Sioutas Cascade Impactor
The patented † personal Sioutas Cascade Impactor consists of four impaction stages
and an aft er-fi lter that allows the separation and collection of airborne particles in
fi ve size ranges. The Sioutas Cascade Impactor is used with the Leland Legacy
®
Sample Pump (SKC Cat. No. 100-3002) or any other pump capable of maintaining
a constant fl ow rate of 9 L/min. Particles above each cut-point are collected on a
25-mm PTFE fi lter in the appropriate stage. Particles below the 0.25 μm cut-point
of the last stage are collected on a 37-mm PTFE aft er-fi lter. The Sioutas Cascade
Impactor clips onto a worker’s collar in the breathing zone and the pump clips onto
the worker’s belt. For area sampling, the impactor can be att ached to a tripod or
clipped in an appropriate location. The Sioutas Impactor may be used for ambient
outdoor sampling with special provisions (see Sampling on page 7). Size-fractionated
samples can be analyzed gravimetrically, chemically, and microscopically.
