V-Sorb 4800S specific surface area analyzer parameters

 

Analysis Method: static volumetric nitrogen adsorption

Versatility: Adsorption and desorption isothermal curve analysis, Single and multi point BET method specific surface area analysis, T-plot method external surface area analysis, True density analysis, Langmuir surface area analysis

Measuring Ranges: 0.01m2/g to no known upper limit(specific surface area)

Accuracy: repeatability errors 1.5%

Vacuum System: V-sorb unique assembling-installed manifolds and electromagnetically operated 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

Coolant Level Controller: V-sorb original 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

Analysis Types: N2 and N2+He two types available

Gas Dosing: Can choose He (99.999%) to dose the cold volume, not only He+Empty cell one type

Control System: programmable controller electromagnetically operated valve system with high integration and strong anti-interference ability, enhance instruments stability

Sample Ports: four samples analyzing and four degassing concurrently

Pressure Measurement: imported sectional measuring dual pressure transducer, notably improve the measuring accuracy at low P/Po point, two transducers 0-1000Torr (0-133Kpa)

Transducer Accuracy: imported silicon thin film pressure transducer, accuracy can reach 0.15% of real reading, better than 0.15% 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 5x10-6-0.995

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

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

Sample Types: powders, particle, fiber, flakes and other materials

Adsorbate Gas: high purity nitrogen(99.999%), Ar, Kr etc. optional

Data Acquisition: high-precision and high integration data acquisition modules, minimal error, strong anti-interference ability

Data Reduction: Windows®-base independent developed Gold APP softwareTM, perfect versatility, produced full featured and multi-model reports

V-Sorb 4800S specific surface area 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 controller electromagnetically operated 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 0.15% of real reading, better than 0.15% 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 assembling-installed 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 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.

 

 

V-Sorb 4800S specific surface area analyzer application

 

1. Super micro powder, nanomaterials, particle and fiber shaped specific surface area analysis.
