Description
Include All. Select to include all pressure points in the table.
Insert Predefined. Click to insert a predefined (default) set of points
into the report. Use Interpolation must be selected to enable this
button. This button displays for BET reports only.
Use Interpolation. Use to indicate if the system should use the table
or interpolated data. This option is available for BET and Langmuir
reports only.
Enter values to indicate the fitted pressure range.
BET Isotherm plot. Uses BET monolayer capacity and constant to
produce an isotherm.
Autoscale x-axis. Linear x-axes begin at zero. The x-axis field
n
shows the relative pressure for BET.
Autoscale y-axis. The y-axis field shows the quantity of gas
n
adsorbed.
Overlay samples. Use to overlay sample files on the
n
BET isotherm plot.
BET Transform plot. Use to generate a traditional BET surface
area plot used to determine monolayer volume and BET C constant.
Autoscale x-axis. Linear x-axes begin at zero. The x-axis field
n
shows the relative pressure for BET.
Autoscale y-axis. The y-axis field shows BET transformation.
n
Overlay samples. Use to overlay sample files on the
n
BET transform plot.
Tabular report. Use to have a table of measured and calculated
values generated.
