Tisch Environmental offers precision-machined aluminum impactors for ambient air sampling, from non-viable and viable cascade impactors to high-volume slotted impactors and personal samplers. Our impactors are engineered for reliable size-selective sampling for environmental, microbiological, and industrial hygiene applications.
Whether you need to fractionate particulate matter by size, collect biological aerosols, or perform high-volume sampling, our line of impactors gives you flexibility, accuracy, and durable performance.

Cascade impactors separate airborne particles by aerodynamic diameter. As air moves through successive orifice stages, larger particles are impacted onto collection substrates, while smaller particles remain in the air stream and continue through downstream stages. This method allows precise size fractionation of particles, which is important for health-based studies, chemical speciation, and regulatory compliance.
Depending on your sampling objectives, such as total mass, biologically active particles, respirable size fractions, or high-volume mass collection, Tisch Environmental offers impactor configurations that fit those needs.
Our technical team can help you choose the right impactor configuration based on your sampling program, target particle size range, and project goals.
