• Autoscale X-axis - linear X-axes begin at zero. Logarithmic X-axes
begin at an appropriate value. The X-axis field shows the relative or
absolute pressure.
• Autoscale Y-axis - Y-axes begin at zero. The Y-axis field shows the
quantity of gas adsorbed.
Tabular Options
group box
Select the options to include on the report.
• Weight % - enter the weight percentage when plotting pressure
composition.
• Elapsed time - time elapsed during the analysis.
• Time between points - time elapsed between points during the
analysis.
