The Fast Screening Andersen (FSA) is an AIM version of the standard Andersen Cascade Impactor (ACI) suitably modified to provide a reduced stack plus filter (F) suitable for either:
Quality Control (FSA-QC) – Stages 0 (or -1, or -2A) and F are used in conjunction with a Stage X, having a cut-off diameter as close as possible to the Mass Median Aerodynamic Diameter (MMAD) of the aerosol, as determined during full resolution cascade impactor testing.
Product Development (FSA-HRT) – stages with cut-off diameters are available at 5.0 and 1.0 μm for MDI applications at 28.3 L/min. Also, for this flow rate and higher flow rates (60 and 90 L/min) stages having traditional ACI cut-points of 4.7 and 1.1 μm are available primarily for DPI applications
