4026- Cannot calculate Dubinin-Astkahov: bad least squares data.
Cause: Less than two selected data points are within the fitted pressure range.
Action: Edit the calculation assignments on the Collected Data dialog, or
change the fitted pressure range on the Dubinin report options dialog.
4027- Fewer than two sample files have data suitable for heat of adsorption reports.
Cause: Less than two of the sample files you selected for heat of adsorption
reports contain appropriate data.
Action: Edit the Quantity Adsorbed table, or select other sample files.
4028- Dubinin calculations cannot be performed because the affinity coefficient of
the analysis gas is zero.
Cause: Dubinin values could not be calculated because the affinity coefficient
of the analysis gas is zero.
Action: Access the Dubinin Report Adsorptive options in the sample file and
enter an appropriate value for the analysis gas.
4029- At least two fitted data points are needed for Alpha-S calculations.
Cause: Fewer than two data points fall within the selected Alpha-s range.
Action: Edit the calculation assignments or the fitted Alpha-s range, or use a
different reference curve.
