Using the results of the above calculations, the following can be calculated:
External Surface Area (m
2
/g):
where
F = surface area correction factor, user-entered on the t-Plot Report Options dialog
D = density conversion factor, user-entered on the Adsorptive Properties dialog
Micropore Surface Area (m
2
/g):
where SA
TOT
is the BET surface area if the user enabled the BET report exclusively, or Langmuir sur-
face area if the user enabled the Langmuir report exclusively. If neither report has been selected, SA
TOT
is the BET surface area value calculated using a set of default parameters.
Micropore Volume (cm
