    Thank you so much, this really helps my graduation project. For someone not familiar with OriginLab, the calculations for the slope and y-intercept could also easily be done in Excel itself.

    It was very helpful!! Thank you so much. I am working on Binary gas adsorption. I am thinking of using MPD(Myers-Prausnitz-Dubinin) model which is the combination of the IAST with a formulation of the pure gas isotherms with the help of DA(Dubinin-Astakhov) equation. but then I was stuck in solving IAST equation which has incomplete gamma function. Do you have any excel sheet for this? I would like to estimate binary gas adsorption on activated carbon by using pure gas isotherm.

    Hi! I have a question regarding the concentration range. For my thesis I used really low Ci values from 0.1 to 0.3 and thus I got some really low Ce for example 0,01. What made you pick that range of concentrations ? Cause after calculating the log of Ce I got negative values so I got a bit lost in here. Really appreciate your help
