BJH Adsorption/Desorption Report Options
The BJH calculation determines the mesopore volume/area distribution which accounts for both the
change in adsorbate layer thickness and the liquid condensed in pore cores. Reports can be generated
from both adsorption and desorption data.
The fields for both report options are identical unless otherwise specified. In the Selected Reports list
box, highlight BJH Adsorption (or BJH Desorption), then click Edit.
An incomplete pore distribution may be generated if a thickness curve selection is not
a good match for the sample being analyzed.

Thickness Curve
group box
Refer to t-Plot Report Options, page 5-38.
BJH Correction
group box
Select the type of correction to apply to calculations. The selected type
displays in the report header.
• Standard - uses original BJH models.
• Kruk-Jaroniec-Sayari - good for reference thickness curves.
• Faas - good for statistical thickness curves.
Minimum / Maximum
BJH width text boxes
Enter the minimum and maximum diameter (radius or width) of pores to
include in the BJH reports.
