[group box]
Freundlich Isotherm plot. Plots the absolute pressure vs quantity adsorbed. Shows best fit line.
  • 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 Freundlich isotherm plot.
Freundlich Transform plot. Plots the log(P) vs log(Q) and the best fit.
  • Autoscale x-axis. The x-axis field shows the absolute pressure.
  • Autoscale y-axis. The y-axis field shows the quantity of gas adsorbed.
  • Overlay samples. Use to overlay sample files on the Freundlich transform plot.

Tabular report. Select to include pressure points included in the report.

Specify monolayer capacity [selection] Select and enter the monolayer capacity of the sample.
Tabular report [selection] Use to have a report of the pressure points generated.
