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
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

4800S 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
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.
