V-Sorb 2800TP specific surface area and pore size analyzer parameters

1. Analysis Method: static volumetric nitrogen adsorption
2. Versatility: Adsorption and desorption isothermal curve analysis, Single and multi point BET method specific surface area analysis, Langmuir method specific surface area analysis, Average particle diameter estimation, T-plot method external surface area analysis, True density analysis, BJH total pore volume and pore size distribution analysis, T-plot method micropore analysis, MP method micropore analysis, HK method micropore analysis
3. Vacuum System: V-sorb unique stainless steel micro welding vacuum manifolds system, metal-to-metal (VCR) fittings, reduce dead space in maximum degree and also keep long duration high vacuum; the VCR metal fittings’ vacuum leak rate can reach 1x10-10 (Pa*m3/s), absolutely without usage of any O-ring sealing which will release gas to affect vacuum purity when under high vacuum condition
4. Vacuum Cavity: 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
5. Measurement Modes: “N2” and standard “N2+He” modes are available. The “N2+He” mode accords with international criterion, can guarantee the accuracy and consistence; it is not suitable to employs He to measure free space due to some samples can adsorb He in low temperature, but, ideal analysis results can get by using “N2” mode
6. Gas Dosing: Can choose He (99.999%) to dose the cold volume, not only “He+Empty cell” one type
7. Measuring Ranges: 0.01m2/g to no known upper limit(specific surface area), 0.35 to 2nm (micropore), 2-500nm (mesopore and macropore)
8. Accuracy: repeatability errors ≤1.5%
9. 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
10. Data Acquisition: high-precision and high integration data acquisition and archiving system, minimal error, strong anti-interference ability
11. Sample Ports: two samples’ analyzing and two samples’ degassing concurrently
12. Control System: programmable controller electromagnetically operated valve system with high integration and strong anti-interference ability, enhance instrument’s stability and life
13. Pressure Measurement: imported sectional measuring dual pressure transducer, notably improve the measuring accuracy at low P/Po point, 0-1000Torr (0-133Kpa), 0-10Torr (0-1.33Kpa)
14. 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%)
15. Vacuum Pump: built-in bipolar vacuum pump controlled by patented software which can auto control pump’s start/stop
16. Dewar Vessel: imported 4 liter metal made Dewar can provide at least 72 hours of unattended measurement without refilling the Dewar
17. Partial Pressure: P/Po controllable accuracy range is 5x10-6-0.995
18. Ultimate Vacuum: bipolar pump: 4x10-2Pa (3x10-4Torr), molecular pump: 5x10-6Pa
19. Sample Types: powders, particle, fiber, flakes and other materials
20. Adsorbate Gas: high purity nitrogen (≥99.999%), Ar, Kr etc. optional
21. Data Reduction: Windows®-base independent developed Gold APP softwareTM, perfect versatility, produced full featured and multi-model reports
