodynamic particle size distribution (APSD) in pharmaceutical applications, environmental monitoring, industrial hygiene assessments, and aerosol research. Aerodynamic size measurements are critical for studies concerning lung inhalation, spray effectiveness, and air cleaning device performance.

By analyzing material deposited on individual stages and the final filter, critical parameters including fine particle fraction, fine particle dose, mass median aerodynamic diameter (MMAD), and geometric standard deviation (GSD) can be calculated.
