Temkin Report Options

The Temkin isotherm is used to model adsorption data where the heat of adsorption drops linearly with increasing coverage.

Temkin Report Options Fields and Buttons Table
Field or Button Description
Calculation [group box] Select one or more of the calculation options to be used for analysis.
Pressures [button] Use to select a pressure range for report calculations and points for exclusion from calculations.

Calculation pressure range. Enter the minimum and maximum pressures to be used in the pressure table.To exclude a point from the calculations used to generate the report, select Exclude.

Exclude All. Select to exclude all pressure points in the table.

Include All. Select to include all pressure points in the table.

Pressures [button]

Use to enter a range of pressure points to be included in the report or to modify table values for pressure points.

Calculation pressure range. Enter the minimum and maximum pressures to be used in the pressure table.

Exclude All. Select to exclude all pressure points in the table.

Include All. Select to include all pressure points in the table.

Line fit pressure range.  Enter the minimum and maximum pressures for line fit.

Selected Reports
[group box]

Tabular Report. Generates a tabular report of the included samples. A tabular report contains the numeric values contributed by each sample.

Temkin Isotherm plot. Overlays the Temkin isotherm with the analysis data.

  • Autoscale x-axis. Linear x‑axes begin at zero. The x‑axis field shows the absolute pressure.
  • Autoscale y-axis. y-axes begin at zero. The y‑axis field shows the quantity of gas adsorbed.
  • Overlay samples. Use to overlay sample files on the isotherm plot.

Temkin Transform plot. Plots a linear form of the Temkin transform plot.

  • Autoscale x-axis. The x‑axis field shows the logarithm of pressure (ln).
  • Autoscale y-axis. The y‑axis field shows the quantity of gas adsorbed.
  • Overlay samples. Use to overlay sample files on the transform plot.
Specify differential heat of adsorption
[check box]
Select and enter the differential heat of adsorption at zero surface coverage. This allows inclusion of all Temkin constants.
Specify monolayer capacity [check box] Select and enter the monolayer capacity of the sample.
