Master Surface Characterization: A Masterclass on Physisorption and Chemisorption - Madrid 2026

What You Will Learn

This advanced masterclass will provide a deep, practical understanding of adsorption techniques used in surface and catalyst characterization.

The session is divided into two focused modules:

Masterclass: Physisorption

A critical look at surface area and pore structure analysis.

Topics include:

• Sample preparation fundamentals
  What is the correct degassing temperature?
  Flow vs. vacuum degassing – what’s the difference?
  What really happens when preparation is incorrect?
• The BET equation – beyond the textbook
  How to apply it correctly
  Common mistakes in BET analysis
  Understanding NSA vs. STSA
• Isotherm hysteresis explained
  Why do adsorption and desorption curves differ?
  Interpreting hysteresis loop shapes correctly
• Choosing the right gas
  Nitrogen, krypton, argon, carbon dioxide
  When and why to select each gas
  Handling challenging sample types

Masterclass: Chemisorption

Understanding active sites and catalyst behavior under real conditions.

Topics include:

• TPR, TPO, TPD – similar methods, very different insights
  When to use each technique
  What story each measurement tells
• Proper activation of oxide samples
  Selecting the correct activation temperature
  Impact on metal surface area measurements
• Reversible weak chemisorption
  What it is
  How to measure and interpret it
• Structural changes under reaction conditions
  Does pore size change during chemical reactions?
  Investigating coking and structural evolution
  Cycling between physisorption and chemisorption modes

Who Should Attend?
