4072- The range of pressures selected is too small to deconvolute using this model.
Cause:
Action:
4073- The analysis gas [name] does not match the model gas [name].
Cause:
Action:
4074- The analysis temperature [nn] does not match the model temperature [nn].
Cause:
Action:
4075- The models cannot be located in the models folder. Reinstall the software.
Cause:
Action:
4077- Cannot get surface area for: [file name]

Action B:
B-26
A null result was found using the selected model.
Edit data points in the table of the Collected Data window or select
another sample file. At least two points with strictly increasing
pressures and volumes adsorbed are required for a DFT data
reduction.
The model assumes a specific gas and the sample file uses a different
one.
Select a model that assumes the same gas.
The temperature for the selected model did not match the analysis
temperature.
Select a different model.
The models could not be located. They may have been inadvertently
deleted or moved.
Reinstall the software.
The Isotherm report for the named overlay file has Per gram selected
for the Volume Adsorbed and the Isotherm report for the primary file
has a surface area option selected for the Volume Adsorbed.
Edit the Isotherm report for the named overlay file and select a
surface area option for Volume Adsorbed.
Click Overlays on the Report options window of the primary file and
remove the named overlay file from the list.
