A number of products have entered the testing laboratories of European and American universities and have been highly recognized by customers.
Intelligent testing software
The sample processing function is integrated into the test software to realize the complete automation. Sample processing time, different processing temperature combinations, sample processing delay, and other functions can be set flexibly, which can realize automatic sample processing at night and improve testing efficiency.
Data processing software has perfect functions and easy operation, a user-friendly interface, detailed test data records, and a variety of perfect data processing modes.
The test software adopts Net software development platform of the advanced Microsoft technology with strong compatibility that can automatically be compatible with all and the future windows operating system.
Key Performance Indicators
> 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, true density measurement, DR and DA filling theory, micropore analysis by HK method, micropore analysis by SF method, micropore analysis by MP method, t-plot micropore analysis; Powerful online data analysis system and specific surface area and pore size distribution test system to ensure more stable and accurate testing 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:
EASY-V 3220: simultaneous testing of two samples; EASY-V 3210: alternate testing of two samples.
The two samples' degassing treatment, sample testing system, and sample processing system are independent; sample testing and sample processing can be carried out simultaneously, avoiding the contamination of the test pipeline, further ensuring the accuracy of the test, and improving the service life of the instrument.
> 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.
