How to calculate specific surface area

WebSpecific surface area is a scale-dependent property, with no single true value of specific surface area definable, and thus quantities of specific surface area determined through BET theory may depend on the adsorbate molecule utilized and its adsorption cross section. [2] Concept [ edit] Websectional area of adsorbate molecule is known, it is a simple calculation to determine the total surface area m 2 of the sample. This value is normalized to the mass of the sample m 2 /g to make it independent of sample size. 4.1 Sample preparation In order to accurately determine the surface area, it
