4072- The range of pressures selected is too small to deconvolute using this model.
4073- The analysis gas [name] does not match the model gas [name].
4074- The analysis temperature [nn] does not match the model temperature [nn].
4075- The models cannot be located in the models folder. Reinstall the software.
4077- Cannot get surface area for: [file name]
Cause: A null result was found using the selected model.
Action: 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.
Cause: The model assumes a specific gas and the sample file uses a different
one.
Action: Select a model that assumes the same gas.
Cause: The temperature for the selected model did not match the analysis
temperature.
Action: Select a different model.
Cause: The models could not be located. They may have been inadvertently
deleted or moved.
Action: Reinstall the software.
Cause: 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.
Action A: Edit the Isotherm report for the named overlay file and select a
surface area option for Volume Adsorbed.
Action B: Click Overlays on the Report options window of the primary file and
remove the named overlay file from the list.
