e-SPRESSO Webinar | Is Micropore Characterization Something for Me? Insights from Advanced Physisorption Analysis

For many materials, the BET surface area and mesopore data only tell part of the story. Micropores – the smallest and most selective pore structures – play a decisive role in storage, separation, and catalytic behavior. Yet many researchers still overlook or underestimate their importance due to limitations in conventional surface area analysis. This webinar is designed to directly address the question “Is micropore characterization something for me?”

We begin by revisiting a standard isotherm from a mesopore analyzer collected on a representative carbon or zeolite. Using familiar approaches like BET surface area, t-plot micropore analysis, and DFT pore size distributions, participants will see the type of results typically available to labs relying on mesopore-focused systems.

Next, we compare those results with low-pressure isotherms (in the micropore filling region) obtained using Anton Paar’s Autosorb on the same material. Attendees will see how Autosorb’s improved low-pressure data quality reveals hidden micropore details that mesopore analyzers cannot resolve. The demonstration will show how high-resolution isotherms lead to more accurate BET surface areas, more reliable micropore volumes, and complete pore size distributions.

By directly comparing results across methods, the webinar will demonstrate how advanced micropore physisorption is essential for applications ranging from carbon-based electrodes and gas storage materials to zeolite and drug delivery carriers.
 

Key takeaways for attendees:

• Understand when micropore adsorption data is critical – and when it is not.
• See a head-to-head comparison of mesopore analyzers versus Autosorb micropore analysis on carbon & zeolite materials.
• Learn how BET, t-plot, and DFT analyses differ when supported by high-quality low-pressure data.
• Discover how the Autosorb delivers advanced micropore capabilities for deeper insights into performance, selectivity, and gas storage.

Who should attend:

This session is aimed at researchers and engineers in catalysis, energy storage, porous carbons, zeolites, and pharmaceuticals who are questioning whether micropore analysis is necessary for their work. It is particularly relevant for those currently using mesopore analyzers and considering whether to take the next step into advanced micropore characterization.
