> Test function: Static volumetric principle, adsorption/desorption isotherms measurement, single and multi-point BET method, Langmuir method, t-plot external surface area measurement; BJH total pore volume and pore size distribution analysis, DR and DA filling theory, micropore analysis by HK method, micropore analysis by SF method, micropore analysis by MP method, t-plot micropore analysis, true density measurement; Powerful online data analysis system and specific surface area and pore size distribution test system to ensure more stable and accurate test data. > Test ranges: 0.0005 (m2/g)～unknown upper limit (specific surface area); 0.35 nm - 500 nm, 0.0001 cc/g～unknown upper limit (total pore volume). > Test accuracy: Specific surface area repeatability error ≤±1.0%, the most probable pore size repeatability deviation ≤ 0.02 nm. > Sample number: Four samples were tested at the same time and the four samples' degassing treatment, sample testing system, and sample processing system are independent; > Test modes: Integrated "Single nitrogen test mode" and "Nitrogen + helium standard test mode" for customers to choose according to their actual needs; The "Nitrogen + helium standard test mode" in line with international standards can ensure the accuracy and consistency of results, and is easy to operate; For samples that can adsorb helium at low temperatures, helium gas is not suitable for the determination of free space. The "Single nitrogen test mode" can get the desired test results.
