Enter the value to correct for surface areas that are not smooth. This
brings the values for BET surface area and micropore surface area
into accordance. For most samples, the default value of 1.000 is
adequate.
Select the surface area value used for thickness calculations. BET is
the most commonly used option.
Select the thickness curve, then click
