IGC Symposium 2021

10th International IGC Symposium on 15 June 2021

The Art of Molecular Surface Sensing by Inverse Gas Chromatography

The 10th IGC symposium focuses on effective and valuable surface characterization of powders, fibers and plates based on the dynamic adsorption of up to 20 different gas probes, also known as Inverse Gas Chromatography (IGC). 

Key objective of the symposium is the exchange of practical experiences and ideas of users. This covers many applications, but also underlying theoretical aspects and the ongoing round-robin results of more than 12 organizations.

The Art of Molecular Surface Sensing by Invers Gas Chromatography was chosen as this year’s caption to highlight the more subtle aspects of IGC, especially the use of different concentrations ranging from ideal single probe molecule adsorption to full surface coverage and adsorption isotherms.

The presentations will cover

  • Many practical applications of surface characterizations by IGC
  • Some theoretical aspects of IGC
  • Experiences of the round-robin tests
  • Q&A sessions

This year the IGC Symposium will be online again. We decided to offer it free to all participants. Join the symposium from anywhere in the world.

Who should attend

The program is compact and ideally suited for industry representatives from R&D, product development and analytical departments as well as researchers from academia interested in real use of IGC.

A brief introduction into IGC as an analytical technique will be given before.
