2005-6-30FIG. 1 Schematic of an Andersen cascade impactor. Below the USP throat the different impaction stages consist of nole plates and impaction plates. The nole Set diameters decrease from top to bottom and the impaction plates act as obstacles and collectors for the aerosol. FIG.
A multi-stage multi-jet impactor for stack particulate effluents in moderate grain loading applications. Andersens impactor is made of stainless steel with Inconel O-rings and is able to withstand temperatures of 1500deg F if used without special collection substrate and back-up filter.
The impactor can be used with four six or eight stages with cut points ranging from 0.5 ..mu..m to 21 ..mu..m aerodynamic diameter.
The cascade impactor. The cascade impactor uses a momentum-based impaction mechanism to classify incoming aerosols into di erent sie bins. As the deposition of an aerosol in the lung is also driven by a momentum-based impaction in principle the cascade impactor is expected to be ideally suited for the task.
In this study the collection efficiency of a round-nole inertial impactor was enhanced through use of an additional punched impaction plate. The additional plate was installed between the nole outlet and the existing impaction plate. To determine its effect a simulation and an experiment were conducted. A parametric study was performed on a PM2.

Andersen Cascade Impactor Model. The Andersen cascade impactor consists of a USP metal inlet stages 0 to stage 7 and a filter stage for traditional use at 28.3 Lmin. The preseparator is the gateway to the eight collection stages and a filter stage .
Andersen Cascade Impactor ACI - copleyscientific.com. The Andersen Cascade Impactor ACI is arguably the most commonly used impactor within the pharmaceutical industry for the testing of inhaled products.
2014-10-30smaller particles are inertially impacted onto the collection plates. The submicrometer particles which are not collected by the last collection plate are caught in the backup filter which is an integral part of the impactor immediately downstream from Stage 7. Stage 0 is an orifice stage only.
6.1 Introduction Impactors are the official instruments for determining the particle sie distribution of aerosols generated from medical inhalers and nebuliers. They directly measure the aerodynamic particle sie which affects how particles move in an airstream.
