BET Surface Area and Porosity Analyser

Micromeritics Gemini 2390 BET Surface Area and Porosity Analyser

The Micromeritics Gemini 2390 is used for the determination of surface area and porosity in materials. The instrument utilises nitrogen gas physisorption to accurately and reliably produce surface area and porosity results. Using a static volumetric technique to adsorb gas onto a sample surface, the instrument is capable of determining single and multi-point BET and Langmuir surface areas, total pore volume and BJH pore size distributions using adsorption isotherms.

The instrument incorporates a sample tube and balance tube to eliminate the effect of environmental factors on the adsorption process. This technique makes it possible to analyse very low surface areas with nitrogen gas, producing reliable and reproducible results.

The Gemini 2390 is equipped with a VacPrep system for sample preparation under vacuum at elevated temperatures before analysis.

Surface area and pore size determinations can be achieved for a variety of solid materials with surface areas achievable down to 0.1m2/g and pore sizes down to 2nm.
