The largest discrepancy seen between the impactors (Fig.
10.25
) was in filter
deposition (
EPM
<1.1μm
), where the magnitude obtained with the FPD-AVCI (1.55%
of nominal dose with Brij-coated surfaces; 1.32% with added Brij-coated filters)
was more than three times greater than equivalent values obtained using either the
sACI (0.33% Brij-coated plates; 0.43% with added Brij-coated filters) or the ACI
control (0.41%).
