f-Ratio Method Report

The f-Ratio report uses the measured isotherm and normalizes it using a reference isotherm.

f-Ratio Report
Field or Button Description
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.

Reference isotherm [group box] Browse to select a sample file to use as a reference for the isotherm. Select a file containing an isotherm measured from a non-porous sample of the same material as the current sample.

Tabular Report. Use to have a tabular report of data generated.

f-Plot. Use to generate a normalized isotherm.

  • Autoscale x-axis. The x-axis field is dimensionless in units of f-ratio.
  • Autoscale y-axis. The y-axis field shows the quantity of gas adsorbed.
  • Overlay samples. Use to overlay sample files on the f-plot.
