Nitrogen Gas Absorption: Brunauer-Emmett-Teller (BET) Model/Porosimeter/Pycnometer/Mercury Intrusion Porosimetry (MIP)
Equipment: Micromeritics Tristar II 3020
Working Principle
- Controlled gas flows into a sample
- Based on pressure and temperature changes,
detailed analysis of the
pore structure can be
measured
- In the case of porosimeter, mercury fills the pores and
measures them
Technical Information
- Distribution of pore sizes from micro to meso scale (Angstroms to 100 nm)
- Surface area and volume measurements
- Density measurement
- Quality control tool for powder analysis
