  • Specific Surface Area And Micropore Size Analyser Manufacturer - China

    price: 1.00 Dollar US$

    V-Sorb 2800TP specific surface area and pore size distribution analyser application 1. Super micro powder, nanomaterials, nanoparticle and fiber shaped specific surface area, pore size distribution, pore volume etc. analysis.
    2. Product quality control for powder materials related corporations. 3. Research institutes, universities for BET (Brunauer-Emmett-Teller) theory teaching.
    4. Full cells, catalysts, additives, adsorbent, ceramics, magnetic materials, energy storage materials etc.
    5. Other researches concern specific surface area, pore size, pore volume performance. V-Sorb 2800TP specific surface area and pore size distribution analyser parameters 1. Analysis Method: static volumetric nitrogen adsorption principle
    2. Versatility: Adsorption and desorption isotherms, Single and multi-point BET (Brunauer-Emmett-Teller) surface area, Langmuir surface area, Average particle diameter estimation, T-plot external specific surface area, True density analysis, BJH (Barrett-Joyner-Halenda) total pore volume and pore size distribution, T-plot micropore, MP method micropore, Horvath-Kawazoe (HK) micropore, Saito-Foley (SF) micropore, Dubinin-Radushkevich (DR) micropore, Dubinin-Astakhov (DA) micropore, carbon black (STSA) etc. 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 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
    5. Measuring Ranges: 0.01 m2/g (by nitrogen)/ 0.0005m2/g (by krypton) to no known upper limit (specific surface area); 0.35 to 500nm (pore size)
    6. Accuracy: repeatability errors within 1%
    7. Coolant Level Prober: 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
    8. Data Acquisition: high-precision and high integration data acquisition and archiving system, minimal error, strong anti-interference ability
    9. Sample Ports: two samples’ analyzing and two samples degassing concurrently
    10. Control System: programmable solenoid valve system with high integration and strong anti-interference ability, enhance instrument’s stability and life
    11. Pressure Measurement: imported sectional measuring dual pressure transducer, notably improve the measuring accuracy at low P/Po point, 0-1000Torr, 0-1Torr and 0-0.1Torr three pressure transducers are equipped
    12. Transducer Accuracy: imported silicon thin film pressure transducer, accuracy can reach 0.1% of real reading, better than 0.1% of F.S.(full-scale), far accurate than Pirani resistance vacuum gauge(general error is 10%-15%)
    13. Vacuum Pump: built-in bipolar vacuum pump controlled by patented software which can auto control pump’s start/stop
    14. Dewar Vessel: imported 4 liter metal made Dewar can provide at least 72 hours of unattended measurement without refilling the Dewar 15. Partial Pressure: P/Po controllable accuracy range is 5x10-6-0.998
    16. Ultimate Vacuum: bipolar pump: 4x10-2Pa (3x10-4Torr), molecular pump: 5x10-6Pa
    17. Sample Types: powders, nanoparticle, fiber, flakes and other materials
    18. Adsorbate Gas: high purity nitrogen (99.999%), Ar, Kr, CO, CO2, C4H10 etc. non-corrosive gases are optional
    19. Data Reduction: Windows-based independent developed Gold APP Instruments software, perfect versatility, produced full featured and multi-model reports
