During adsorption calculations, the analysis program assumes that all
pores are closed at one end. Occasionally, a percentage of pores may be
open at both ends causing disagreement in the adsorption and desorption
data or in the values for total volume and total BJH pore volume. Enter the
fraction of pores open at both ends to compensate for this error.
This field is not available for the BJH Desorption Report Options
window.
Displays the BJH Adsorptive Options window. The recommended
adsorptives and their values are shown. Up to eight adsorptive / adsorbate
property factor combinations may be specified.

Select the checkbox to smooth all differential calculations thus eliminating
variations in the differential computation caused by noise in the input data.

• Larger - select to report the total volume found in pores larger than the
current pore size.
• Smaller - select to report the total volume found in pores smaller than
the current pore size.
