4. Fuel cells, catalysts, additives, adsorbent, ceramics, magnetic materials, energy storage materials etc. surface area data determination.
5. Other researches concern specific surface area performance.

V-Sorb 2800S surface area analyzer specifications

1. Analysis Principle: static volumetric nitrogen adsorption
2. Testing Methods: adsorption and desorption isotherms, single and multi-point BET (Brunauer-Emmett-Teller) surface area, Average particle diameter estimation, t-plot external surface area, true density analysis, Langmuir surface area, carbon black (STSA-Statistical thickness surface area), adsorption constant C.
3. Measuring Ranges: 0.01 m2/g (by nitrogen)/ 0.0005m2/g (by krypton) to no known upper limit
4. Accuracy: repeatability errors within 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; decrease connecting points; strengthen sealing performance and prolonged instrument working life
6. Coolant Level Prober: 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. Sample Pretreatment: the whole pretreatment 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 stability and life
9. Sample Ports: two samples analyzing and two samples degassing concurrently
10. Pressure Measurement: imported sectional measuring dual pressure transducer, notably improve the measuring accuracy at low P/Po point, standard equips 1000Torr (0-133Kpa) transducer, 10 Torr is option
11. 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%)

17. Data Acquisition: high-precision and high integration data acquisition modules, minimal error, strong anti-interference ability
18. Data Reduction: Windows-based independent developed Gold APP Instruments software, perfect versatility, produced full featured and multi-model reports

V-Sorb 2800S surface area analyzer technical features

A: Vacuum System
1. Unique integral manifolds system, decrease connecting points apparently, reduce leak rate, improve ultimate vacuum.
2. Modularity design can configure as customer requests, benefits future functions extension and instrument maintenance.
3. Imported bipolar vacuum pump, low noise, stable working, oil-return prevention; ultimate vacuum can reach 4x10-2Pa (3x10-4Torr).

B: Control System
1. Industry type programmable solenoid valve system, strong anti-interference ability, convenient for installation and uninstallation.
2. Separated analysis and pretreatment manifolds can prevent foreign matter to contaminate manifolds during sample pretreatment.

C. Measures for Improving Accuracy
1. Imported silicon thin film pressure transducer, accuracy can reach 0.1% of real reading, better than 0.1% of F.S. (full-scale).
2. 10Torr (optional) and 1000Torr dual pressure transducers, sectional measurement in pressure range can reduce errors in low vacuum.
3. Unique monolithic manifolds system, decrease connecting points and reduce leak rate apparently.
4. Original stepping coolant level control system, 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.
5. Pioneered gas outlet and inlet control system can efficiently prevent samples splash in vacuuming and gas inlet procedures, guarantee clean manifolds and sample weight unchanged, avoid zero and liner drifting caused by transducers macro-change.

D. Data Acquisition and Reduction
1. High precision and integration data acquisition module is easy to connect, minimal errors and strong anti-interference ability; standard 485 communication mode is good for analyzers applications extension and interconnection, can also conveniently switched to RS232 and USB modes.
2. Multi calculating methods for data reduction provides all-round sample analysis options; powerful data archiving and searching system helps a lot for data management.
