Quantachrome  Nova 4200e BET

BET Analyzer

 Bruanauer-Emmett-Teller (BET) measures the surface area (m2/g) of solid materials through a gas adsorption analysis.  Our instrument can analyze up to four samples at one time.  Both adsorption and desorption isotherms can be measured, which can provide information on the adsorption process and the shape of the pores in our material.  You can perform single or multi-point BET analysis to determine the surface area of the sample.  Additional analysis can provide total pore volume and distribution or micropore width, area, volume, and adsorption energy.

APPLICATIONS

  • Separation Technologies Design: Pore volume analysis of absorbent materials, including activated carbons, zeolites, metal organic frameworks (MOFs) and porous polymers/composites.
  • Pharmaceuticals: Surface area analysis of carriers (e.g., nanoparticles, microparticles) to predict drug loading capacity, release kinetics, and bioavailability
  • Cement and Building Materials: Characterization of cement pastes and concrete aggregates, where surface area affects hydration kinetics, strength development, and durability.
  • Soils and sediments: BET helps quantify the surface area of particles, which influences contaminant adsorption and remediation efficiency
