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 transducer’s macro-change.
D. Data Acquisition and
