Short Description

The Autosorp 6100 is a high-precision analyser for measuring gas adsorption and desorption, which is mainly used for the characterization of nanoparticulate or porous materials (carbons, oxides, MOFs, etc.), catalysts, zeolites and other solid materials. Up to three samples with different gases and temperatures (range 77 K to 293 K) can be measured in parallel.

The range of services includes
- Determination of surface and pore properties of solid materials
- Measurement of the specific surface area and determination of pore size distribution
- Micropore and mesopore analysis using nitrogen, argon or other gas adsorption
- Cycling of reversible adsorption phenomena
- Isotherm measurements at different temperatures
- Multi-point and single-point analyses
- Volumetric and dynamic gas analysis
- Physisorption for the investigation of catalysts

Methods & Expertise for Research Infrastructure

Gas sorption analysis with nitrogen, argon, krypton or other gases enables the determination of specific surface areas and pore size distributions. With the Autosorp, the physisorption isotherm of gas molecules on the surfaces of porous solids can be determined fully automatically under isothermal conditions (77 K for N2). From the amount of adsorbed molecules as a function of the pressure p/p0, information on the specific surface area, pore size and size distribution, pore shape and surface properties (hydrophobic or hydrophilic) can be obtained using various models (BET, BJH, DFT, etc.).

At the University of Salzburg, pore and surface analyses of porous solids or nanoparticulate solids, as powders or in monolithic form (metal powders, ceramic materials, catalysts, fillers, building materials, pigments, and many other solids), can be carried out.
