4026- Cannot calculate Dubinin-Astkahov: bad least squares data.
Cause:
Action:
4027- Fewer than two sample files have data suitable for heat of adsorption reports.
Cause:
Action:
4028- Dubinin calculations cannot be performed because the affinity coefficient of
the analysis gas is zero.
Cause:
Action:
4029- At least two fitted data points are needed for Alpha-S calculations.
Cause:
Action:
4030- Preparations failed in primary data.

Less than two selected data points are within the fitted pressure range.
Edit the calculation assignments on the Collected Data dialog, or
change the fitted pressure range on the Dubinin report options dialog.
Less than two of the sample files you selected for heat of adsorption
reports contain appropriate data.
Edit the Quantity Adsorbed table, or select other sample files.
Dubinin values could not be calculated because the affinity coefficient
of the analysis gas is zero.
Access the Dubinin Report Adsorptive options in the sample file and
enter an appropriate value for the analysis gas.
Fewer than two data points fall within the selected Alpha-s range.
Edit the calculation assignments or the fitted Alpha-s range, or use a
different reference curve.
Appropriate data were not available to generate the report.
