The patented Sioutas Cascade Impactor separates and collects ultrafine, fine, and > 2.5-micron airborne particles (five size ranges including > 2.5, 1.0 to 2.5, 0.50 to 1.0, 0.25 to 0.50, and < 0.25 micron. Particles above each cut-point are collected on a 25-mm PTFE filter in each appropriate stage when the Sioutas Impactor is used with a 9 L/min sample pump. Particles less than the 0.25-micron cut-point of the last stage are collected on a 37-mm PTFE after-filter. The Sioutas Impactor is suitable for personal and area sampling indoors and may be used for ambient outdoor sampling with special provisions. Size-fractionated samples can be analyzed gravimetrically, chemically, and microscopically.
Features
