F-Sorb 2400CE BET Surface Area Analyzer Introduction

The F-Sorb X400CE series surface area analyzers are new generation instruments that be researched and developed by Gold APP Instruments & the Chinese Academy of Ordnance Science.

F-Sorb 2400CE BET surface area analyzer adopts speedy and efficient flowing gas (nitrogen) adsorption principle, is an expert for reference materials comparison method, single and multi-point BET surface area method and Langmuir method analysis. BET method is universally 

recognized and the most commonly used way for nitrogen adsorption surface area analysis. Speedy testing, high cost performances and easy 

operation make F-Sorb 2400CE BET surface area analyzer be a desirable assistant for quality control in production fields, research institutes and universities teaching activities.

F-Sorb 2400CE BET Surface Area Analyzer Specifications

1. Testing Methods: reference materials comparison, single and multi-point BET (Brunauer-Emmett-Teller) surface area, Langmuir surface area, adsorption and desorption isotherm, carbon black external surface (STSA) area, adsorption constant C analysis etc.

2. Measuring Ranges: 0.01 m2/g to no known upper limit (specific surface area).

3. Accuracy: repeatability errors ≤1%.

4. Control Modes: 10 inch display with a built-in mini PC in Win system, also with external keyboard and mouse; external PC is supportable by RS 232 communication port for a larger operation display.

5. Protection Door: transparent door can protect operators be hurt by liquid nitrogen splash, also can reduce liquid nitrogen volatilization, extend analyzing time and save cost; more important is the door can isolate foreign environment influences to the whole analysis procedures, improve data stability and accuracy.

6. Flow Rate Adjust: Gold APP Instruments patented F-Sorb micro stepping motor can realize flow rate auto-adjust for every P/Po point in 

BET (Brunauer-Emmett-Teller) surface area analysis; flow rate value auto-collected by software and real-time displayed in software interface.

7. Quantitative Dosing: patented quantitative pipe desorbs automatically, realized auto dosing for sample desorption isotherm, manual pipelines switch is not required.

8. Manifolds Sealing: high vacuum system with stainless steel manifolds, sound sealing performance can eliminate errors caused by gas 

molecules permeation.

9. Sample Types: powders, particle, fiber, flakes and other species.

10. Sample Ports: 4 samples simultaneously.

11. Analysis Gases: high purity (99.99%) Helium as carrier; Nitrogen (99.99%) as adsorbate; Ar, Kr etc. are optional.

12. Testing Time: less than 5 minutes for every P/Po point, analysis data will present automated on software.

F-Sorb 2400CE BET Surface Area Analyzer Technical Features

Fully automated, farewell to complex manual operation, minimal user intervention.

1. Stainless steel manifold system obviously improves sealing performance, eliminates deviations that be caused by gas molecules permeation, no ageing for manifolds pipelines, increase reliability and prolong instrument working life.

2. Integrated multifunctional control system; motor screw rod lifting system ensures Dewar stability during testing.

3. Innovated balanced bridge circuit greatly improved signal voltage sensitivity, as well as realized auto balance of signal drift.

4. Fully automatic operation, minimal user involvement and work efficiency be improved.

5. High precision data acquisition and signal amplification, high integration A/D transformation system, strong anti-interference ability, all help to reduce environmental influences on analysis procedures.

6. Multi analysis methods, do not need to switch operations frequently, all be set in one interface.

7. Reference materials comparison method and BET surface area method can be switched freely, it simplifies operation steps and improves efficiency.

8. Pioneered gas amount auto-adjust system brings extremely accurate, stable and no user intervention analysis.

F-Sorb 2400CE BET Surface Area Analyzer Application Fields
