ACESSS = Academic Center of Excellence in Separation Science and Sensing

The University of Liège is home to leading research groups in Separation Science and Gas Sensing. To consolidate our strengths in Analytical Chemistry and to streamline ULiège know-how, manpower, instruments, and infrastructures, the Academic Center of Excellence in Separation Science and Sensing (ACESSS) was established. ACESSS aims to reach a higher level of performance and promptly respond to a rapidly evolving and chemically complex world.

ACESSS brings together 5 distinguished research groups, each focusing on advanced analytical techniques such as (ion mobility-) mass spectrometry hyphenated with GC and LC for environmental contaminants, comprehensive GC´GC either or not coupled to LC for the characterization of small molecules, volatolomics, metabolomics, secondary metabolites and food contaminants, and chemical gas sensing among other applications.

ULiège-ACESSS focusses on two main interconnected pillars:

1. Research and development
  • Emerge as a key player in the field of Analytical Chemistry in Europe, thereby enhancing competitiveness for national and international funding programs;
  • Develop groundbreaking research themes and exceptional analytical tools enhancing ULiège-ACESSS visibility.
2. Service to the society
  • Form a task force capable of swiftly responding to any request from society (e.g., environmental or food safety);
  • Strengthen the educational aspects to third parties through tailormade courses, trainings and informative events;
  • Provide tailor-made solutions to stakeholders and society.
