Liquid-liquid displacement porosimetry (LLDP) has been used to characterize several UF
membranes in a wide range of molecular weight cut-offs (MWCO). A new method to
convert porosimetric data into pore size distributions and related information has been
developed based on assuming log-normal pore size distributions. The results of this are in
good agreement with those from the customary data conversion algorithm (as derived by
Grabar and Nikitine). The proposed method can also be used when a reduced number of
experimental data points is available, leading to a significant reduction of data acquisition
time needed to complete a reliable analysis.
