Understanding BET Analysis: The Science Behind Surface Area and Pore Size

The BET method, named after Brunauer, Emmett, and Teller, is a widely recognized technique for measuring the specific surface area of materials. This method relies on the principle of gas adsorption, typically using nitrogen gas at cryogenic temperatures (usually 77K)SA-9600 BET Surface Area Analyzer. The gas molecules form a multilayer on the surface of the solid material, and by measuring the volume of gas adsorbed at different relative pressures, the BET analysis can accurately determine the total surface area.

Beyond just surface area, advanced BET analyzers are also capable of determining pore size distribution and pore volume. This is achieved by analyzing the adsorption and desorption isotherms, which reveal how gas molecules interact with the pores within the material....Pore size 0.35 ～ 400 nm- Repeatability：≤ ±2 % - Test Efficiency：Multi-point BET surface area per sample: 10 ~ 15 minutes; Absorption and desorption ... Different theoretical models, such as the BJH (Barrett-Joyner-Halenda) and NLDFT (Non-Local Density Functional Theory) methods, are often employed in conjunction with BET analysis to provide detailed insights into the pore diameter and the overall porosity of the sampleBET Surface Area and Pore Size Analyzer. These models allow for the characterization of pores within a wide range, from mesoporous materials (typically 0.4-50nm or 0.35 to >500nm) to even smaller or larger pore structures.Nama Alat,SurfaceArea andPore SizeDistribution Analyzer.
