Abstract: This study conducts an in-depth analysis of the typical specific surface area analysis reports generated by the BET Assistant software, utilizing actual measurement data from the QuadraSorb evo specific surface area and pore size analyzer. Key aspects examined include the interpretation of relevant test parameters, the rationale behind the BET Assistant's point selection, and the process of fitting the linear equation. Additionally, the study highlights critical considerations for sample preparation prior to testing. This analysis provides valuable and targeted guidance for the accurate use of the specific surface area analyzer and enhances the understanding of the report content.

Key words: Specific surface area, Isotherm, BET assistant, BET equation, Linear fitting
