V-Sorb 2800TP surface area and pore size distribution analyser

 V-Sorb 2800TP surface area and pore size distribution analyser introduction

V-Sorb 2800TP surface area and pore size distribution analyser is manufactured by Gold APP Instruments engineers for specific surface area, pore volume and pore size related data testing, especially for super micropore testing. It has a turbo molecular vacuum pump and 0.1 torr pressure sensor, also equips 316L stainless steel manifold pipelines, can make to reach a very low pressure with high accuracy.

V-Sorb 2800TP surface area and pore size distribution analyser applications

1.     Super micro powder, nanomaterials, particle and fiber etc. samples specific surface area, pore size distribution, pore volume etc. analysis.

2.     Government institutes and universities for researching work

V-Sorb 2800TP surface area and pore size distribution analyser parameters

1.     Test Principle: static volumetric adsorption

2.     Test Data: adsorption and desorption isotherms, single and multipoint BET (Brunauer-Emmett-Teller) surface area, Langmuir surface area, external surface area, BJH (Barrett-Joyner-Halenda) total pore volume and pore size distribution, T-plot micropore, MP 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.     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)

5.     Accuracy: repeatability errors within 1%

6.     Data Acquisition: high-precision and high integration data acquisition and archiving system, minimal error, strong anti-interference ability

7.     Sample Ports: 2 analyzing and 2 degassing work simultaneously and independently

8.     Control System: programmable solenoid valve system with high integration and strong anti-interference ability, enhance instrument’s stability and life

9.     Pressure Measurement: branded pressure transducer greatly improve the measuring accuracy at low P/Po point, 1000Torr, 1Torr and 0.1Torr three pressure transducers are equipped

10.  Transducer Accuracy: pressure transducer accuracy can reach 0.1% of real reading

11.  Vacuum Pump: built-in mechanical vacuum pump and turbo pump be controlled by software

12.  Dewar: branded 4 liter stainless steel Dewar can provide at least 72 hours of unattended measurement without refilling the LN2

13.  Partial Pressure: P/Po controllable accuracy range is 5x10-8-0.998

14.  Ultimate Vacuum: bipolar pump: 4x10-2Pa (3x10-4Torr), molecular pump: 5x10-8 mbar

V-Sorb 2800TP surface area and pore size distribution analyser features

1.     Stainless steel micro welding vacuum manifolds system can reduce the leak rate apparently and improve ultimate vacuum.

2.     Micro welding vacuum system can decrease manifolds dead volume, increases measuring sensitivity and improve accuracy.

3.     Equip turbo vacuum pump, ultimate vacuum value can reach 5x10-8-0.998 mbar, maintenance free, convenient to use.

4.     Branded high vacuum pneumatic valve sealing performance is up to 5x10-12 (Pa m3/s).

5.     Fully metal-to-metal VCR connecting eliminate O-ring gas release problem when under high vacuum circumstance, efficiently improve ultimate vacuum and analysis reliability.

6.     Modularity design can configure as customer requests, easy for future upgrading and maintenance.

7.     Programmable pneumatic valve system with high integration and strong anti-interference ability.

8.     Multi calculating formulas for data reduction provides all-round sample analysis options; powerful data archiving and searching system helps a lot for data management.
