Introduction to physisorption

Introduction to Physisorption introduces the fundamental concepts of gas adsorption and how adsorption measurements are used to characterize the surface area and pore structure of solid materials.

Throughout this course, learners will explore the principles of physical adsorption, adsorption isotherms, BET surface area theory, pore size analysis, and the calculations commonly used in gas adsorption measurements. The course also explains the importance of sample preparation, degassing, relative pressure, and adsorption behavior in porous materials.

Topics covered include:

• Fundamentals of gas adsorption and physisorption
• Adsorbates and adsorbents
• Sample degassing and preparation
• Adsorption isotherms and relative pressure
• BET surface area analysis
• t-Plot analysis
• Kelvin equation and pore size calculations
• BJH pore size distribution
• Isotherm classifications and hysteresis behavior

This training can be completed at your own pace. You may start, pause, and resume the course at any time until all lessons are complete. The course concludes with a short knowledge assessment.

By the end of this course, you will be able to:

• Understand the principles of physical adsorption
• Explain how adsorption isotherms are generated
• Describe BET surface area calculations
• Identify different isotherm types and pore structures
• Understand pore size distribution methods such as BJH
• Recognize the importance of proper sample preparation and degassing
• Interpret common adsorption analysis results

Upon successful completion, you may print your certificate.
