DVS and iGC: The key methods in investigating vapor sorption properties

Date: Wednesday, 01 July | 13:30 – 15:30 (CEST)

The workshop will cover the Dynamic Vapor Sorption (DVS) and Inverse Gas Chromatography (iGC) methods. The presenters will discuss advanced applications using these methods on studies on permeation and diffusion measurements, porosity and surface area.

Both DVS and iGC-SEA are used for research and development in thousands of laboratories in many universities and industries worldwide. This is a good opportunity to learn more about these methods and also ask questions to leading scientists within the field.

The workshop is beneficial to individuals who want to learn more about DVS and iGC and whose work are in the following industries:

  • Composite
  • Fibres and Fillers
  • Powders and Porous Materials


Session 1: Dynamic Vapor Sorption (DVS) Flow systems

  • DVS Principle and Advanced Applications
  • Camera and Raman
  • Simulation of the DVS control software
  • BET surface area
  • Permeability and diffusion
  • Pores size distribution

Session 2: Inverse Gas Chromatography-Surface Energy Analyzer (iGC-SEA) for Surface Characterization

  • iGC-SEA Principle and Advanced Applications
  • Dispersive and polar surface energies
  • Acid-base interactions
  • Phase transitions
  • Sorption isotherms
  • Permeability, solubility and diffusion
  • Surface energy heterogeneity mapping

At the end of each session, there is an opportunity to ask questions to the presenters.
