m pore dimension polycarbonate membrane filters (borderline importance, chance = 0.0536). It should be pointed out that it took the SMPS 270 s to finish the two scans for obtaining a person set of collection efficiency info. The final results in Figure 6a recommend that the gathering efficiency modified so rapidly for this individual kind of filter that the transform could possibly be considerable throughout Each individual measurement spanning 270 s, which might bring about significant typical deviations in assortment efficiency.
