Abstract:

Discs of a synthetic fiber medium, before and in two thicknesses after coating with finely divided particles of polystyrene-trimethylammonium iodide Triosyn-Registered resin, were challenged with an aerosol generated by atomizing an aqueous solution of ammonium fluorescein. A six-stage Andersen impactor was used to classify the particles penetrating each of these media and a fiberglass control medium. The coating on each stage was phased between water and methylene chloride to separate the fluorescein from the trapping medium. After application of a correction factor to correct for reaction with iodine, fluorescence of each extract was measured from which physical capture efficiency was calculated for particles within the submicron-to-low-micron range. Capture efficiencies of 97-99 were measured for 1.1-2.1 mm particles at 2 inches of water pressure drop.
