F-Sorb 1400 BET surface area analyzer

 Introduction
Using fast and efficient continuous flow method nitrogen adsorption measurement principle , a direct comparison can be specific surface area analysis and testing, the method with the standard sample of known specific surface area of contrast desorption peak obtained directly , without having to physically demarcate the desorbed gas and how much , applies to the standard sample adsorption characteristics similar to the sample tested , mostly for carbon black sample test ; the accuracy of the results because the sample varies, the sample and standard sample adsorption characteristics similar to the high accuracy of the test results , whereas large errors . F-Sorb 1400 is mainly used in the production of live product quality monitoring and rapid determination of the specific surface area .

Features
1 ) Simple and compact appearance design to save space.
2) The all-stainless steel piping systems, improve sealing performance , effectively preventing the penetration of gas molecules than the surface area of the analysis and testing error caused ; and there is no problem of aging stainless steel tube , reliability and life greatly improved.
3 ) the use of advanced control technology, multi-function control system centralized , integrated motor screw lift system , the determination process is more stable than the liquid nitrogen container lifting surface area analysis .

4) The original bridge balance circuit , a substantial increase in signal voltage sensitivity , while achieving signal zero drift automatically balance , is conducive to the determination of the specific surface area analysis automation .
5 ) Complete automation design , the full realization of the specific surface area of intelligent analysis and testing process , without human intervention or guards , greatly reducing the measurement staff workload and improve work efficiency.
