The SSA-4000 series of specific surface area and aperture analyzers produce specific surface area and porosity results quickly and reliably, and the analysis station and degassing station are independent and integrated, saving laboratory space. SSA-4000 series is one of the indispensable tools in material research and quality control with low operating cost, fast analysis speed, simple use and good reliability.
Intelligent Degassing System
Integrated intelligent degassing system, 3-station AI intelligent degassing station, equipped with independent vacuum system, degassing station and analysis station can run synchronously and asynchronously to improve work efficiency. Provide "standard", "ultra-light", "multi-water" and other modes of one-click selection, intelligent judgment of the treatment effect.
"Fixed Point" and "Constant Pressure" Tests
Arbitrarily set the test pressure range and the number of data points in the test range to shorten the test time. Freely set any P/Po test point, greatly improve data stability.
Exclusive Test Template Settings
In addition to the standard analysis mode of the software, users can customize the test template according to the sample type and call it with one click. It also supports automatic retrieval of analysis parameters from test reports.
Test theory:
Adsorption and desorption isotherm Gas adsorption curve BET specific surface area measurement Langmuir specific surface area BJH method mesoporous pore volume distribution.
HK/MP/SF method Microhole analysis DR Method Microhole analysis of specific surface area inside and outside t-plot t-plot microhole analysis.
Applications
AI intelligent degassing station to solve the problem of sample preparation
