Testing principle

Low temperature nitrogen adsorption, flow chromatography method

Method features

***Technology.
Using adsorption peaks, similar to the static capacity method, four samples were tested independently without interference, with sharp signal peaks The testing accuracy of 10m2/g small surface area samples has significantly improved

Traditional detachment techniques.
Using desorption peaks, the four samples are parallel and not independent, and the signal peaks are diluted, which is not suitable for precise testing of small surface area samples with a specific area of less than 10m2/g

Testing function

Comparison method with surface area test;
Single point and multi-point BET specific surface area testing

Test gas

High purity nitrogen (99.999%)+high-purity helium (99.999%)

Range of nitrogen partial pressure P/P0

0.05-0.35 (multi-point BET)

Scope of testing

Specific surface area 0.01m2/G to no known upper limit,
Not suitable for testing microporous materials

Repetitive accuracy

Carbon black standard sample ≤± 1.0%;
Highly consistent with the accuracy of static capacity method testing

Carbon black standard sample ≤± 1.5%;
