Technical Parameters   

Test principal: Continuous Flow Chromatography method, Low temperature nitrogen adsorption

Test methods: Direct Comparison method 

Gas: mixed gas of high purity nitrogen and helium (The proportion of nitrogen and helium is 3/7; and gas purity is 99.999%).

Flow control: automatic control program, P / Po 0.05 - 0.35, control accuracy error ≤ 0.5%; 

Measuring range: Surface area ≥ 0.01m2/g, no upper limits;  

Sample NO:  one standard sample and 3 samples tested   

Test Efficiency: Direct comparison measures specific surface area: 15 minutes for three samples

Repeatability Accuracy:  ≤ ±1 %

Data acquisition: high-precision data acquisition and processing chip, high anti-interference ability.

Data processing: WINDOWS-compatible data processing software, completely green without installing, providing multi-mode data analysis, graphical processing interface, real-time monitoring experiment, simple operation.

Control system: The entire testing process is completely automatic. With large volume dewar and liquid nitrogen surface control technology, the whole experiment don’t need add liquid nitrogen.
