AI Thread Summary

The discussion centers on the challenges of measuring mesoporous materials and the transition to working with Metal-Organic Frameworks (MOFs). Participants express a lack of deep understanding of the testing methods and data interpretation, primarily using existing measurements for comparative purposes. The conversation highlights the need for effective software and equipment to streamline the measurement of surface area and pore volume in MOFs. One participant has made progress by adjusting the p/p0 range but seeks a more efficient solution to avoid manual calculations for each new material. The mention of Anton Paar's system indicates a search for advanced alternatives in the market to enhance measurement accuracy and efficiency.

TL;DR Summary: My lab is trying to apply BET SA to microporous materials (MOFs, Zeolites) - this doesn't work! I don't have the background to recommend a diff. approach or diff. equipment and I need help.

We've been measuring mesoporous material for years, but no one has the background to really dissect what the test does or what data is results in. We mainly just use it for comparisons.

We are newly working with MOF and trying to measure their surface area and pore volume. I've become our new expert after two hours of reading, but I just don't have the background to know what software/equipment/approach might work better. I've decreased our p/p0 range and seem to be getting okay results but I don't want to puzzle it out manually for every new material we screen.

I know Anton Paar has a system to get around this, but do you or another company have a better answer?
