V-Sorb 4800P specific surface area and pore size analyzer parameters
Analysis Method: static volumetric nitrogen adsorption
Versatility: Adsorption and desorption isotherms, Single and multi-point BET surface area analysis, T-plot external surface area, True density analysis, BJH pore size, BJH total pore volume and porosity, T-plot micropore analysis, MP micropore, Langmuir surface area, Horvath-Kawazoe (HK) micropore, Saito-Foley (SF) micropore, Dubinin-Astakhov (DA) micropore, Dubinin-Radushkevich (DR) micropore, carbon black (STSA) etc.
Measuring Ranges: 0.01m²/g to no known upper limit (surface area); 0.35 to 500nm (pore size)
Accuracy: repeatability errors ≤1%
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 sea领 performance and prolonged instrument life
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
Control System: programmable solenoid valve system with high integration and strong anti-interference ability, enhance instrument’s stability
Sample Ports: four samples’ analyzing and four samples’ degassing concurrently
Pressure Measurement: imported sectional measuring dual pressure transducer, notably improve the measuring accuracy at low P/P_o point, 0-1000Torr (0-133Kpa), 0-10Torr (0-1.33Kpa)
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%)
Partial Pressure: P/Po controllable accuracy range is 5x10^-6-0.998
Ultimate Vacuum: 4x10^-2Pa (3x10-4Torr)
Vacuum Pump: built-in bipolar vacuum pump controlled by patented software which can auto control pump’s start/stop
Sample Types: powders, particle, fiber, flakes and other materials
Adsorbate Gas: high purity nitrogen (≥99.999%), Ar, Kr, CO2, CO, C4H10 etc. non-corrosive gases are optional

V-Sorb 4800P specific surface area and pore size analyzer 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. 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.
