Webinar Basics of BET specific surface area and pore size distribution evaluation by gas adsorption isotherm measurement

Various functional materials (porous and non-porous) are used in many fields such as environment, energy, pharmaceuticals, and aerospace industries. Therefore, characterization of these materials is essential. In particular, specific surface area and pore size distribution by gas adsorption method are one of the most important data for material development.

In this webinar, we will explain the necessity of adsorption evaluation for each application, outline of adsorption measurement, and analysis method using adsorption measurement based on JIS (z-8830, 8831-2-, 3) and ISO, and provide the correct measurement and analysis method with explanation of terminology for beginners.  Topics

  • What can we learn from nitrogen adsorption isotherm measurement?
  • What is adsorption?
  • What is adsorption isotherm (classification)?
  • Overview of adsorption measurement (Volumetric method, Dynamic flow gas method), free space
  • BELSORP MINI X measurement procedure for the basis of volumetric method
  • BELSORP MR6 measurement procedure for the basis of dynamic flow gas method
