Purpose and area of application

   The laboratory of physical and chemical methods of investigations of BSTU carry out investigation of the surface area and porosity for materials:

Directions of research:
-Determination of the surface area of catalysts, adsorbents and other materials;
-Studying of the isotherms of adsorption and desorption;
-Determination of the pore side distribution based on the adsorption or desorption isotherm;
-Investigation of the type and parameters of porosity;
-Definition of the adsorptive capacity and activity of porous stuffs;

Equipment:  

    High Speed Gas Sorption Analyzer NOVA 2200 (Quantachrome Corp. USA)

   The NOVA 2200 will perform rapid and accurate sorption measurements of N₂ (nitrogen gas), Ar (argon), CO₂ (carbon dioxide), CO (carbon monooxide), O₂ (oxygen) or other non-corrosive gases on solid surfaces. The theoretical basis for the operation of the NOVA is Brunauer-Emmett-Teller (BET) method is the most widely used procedure for the determination of the surface area of solid materials and involves the use of the BET equation.
