V-Sorb 2800TP surface area and micropore system parameters

Analysis Method: static volumetric nitrogen adsorption principle

Versatility: Adsorption and desorption isotherms, Single and multi-point BET surface area, Langmuir surface area, Average particle diameter estimation, T-plot external surface area, True density analysis, BJH 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.

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

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

Measuring Ranges: 0.01m2/g to no known upper limit(surface area), 0.35 to 2-500nm (pore size)

Accuracy: repeatability errors ≤1%

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

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

Sample Ports: two samples’ analyzing and two samples’ degassing concurrently

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

Pressure Measurement: imported sectional measuring dual pressure transducer, notably improve the measuring accuracy at low P/Popoint, 0-1000Torr, 0-1Torr and 0-0.1Torr three transducers are equipped

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%)

Vacuum Pump: built-in bipolar vacuum pump controlled by patented software which can auto control pump’s start/stop

DewarVessel: imported 4 liter metal made Dewar can provide at least 72 hours of unattended measurement without refilling the Dewar

Partial Pressure: P/Pocontrollable accuracy range is 5x10-6-0.998

Ultimate Vacuum: bipolar pump: 4x10-2Pa (3x10-4Torr), molecular pump: 5x10-6Pa

Sample Types: powders, particle, fiber, flakes and other materials

Adsorbate Gas: high purity nitrogen (≥99.999%), Ar, Kr, CO, CO2, C4H10 etc. non-corrosive gases are optional

Data Reduction: Windows®-based independent developed Gold APP softwareTM, perfect versatility, produced full featured and multi-model reports
