BET Surface Area Measurement


BET surface area measurementBET surface area measurement uses Brunauer-Emmett-Teller (BET) theory aims to explain the physical adsorption of gas molecules on a solid surface and serves as the basis for an important analysis technique for the measurement of the specific surface area of a material.

The Gemini 2360 Analyser is a fully automatic single-point or multi-point surface area analyser that uses a flowing-gas technique in which the analysis gas flows into a tube containing the sample and into a reference tube at the same time. The internal volume and temperature surrounding both tubes are maintained at identical conditions. The only difference is the presence of the sample in the sample tube.

Surface areas as low as 0.01 m2/g are easily determined using nitogen gas as the adsorbate.

ITRI’s UK laboratory is experienced at providing BET surface area measurement results, with a fast turnaround, at very competitive rates using a Gemini 2360 BET surface area measurement analyser.
