Adsorption

The Adsorption Platform provides non-destructive, high-resolution analysis of material textural properties through gas physisorption techniques. It enables the measurement of :

• Specific surface area
• Total pore volume
• Pore size distribution
• Pore geometry
• Adsorbent-adsorbate affinity
• Isosteric heat

Application Areas

Suitable for a broad range of industrial applications :

• Catalysis
• Ceramics
• Cosmetics
• Pharmaceuticals
• Coatings and paints
• Polymers and polymer-based composite
• Molecular storage (energy, depollution, agriculture, gas purification,…)
• Recovery of by-produits (biowastes, energy production…)

At IS2M, the platform is mainly used to study :

• Carbon-based materials(bio-sourced or synthetic, porous and non-porous)
• Clays
• Organized mesoporous structures
• Zeolites
• Hybrid materials such as Metal Organic Frameworks (MOFs)

Accepted Sample Types

• Dry powders(typically tens to hundreds of milligrams)
• Fabrics and organised materials
• Pellets (beads, extrudates,…)
• Films
• Monoliths

Samples must be chemically and thermally stable during degassing prior to analysis.
