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
