2.      Product quality control for powder materials related corporations.

3.      Research institutes, universities for BET (Brunauer-Emmett-Teller) theory teaching.

4.      Fuel cells, catalysts, additives, adsorbent, ceramics, magnetic materials, energy storage materials etc.

5.      Other researches concern specific surface area performance.




1.      Analysis Method: static volumetric nitrogen adsorption principle

2.      Versatility: 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 ≤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 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 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 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, 0-1000Torr (0-133Kpa), 0-10Torr (0-1.33Kpa)

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%)

12.  Partial Pressure: P/Po controllable accuracy range is 5x10-6-0.998

13.  Ultimate Vacuum: 4x10-2Pa (3x10-4 Torr)

14.  Vacuum Pump: built-in bipolar vacuum pump controlled by patented software which can auto control pump's start/stop

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 softwareTM, perfect versatility, produced full featured and multi-model reports




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.      Germany imported bipolar vacuum pump, low noise, stable working, oil-return prevention; ultimate vacuum can reach 4x10-2Pa (3x10-4Torr).


B: Control System

1.      Industry used programmable solenoid valve system, strong anti-interference ability, convenient for installation and uninstallation.

2.      Separated analysis and treatment manifolds can prevent foreign matter to contaminate manifolds in sample treatment.


C. Measures for Improving Accuracy

1.      Imported silicon thin film capacitive pressure transducer, accuracy can reach 0.1% of real reading, better than 0.1% of F.S. (full-scale).

2.      0-10Torr (optional) and 0-1000Torr dual pressure transducers, sectional measurement in pressure range can reduce errors in low vacuum, 0-10Torr silicon thin film transducer is highly accurate than Pirani resistance vacuum gauge (general error is 10%-15%).

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 sample splash in evacuation and gas inlet process, guarantee clean manifolds and sample weight unchanged, avoid zero and liner drifting caused by transducer's 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 analyzer's 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.
