Meso- to Microporous Materials Adsorption Analysis System — Applications, Principles, and Specifications
Application Scope
- Surface area and pore size analysis for meso- to microporous materials
- Supports BET (single-point/multi-point) and pore size distribution (BJH, HK, SF, NLDFT, etc.)
- Supported gases: N₂, Ar, Kr, H₂, O₂, CO₂, CO, NH₃, CH₄, and other non-corrosive gases
- Suitable for both industrial high-volume testing and scientific research, especially for macroporous materials such as precipitated silica and alumina
Measurement Principles
- Static volumetric gas adsorption method: Multiple analysis ports share the same Dewar and gas supply to improve consistency and reduce sample-to-sample variation.
- Adsorption/desorption isotherm measurement: Pore size and specific surface area are analyzed based on isothermal adsorption and desorption curves.
Instrument Features & Benefits
- High-throughput design: Up to four samples can be tested simultaneously; single-sample BET testing time is as short as 20 minutes
- Vtech technology suite:
- Vspace: cold free space control
- Vlevel: liquid nitrogen level control to ensure thermal stability
- Vstable: improved repeatability for large-pore materials
- Vctrl: prevents sample carryover/dispersion to protect the gas path and improve operational safety
- Independent P₀ sensor (dedicated reference pressure measurement) to ensure stability
- Software supports remote monitoring, automatic degassing, and liquid nitrogen refill functions
- Solenoid valves with LED indicators to show real-time operating status
- Independent vacuum degassing station (up to 400°C, ±1°C accuracy)
