Analysis Method: static volumetric nitrogen adsorption principle
Versatility: Adsorption and desorption isotherms,Single and multi-point BET surface area, Average particle
Diameter estimation, t-plot external surface area,True density analysis, Langmuir surface area, carbon black
(STSA), adsorption constant C
Measuring Ranges: 0.005 m2/g to no known upper limit (surface area)
Accuracy: repeatability errors ≤1%
Vacuum System: unique monolithic manifolds and pneumatic valves control system, greatly reduce the dead volume; improve the absorbate micro-change sensitivity; decrease connecting points; strengthen sealing performance and prolonged instrument life.
Coolant Level Prober: 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.
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.
Control System: programmable solenoid valve system with high integration and strong anti-interference ability to enhance instrument's stability and life.
Sample Ports: two samples' analyzing and two samples' degassing concurrently.
Pressure Measurement: imported sectional measuring dual presure transducer, notably improve the measuring accuracy at low P/Po point, 0-1000 Torr (0-133Kpa), 0-10 Torr (0-1.33Kpa) (optional).
Transducer Accuracy: imported silicon thin film pressure transducer,accuracy can reach 0.1% of real reading,betterthan0.1%ofF.S.(full-scale),far accurate than Pirani resistance vacuum gauge (general error is10%-15%).
Partial Pressure: P/Po controllable accuracy range is 5*10-6 - 0.998.
Ultimate Vacuum: 4x10-2Pa (3x10-4 Torr).
Vacuum Pump: built-in bipolar rotary 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, CO, C02, C4H10 etc.non-corrosive gases are optional.
Data Reduction: Windows®-based independent developed, perfect versatility, produced full featured and multi-model reports.
