Key Information :
- Measurement stations : 3 adsorption station (non-corrosive gas probe molecules). No degassing independent system but second degassing phase on the analysis ports at room temperature
- Pressure range : Meso- and macro-porosity : 1 to 760 mmHg (10 to 10⁵ Pa)
- Pressure sensors : 1000 mmHg (resolution 10⁻³ mmHg) for the 3 ports
- Analysis temperature : 77K (liquid nitrogen), 273K (ice bath), 293 K (room temperature). The analysis temperature is common for the 3 analysis port
- Adsorbates : non-corrosive gas – no vapor
- Specific surface area : > 0. 1 m²/g (N₂)
- Degassing station : No degassing stations. Second degassing on the analysis ports : at room temperature to 350 °C (increment of 0,1°C)
- Cryogenic system : 3.5-liter Dewar, 48 h autonomy
- Accessibility : Self-service for staff, PhD students, and Master’s students after training by the technical manager
Specific Surface Area and Porosity Analyzer – Micromeritics Tristar
The Tristar is a device dedicated to measuring the textural properties (specific surface area, porosity) of the MESOPOROUS materials It allows for the characterization of meso- and macroporous structures. A preliminary external degassing (activation) phases must be done before adsorption analysis. A second degassing phase is possible on the analysis port a room temperature.
Typical Uses :
The Tristar is used for :
- Characterizing the meso- and macro-porosity of materials
- Specific surface area,
- Pore size distribution, geometry (BJH et DFT models)
Preliminary treatment : removing impurities through degassing prior to analysis
Fields of Application
- Porous inorganic or carbonaceous (mesoporous)
- Polymer and polymer-based composite materials
- Bio-based and nanostructured materials
- Applications in advanced materials and the chemical industry
Available Measurements
- Specific surface area
- Porosity analysis : pore size distribution, pore volume, geometry
