BET
Engelsk bruksanvisning.docxThe method of BrunauerBrunauer, EmmetEmmet, and Teller Teller is employed to determine surface area on a model of adsorption which incorporates multilayer coverage.
Application
1. PURPOSE PURPOSE
The Micromeritics Tri Star 3000 Surface Area and Porosity Analyzer is used for N2 adsorption measurements.
2. SCOPE SCOPE
- Calculation of specific surface area from adsorption and desorption isotherm branch according to BET or single point method
...
- Calculation of pore volume and pore size distribution from adsorption and desorption isotherm branch according to BJH method.
3. TARGET GROUP
Solid state materials, micro-, mesoporous materials
...
Single point approach – method for calculation surface area based on the point on isotherm which correspond to the formation of the statistic monolayer on the surface.
