Dr. Ioannis Daniilidis attended the 5th International Glow Discharge Spectroscopy Symposium (5th IGDSS 2022 – hybrid symposium) which took place at Oviedo, Spain on 6th-8th April 2022. More than 150 attendees participated to the specialized conference of Glow Discharge (GD) Spectroscopy. The symposium covered a range of applications for the characterization and study of materials, deploying either Optical Emission (GD-OES) or Mass Spectroscopy (GD-MS). Analytical benefits through a fast, sensitive and precise and characterization of surfaces and depth profile were presented in the three-day sessions. Advances made in the instrumentation and the novel applications were discussed with leaders in the field.
