Dear All,

I have read and watched many sources of how to evaluate non-linear isotherm models using Origin software, but unfortunately, I did not succeed. Do you have any helpful file or guidance for this problem? or I would be grateful if you could send me saved isotherm models which are in the place of software installation. In this way, I can add them to my origin software. I do not know exactly what information should I write in gaps in software when I am adding a non-linear model (please find enclosed).

I would appreciate your immediate attention to this matter.

Cheers,

Hamid
