Product Details
Brand Name: | Gold APP Instruments | Place of Origin: | China | Model Number: | V-Sorb 2800P |
Product Description
V-Sorb 2800P surface area and pore size distribution analyzer parameters
Analysis Method: static volumetric nitrogen adsorption
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
Measuring Ranges: 0.005m2/g to no known upper limit(specific surface area); 0.35 to 500nm (pore size)
Accuracy: repeatability errors less than 1.5%
Vacuum System: V-sorb unique assembling-installed manifolds and electromagnetically operated valve control system, enhance pore size distribution analysis resolution; decrease connecting points; strengthen sealing performance and prolonged instrument life
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 controller electromagnetically operated valve system.
Sample Ports: 2 samples analyzing and 2 degassing concurrently
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)
Transducer Accuracy: imported silicon thin film 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%)
Partial Pressure: P/Po controllable accuracy range is 5x10-6-0.995
V-Sorb 2800P surface area and pore size distribution analyzer features
A: Vacuum System
1. Unique integral manifolds system, decrease connecting points apparently, reduce leak rate, improve ultimate vacuum.
2.Germany imported bipolar vacuum pump, ultimate vacuum can reach 4x10-2Pa (3x10-4Torr).
B: Control System
1. Industry used programmable controller electromagnetically operated valve system, strong anti-interference ability, convenient for installation and uninstallation.
2. Separated analysis and treatment manifolds can prevent foreign matter to contaminate manifolds in sample treatment.
C. Measures for Improving Accuracy
1. Imported silicon thin film capacitive pressure transducer, accuracy can reach 0.15% of real reading, better than 0.15% of F.S. (full-scale).
2. 0-10Torr (optional) and 0-1000Torr dual transducers, sectional measurement in pressure range can reduce errors in low vacuum, 0-10Torr silicon thin film transducer.
