Size-Resolved Penetration Through High-Efficiency Filter Media Typically Used for Aerosol Sampling

Popis výsledku v původním jazyce

We have developed a new, fully controlled filter testing device and have used it to measure size-resolved penetration through a typically used filtration media for (not only) atmospheric aerosol sampling. 20 membrane and fiber filter pieces (mixed cellulose ester filters, Polytetrafluoroethylene filters, quartz fiber filters, glass fiber filters, and Polycarbonate filters) of various manufacturers and filter codes were examined. High variability in the penetration curve shapes, most penetrating particlesize (MPPS) (from 20 nm to 90 nm) and penetration maxima (from 0.001 % to almost 100 %) has been found. The dependence of pressure drop on face velocity generally agrees with theory, the comparison of penetration at various face velocities proved the theoretical equations being able to determine MPPS only partially correctly. Although the variability within an individual filter of the same code is not negligible, it is small compared to the differences between the various filter types.
