Abstract:

This study explains the process of calculating BET parameters and obtaining BET areas from experimental data. Furthermore, five mathematical relationships that should be followed among the BET parameters are discussed. This paper also introduces the derivation of the experimental standard deviation and briefly touches upon evaluating the uncertainty in measurements, along with their conclusive application to BET measurements. Finally, the paper emphasizes on providing insights on using the BET model to analyze Metal Organic Frameworks (MOFs) and other materials.

Key words: BET, Data processing, Linear fitting, Error analysis
