t-Plot
A least-squares analysis fit is performed on the (
t
i
,
N
ads,
i
) data pairs where t
i
is the independent variable
and N
ads,i
is the dependent variable. Only the values of
t
i
between
t
min
and
t
max
, the minimum and max-
imum thickness, are used. The following are calculated:
a.) Slope (
S
cm

/g-Å STP)
b.) Y-intercept (
Y

cm

/g STP)
c.) Error of the slope (

cm

/g-Å STP)
d.) Error of the Y-intercept (

/g STP)
e.) Correlation coefficient
Using the results of the above calculations, the following can be calculated:
External Surface Area (m

/g):
where

F
=
surface area correction factor, user-entered on the

window
V
mol
=
liquid molar volume, from the fluid property information
Micropore Surface Area (m

/g):
where
SA
total
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
total
is the BET surface area value calculated using a set of default parameters.
