BET Adsorption Testing
BET (Brunauer–Emmett–Teller) specific surface area test method is used to measure specific surface area of materials.
|Equipment||Micromeritics (USA), ASAP2020; Tristar 3020 M|
|Application||Specific surface area, pore volume, pore size, and nitrogen adsorption and desorption curves of nanomaterials, porous materials and catalysts, etc.|
Surface Area Analysis (N2 is the default
Micro-porosity Analysis (0.5-2 nm)
Meso-porosity Analysis (2-50 nm)
Total porosity Analysis (0.5-50 nm)
Adsorption capacity test (N2，Ar，CO2，H2，O2，CH4)
Sample should be dry.
Powder: >0.2g (weight)
Film: <0.5*0.5 cm² (dimension)
Particle: Φ>0.2 mm (particle diameter)
