Bruanauer-Emmett-Teller (BET) measures the surface area (m2/g) of solid materials through a gas adsorption analysis.  Our instrument is a Quantachrome  Nova 4200e with four degas and four analysis ports and we mainly utilize nitrogen as the adsorbate.  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.  Common samples that are analyzed using BET include engineered nanomaterial, mesoporous carbon, mineral phases, metal-organic frameworks, soils, and polymers. 

The instrument is located in IATL 196 and is managed by Dr. Michael Sinnwell.
