Abstract : The effect of a high concentration of ionized air molecules on sampling submicron T1 phage aerosols of a submicron particle size was evaluated by comparing the phage recoveries of all-glass impingers (AGI-4) and Type 6 filter papers. Sampler recoveries of all ionized aerosols were less than the recoveries of non-ionized control aerosols. These reductions in recovery were greater with positive ions than with negative ions or ions of mixed polarity. The AGI-4 allowed considerable slippage, which was not affected by the air ions. Type 6 filter paper recoveries were less than AGI-4 recoveries. The air ions did not appear to affect the aerosol particle size as determined by an electron microscope.
