After performing the BET analysis or the surface area analysis you will get the data sheet by which you can plot it (Origin) and from the nature of the plot whether Type I, Type II, Type III, or Type IV you can say the porosity of the synthesized material. At the time of collecting the data from the instrument you can also have the pore size data by using the BJH plot and you can compare the data to establish you opinion about the synthesized material.
If You get the BJH results there must be some data on the pore size distribution, if the report was created with the software instrument. Check the analysis parameters if BJH is checked. It looks like a report from a Micromeritics instrument, if so this is the summary report. There are more sheets int the report, check them.
