Horvath-Kawazoe Report
The Horvath-Kawazoe method plots individual peaks for different pore sizes even if the difference between one pore size and the next is only one angstrom (0.10 nm) or less.
Field or Button | Description | ||
---|---|---|---|
Apply Cheng-Yang correction [selection] |
Use to apply the Cheng-Yang correction to the pore size analysis. This correction substitutes the Langmuir equation of state for Henry’s Law in the Horvath-Kawazoe derivation. | ||
Interaction Parameter [group box] |
Use to determine which interaction parameter will be used in the report. These options are disabled if Sphere is selected in the Pore Geometry group box. Computed. Use to calculate using the parameters on the Horvath-Kawazoe Physical Properties window (click Properties to display the Physical Properties window). The interaction parameter is recalculated each time a parameter in the Physical Properties window is edited. Entered. Calculates using the value entered in the text box. |
||
Pore Geometry [group box] |
Select the option that best represents the physical geometry of the micropores in the sample material. When Sphere is selected, options in the Interaction Parameter group box are disabled. | ||
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. |
||
Properties [button] |
Click to view or edit the constants describing the physical properties of the adsorbent and adsorptive. Adsorbent. Contains the parameters for the sample. If using Computed for the interaction parameter, all fields are enabled. If using Entered, only the values in the Diameter and Diameter at zero energy text fields may be edited.
Adsorptive. Contains the parameters for the adsorptives. If using Computed for the interaction parameter, all fields are enabled. If using Entered, only the values in the Diameter and Diameter at zero energy text fields may be edited.
* Option is disabled if Entered is selected in the Interactions Parameter group box. |

Select Reports [group box] |
Select the types of reports to generate. Highlight the report, then click Edit to modify report parameters. | ||
Smooth differentials [selection] | Use to smooth all differential calculations, thus eliminating variations in the differential computation caused by noise in the input data. | ||
