Characterization of porous and/or divided solids / Measurement of specific surface areas and pore size distribution / Gas phase adsorption

Your needs

Determination of a specific surface area
Measurement of the adsorption capacity of a solid with respect to a gas or vapour under precise conditions of temperature and pressure
Measurement of the total porosity of a solid and its open/closed fraction
Determination of the pore size distribution (from 0.3 nm to 150 μm)
Measurement of the amount of moisture or organic vapour that a sample can fix under given conditions

Automatic adsorption units for permanent gases (N2, CO2, Ar, Kr, H2, depending on the expected surface area and the narrowness of the pores), for condensable vapours (alone or in competition two by two), depending on the temperature (from -250 to + 500°C), secondary vacuum up to 200 bars
Dynamic adsorption apparatus on columns with online product analysis
Mercury porosimetry (4000 bars)
Helium or air pycnometry for powders, solids or foamed materials

Determining an average (nano)particle size from specific surface area and skeletal density measurements
Measuring the bulk density of a powder or solid of any geometry
Determining the state of dispersion of metallic nanoparticles on a substrate
Knowing the retention capacities of porous solids subjected to a flow of pollutants in the gaseous phase
Measuring the mechanical properties of porous solids
Structural and microstructural characterization:
- X-ray diffraction
