V-Sorb 4800P surface area and pore size analyzer introduction
V-Sorb 4800P surface area and pore size analyzer be researched and produced by Gold APP Instruments who is an expert of physisorption analyzers over 15 years. The surface area and pore size determination with using of static volumetric principle which be widely accepted and recognized by ISO and ASTM etc. standards like ASTM D6556, ASTM D4820, ISO 9277 and ISO 15901 and so on. It mostly be used in fields like additives, catalysts, ceramics, coatings, filtration, food, drugs, metal powder, mining, silica, plastic, polymers etc.
V-Sorb 4800P surface area and pore size analyzer specifications
1. Analysis Method: static volumetric nitrogen adsorption.
2. Testing Data: adsorption & desorption isotherms, BET surface area, Langmuir surface area, t-plot external surface area, BJH mesopore size, t-plot micropore, MP micropore, HK micropore, SF micropore, DA micropore, DR micropore size, pore size width, pore volume etc.
3. 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 (meso & micropore).
4. Accuracy: repeatability errors ≤1%.
5. Vacuum System: V-Sorb unique monolithic manifolds and solenoid valve control system.
6. Coolant Level Prober: V-Sorb original coolant level control system with temperature prober.
7. Sample Ports: four samples analyzing and four samples degassing.
8. Pressure Measurement: branded dual pressure transducer, 0-1000Torr (0-133Kpa) and 0-1Torr (0-1.33Kpa). Accuracy can reach 0.1% of real reading, better than 0.1% of F.S. (full-scale).
9. Partial Pressure: P/Po controllable accuracy range is 5x10-6-0.998.
10. Ultimate Vacuum: 4x10-2Pa (3x10-4Torr).
11. Vacuum Pump: built-in bipolar vacuum pump controlled by software, can automatically control pump working.
V-Sorb 4800P surface area and pore size analyzer technical features
A: Vacuum System
1. Unique integral manifolds system, decrease connecting points apparently, reduce leak rate, improve ultimate vacuum.
2. Modularity design supports to install as customized requests, this benefits future upgrading and maintenance.
B: Control System
1. Branded programmable solenoid valve system, strong anti-interference ability, convenient for installation and uninstallation.
2. Separated analysis and pretreatment system can prevent foreign matter to contaminate analysis manifolds, further to avoid gas leakage.
C. Measures for Improving Accuracy
1. 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 the dead volume.
2. Pioneered gas outlet and inlet control system can efficiently prevent sample splash in vacuuming and gas input procedures, this can guarantee clean manifolds, avoid gas leak.
D. Data Acquisition and Reduction
1. High precision and integration data acquisition module is easy to connect, minimal errors and strong anti-interference ability; standard RJ45 communication mode benefits for future upgrading.
2. Multi calculating methods for data reduction provides all-round sample analysis options; powerful data archiving and searching system helps a lot for data management.
