Sioutas Cascade Impactor

Sioutas Cascade Impactor
The patented† personal-size Sioutas* Cascade Impactor separates and collects airborne particles in five size ranges: > 2.5 µm, 1.0 to 2.5 µm, 0.50 to 1.0 µm, 0.25 to 0.50 µm, and < 0.25 µm. When used with PTFE collection filters, the Sioutas Impactor is highly efficient at collecting particles without the use of impaction grease or substrate coatings and at retaining unstable compounds for size-fractionated chemical analysis.
† U.S. Patent No. 6,786,105 
* Developed by Dr. Constantinos Sioutas of the University of Southern California in partnership with the Mickey Leland National Urban Air Toxics Research Center (NUATRC). See reference below. 
* Requires special provisions, see operating instructions.

Sioutas Impactor and Leland Legacy Pump Are Powerful Partners 
The Sioutas Impactor and SKC Leland Legacy Sample Pump operated at 9 L/min are powerful partners that ensure precise particle separation at the specified cut-points and sample collection on the filters at each stage. The Sioutas Impactor is simply clipped to a worker's collar or lapel for personal sampling and is also suitable for area sampling.
