Dollimore-Heal Adsorption/Desorption Report

The Dollimore-Heal Adsorption Report Option and the Dollimore-Heal Desorption Report Option generate reports from both adsorption and desorption data.

Dollimore-Heal Adsorption/Desorption Report
Field or Button Description
Adsorptive [button] Displays the Adsorptive Options window. The recommended adsorptives and their values are shown. Up to eight adsorptive and adsorbate property factor combinations may be specified.

Cumulative Reports
[group box]

Larger. Use to report the total volume found in pores larger than the current pore size.

Smaller. Use to report the total volume found in pores smaller than the current pore size.

Pores [group box]

Enter the minimum and maximum diameter (radius or width) of pores to include in the BJH reports.

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.

Select Reports
[group box]

Select the report names to include in the report. Highlight the report name, then click Edit to modify report parameters.

Smooth differentials
[check box]

Use to smooth all differential calculations, thus eliminating variations in the differential computation caused by noise in the input data.

Thickness Curve
[group box]

Select the thickness curve, then click Edit to modify the values in the equation for the selected curve. The Frenkel-Halsey-Hill thickness curve can be applied using the Halsey option.

Kruk-Jaroniec-Sayari / Halsey / Harkins and Jura / Broekhoff-de Boer / Carbon Black STSA. Select the thickness curve option, then click Edit. Modify the equation for the selected curve as needed.

Reference. Select Reference, then click Edit to define a t-curve by entering both the relative pressure and thickness values. One predefined curve is shipped with the analysis program and is found in the Reference directory.

To import values from an existing thickness curve (.THK file), click Open, then select the file containing the values. The table to be imported must have a .TXT or .THK file extension and have a two-column format with the relative pressures in the first column and the thickness values in the second column. Columns must be separated by a space or a tab.

Dollimore-Heal Desorption Plot Options

The fields for all plot options are identical for specifying plotting methods and customizing plots. Highlight any plot option in the Selected Reports list box in the Dollimore-Heal Report Options window, then click Edit. The fields and buttons for these reports are identical to the BJH Plot Report Options.

Dollimore-Heal Tabular Report Options

Dollimore-Heal Tabular Report Options are identical to the BJH Tabular Report Options.
