Brunauer-Emmett-Teller (BET) theory aims to explain the physical adsorption of gas molecules on a solid surface and serves as the basis for an important analysis technique .

In BET surface area analysis, nitrogen is usually used because of its availability in high purity and its strong interaction with most solids. Because the .The BET theory, developed by Stephen Brunauer, Paul Hugh Emmett, and Edward Teller in 1938, extends the Langmuir adsorption model to multilayer adsorption. The theory .What is BET analysis? While BET technically refers to the theory used in the determination of specific surface area, the term is often extended to refer to surface area and pore size measurement by gas adsorption .BET (Brunauer, Emmet, and Teller) theory is the most popular model used to determine the surface area of the exposed surface of a solid sample on the molecular scale. Typically, BET analysis is performed using nitrogen .

Brunauer–Emmett–Teller (BET) theory is used to measure the surface area of solid or porous materials. It gives important information on their physical structure as the area of .The BET theory (abbreviated from Brunner-Emmett-Teller theory) is used to measure the surface area of solid or porous materials. It gives important information on their physical .Gas adsorption is a powerful analysis technique to determine the specific surface area and pore size distribution of solid, porous materials. Surface area and pore size are of .

BET analysis provides precise specific surface area evaluation of materials by nitrogen multilayer adsorption measured as a function of relative pressure using a fully automated .Brunauer–Emmett–Teller (BET) theory is used to measure the surface area of solid or porous materials. It gives important information on their physical structure as the area of a material’s surface affects how that solid will interact with its environment. Many properties such as dissolution rates, catalytic activity, moisture retention, and shelf life are often .Degassing Temperature Range: Ambient – 350°C.
