Gold APP Instruments Surface Area Analyzer

We are offering
1.Analysis Method: static volumetric nitrogen adsorption principle
2. Versatility: Adsorption and desorption isotherms, Single and multi-point BET (Brunauer-Emmett-Teller) surface area, Langmuir method surface area, Average particle diameter estimation, t-plot external surface area, True density analysis, BJH (Barrett-Joyner-Halenda) total pore volume and pore size distribution analysis, t-plot method micropore analysis, MP micropore, Dubinin-Radushkevich (DR) and Dubinin-Astakhov (DA) micropore surface area
3. Measuring Ranges: 0.01 m2g (by nitrogen) 0.0005m2g (by krypton) to no known upper limit (specific surface area); 2 to 500nm (pore size)
4. Accuracy: repeatability errors ≤1%
5. Vacuum System: V-Sorb unique monolithic manifolds and solenoid valve control system, greatly reduce the dead volume; improve the adsorbate micro-change sensitivity; enhance pore size distribution analysis resolution; decrease connecting points; strengthen sealing performance and prolonged instrument life
6. Coolant Level Prober: V-Sorb original coolant level probe system with temperature probe, ensure the coolant level unchanged when compares with sample cells in the whole analysis process, completely eliminate the analysis errors caused by dead volume change
7. Sample Treatment: the whole treatment procedures are controlled by dedicated software, as well with a start time preset function which can realize unattended operation at night
8. Control System: programmable solenoid valve system with high integration and strong anti-interference ability, enhance instrument’s stability and life
9. Sample Ports:2 samples analyzing and 2 samples degassing concurrently
10. Pressure Measurement: imported sectional measuring dual pressure transducer, notably improve the measuring accuracy at low PPo point, 0-1000Torr (0-133Kpa), 0-10Torr (0-1.33Kpa)
