BET SystemQuantachrome NOVA 3000 series (Model N32-11) High Speed Gas Sorption Analyzer

The following measurements can be done by the analyzer:

  • Multipoint and single point BET (Brunauer-Emmett-Teller) surface area:  0.01 – over 2,000 m2/g
  • External surface area (STSA)
  • 100 points adsorption isotherms
  • 100 points desorption isotherms
  • Total pore volume: minimum pore volume: better than 2.2 x 10-6 cc
  • Average pore radius: pore diameter range: 3.5 – 2,000 Å
  • BJH pore size distribution based on the adsorption/desorption isotherm
  • Approximate sample volume and density
