Basics of Surface Area and Porosity Workshop

INTRODUCTION:
Are you seeking to understand and quantify the ‘surface area’ and porosity of your materials? Then join us for a comprehensive free one-day workshop dedicated to exploring physisorption and its interaction with the surface chemistry of materials.

This workshop combines theoretical insights with hands-on experience to provide a well-rounded understanding of this essential method. Participants will gain valuable skills in physisorption, including practical lab techniques, correct sample preparation, method development and data analysis.

WHY ATTEND? - KEY TAKEAWAYS:
• Fundamentals of physisorption: a clear understanding of what gas physisorption measures - surface area, pore volume & pore size distribution
• Instrument operation: acquire hands-on experience in preparing samples, degassing, method development and conducting physisorption measurements.
• The ability to choose the right probe gas and method - nitrogen vs argon vs CO₂
• Software handling: learn how to navigate current software features and workflows for data analysis, report generation, and leveraging tools to derive meaningful insights from your experiments
• When BET is appropriate - and when it isn’t
• When DFT models outperform classical methods
• Confidence in interpreting isotherms - recognising pore types and structural features
• Identifying measurement artefacts
• Understanding hysteresis and capillary condensation
• Practical competence in data analysis - selecting the correct BET linear region
• Troubleshooting and best practices: avoiding common pitfalls (e.g., forced fits, incorrect degassing)

WHO SHOULD ATTEND:
• Researchers and scientists in material science, chemistry, and related fields
• Industry professionals involved in surface analysis and material characterisation
• Laboratory technicians and quality control specialists

WORKSHOP FORMAT:
The workshop will be delivered in-person by our application and product specialists. Lunches and coffee breaks will be provided by Anton Paar UK. Each participant will also receive a copy of the IUPAC Technical Reference on Physisorption of Gases.

AGENDA:

09:30am: Registration, Coffee and Welcome
09:45am: Foundations of Gas Physisorption

• What is physisorption (vs chemisorption)
• Physical forces involved (van der Waals, pore filling, multilayer adsorption) 
• BET theory: assumptions, linear region selection, C constant interpretation
• Why nitrogen, argon, CO₂ and krypton as probe gases – which one and why?
• Overview of IUPAC pore size classifications
• Langmuir model: when it applies and when it misleads
• t‑plot, αs‑plot, and DR/DA methods for microporosity, BJH, NLDFT, QSDFT for pore size distribution
• Choosing the right model for the right material

10:00am: Instrumentation & Measurement Principles

• Types of physisorption instruments (volumetric)
• Sample preparation: degassing strategies, temperature control, avoiding artefacts, analysis development
• Measurement conditions: relative pressure, equilibrium criteria, cryogen selection
• Understanding isotherm collection and data quality indicators

10:45am: Break
11:00am: Lab Hands-on: Sample Prep, Degassing, Measurement Setup & Development
12:30pm: Lunch
01:15pm: Isotherms & Their Interpretation

• The IUPAC isotherm types and what they reveal
• Hysteresis loops and pore structure implications
• Identifying microporous, mesoporous, and macroporous behaviour
