Computer Controlled Device for Determination of Textural and Adsorption Properties of Catalysts and Solid Materials (Micromeritics, ASAP 2020 MP/C)

The device enables: determination of single- and multipoint BET surface area of solid materials in the range of 0.001-3000 m2/g; determination of Langmuir surface area; determination of Freundlich and Temkin isotherms; determination of pore volume and pore area distributions in the range 0.35-500 nm and the evaluation of results by means of various methods (such as MP method, t-plot, alpha-S plot, Dubinin-Radushkevich method, Dubinin-Astakhov method, Horvath-Kavazoe method, BJH method, etc.); analysis of adsorption/desorption isotherms by means of DFT (Density Functional Theory) method in the entire range of micro- and mesopores; determination of adsorption/desorption isotherms and heat of adsorption by using various adsorbates (N2, Ar, Kr, CO, CO2, H2, He, water vapour, saturated and unsaturated hydrocarbons); cyclic determination of adsorption/desorption isotherms in the selected pressure range; determination of rate of adsorption of various adsorbates on the surface of investigated solid at a selected pressure; determination of acidic/basic properties of catalysts and other solids by means of static (volumetric) method; determination of active metal area, crystallite size, active metal dispersion, heat of chemical adsorption, strong and weak chemisorption by means of static (volumetric) chemisorption method.
