BET surface area analysis for aluminum dioxide

BET surface area analysis for aluminum dioxide picture FREE TO FIND US FOR TECH AND PRICE DETAILS

V-Sorb 4800S specific surface area analyzer parameters

1. Analysis Method: static volumetric nitrogen adsorption principle
2. Versatility: Adsorption and desorption isotherms, Single and multi-point BET (Brunauer-Emmett-Teller) surface area method, Langmuir surface area, t-plot external surface area analysis, True density analysis, carbon black STSA etc.
3. Measuring Ranges: 0.01 m2/g (by nitrogen)/ 0.0005m2/g (by krypton) to no known upper limit
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 Controller: V-Sorb original coolant level control 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. Control System: programmable solenoid valve system with high integration and strong anti-interference ability, enhance instrument’s stability
8. Sample Ports: four samples’ analyzing and four degassing concurrently
9. Pressure Measurement: imported sectional measuring dual pressure transducer, notably improve the measuring accuracy at low P/Po point, two transducers’ 0-1000Torr (0-133Kpa)
10. Transducer Accuracy: imported silicon thin film pressure transducer, accuracy can reach 0.1% of real reading, better than 0.1% of F.S.(full-scale), far accurate than Pirani resistance vacuum gauge(general error is 10%-15%)
11. Partial Pressure: P/Po controllable accuracy range is 5x10-6-0.998
12. Ultimate Vacuum: 4x10-2Pa (3x10-4Torr)
13. Vacuum Pump: built-in bipolar vacuum pump controlled by patented software which can auto control pump’s start/stop
14. Sample Types: powders, nanoparticle, fiber, flakes and other materials
15. Adsorbate Gas: high purity nitrogen(≥99.999%), Ar, Kr, CO2 etc. Non-corrosive gases are optional
16. Data Acquisition: high-precision and high integration data acquisition modules, minimal error, strong anti-interference ability
17. Data Reduction: Windows®-based independent developed Gold APP Instruments softwareTM, perfect versatility, produced full featured and multi-model reports(txt, word, excel, pdf)
18. Specifications: Height 22.05 inches (56cm)* Width 20.87 inches (53cm)*Depth 23.62 inches (60cm); 132 pound (60kg)
