Technical advantages
Here is the translation of the additional content you provided:
◆ High Throughput and High Efficiency
Supports analysis of up to 12 samples at once;
◆ True Full Automation
Internationally pioneering automatic switching between degassing furnace and Dewar cup, eliminating the need for manual transfer of sample tubes or degassing furnace;
◆ High Time Utilization
Resolves the time wastage issue of conventional instruments where degassing completes after work hours, preventing the initiation of testing, making it possible to load samples after work and view data the next working day;
◆ Complete Elimination of 'Helium Contamination'
Helium gas test dead volume → vacuum heating degassing → adsorption testing, pioneering the resolution of the helium contamination challenge in micropore analysis within the international scope, enhancing testing accuracy;
◆ Anti-flying Degassing
Supports 'pressure-controlled heating' + 'pressure-controlled vacuum pumping', automatically adjusting programmed heating and vacuum pumping rates based on pressure changes to prevent sample flying;
◆ Supports Automatic Cycling Testing
Automatic degassing + testing cycling for evaluating material adsorption performance stability and adsorption performance lifetime assessment;
◆ 'Pressure-controlled Heating' Sample Pore Protection Technology (Compliant with International Standard ISO 9277:2022)
Programmed heating technology under gas pressure control, automatically starting and stopping programmed heating based on pressure changes to prevent excessively rapid gas release from samples, thereby preventing sample pore damage caused by rapid gas release; (This phenomenon is more common with microporous samples. Once sample pore damage occurs, it is difficult to detect and is one of the important sources of instability in microporous sample test results).
