The BET equation (named after Brunauer, Emmett, and Teller who developed the theory) was first published in 1938 (Brunauer, 1938), and continues to be the most widely used method to determine the number of molecules/atoms of a gas needed to form a monolayer, X m, of adsorbed gas on a solid surface (Thommes, 2015).The BET equation (Equation .%PDF-1.6 %âãÏÓ 495 0 obj > endobj 512 0 obj >/Filter/FlateDecode/ID[117B4AC0F6CDDA44844A0A0C7BB420D6>63569891376292439088CCBA67644654>]/Index[495 34]/Info 494 0 R .BET SURFACE AREA SERVICES . Surface Area is a measure of the exposed surface of a solid sample on the molecular scale. The BET (Brunauer, Emmet, and Teller) theory is the most popular model used to determine the area; results according to the Langmuir model are also available. . Surface area measurement is an important analysis used in many .The BET surface area equation, where S t is the specific surface area of the sample, v m is the monolayer volume, N is Avogadro's number (6.02214076×10 23 particles per mole), . In addition to surface area, BET analysis can provide information about the porosity of a material. The total pore volume can be estimated from the amount of gas .
BET Specific Surface Area is recognized by numerous standards and guidance agencies, including the ISO, ASTM, USP and EP. The ability to measure a broad range of surfaces from non-porous solids to highly . The BET plots from the various adsorption-desorption runs are presented in Figures 2A–C.By default, BET analysis is usually performed over the range of 0.05 ≤ P/P o ≤ 0.35, with the implicit assumption that a monolayer is formed is within this relative pressure range without the consideration of the type of material used. The BET surface . Surface area estimation using the Brunauer–Emmett–Teller (BET) analysis has been beset by difficulties. The BET model has been applied routinely to systems that break its basic assumptions.
