INFLUENCE OF ELECTROSTATIC CHARGE UPON THE DEPOSITION BEHAVIOR OF PHARMACEUTICAL AEROSOLS WITHIN CASCADE IMPACTORS
Cascade impactors, routinely used for in vitro particle size characterization of pharmaceutical aerosols, are calibrated using dilute, charge-neutralized, monodisperse aerosols. But pharmaceutical aerosols are known to generate concentrated, inherently charged, polydisperse aerosol clouds. A …

Investigation of Machinability and Dust Emissions in Edge Trimming of Laminated Carbon Fiber Composites
… materials. Data was initially collected using cascade impactors where mass median aerodynamic diameter (MMAD) was found to be .12 µm - .35 µm when machining at 0o to 135o of fiber direction without using local exhaust ventilation. Real-time particle analysis instruments were introduced into the …
