• Non-Targeted Screening in Food: Boosting Food Analysis using GC×GC-ToF MS

  Joining us from the University of Messina, Mariosimone Zoccali, Assistant Professor of Analytical Chemistry, present on 'Boosting Food Analysis Using GCxGC-ToFMS. In his talk, Prof. Zoccali explores the pioneering applications of Comprehensive Two-Dimensional Gas Chromatography coupled with Time-of-Flight Mass Spectrometry in the analysis of extra virgin olive oil (EVOO), measured on our newly released Pegasus BTX GCxGC-ToF MS. He shows how this advanced technique provides insights in both targeted and non-targeted analyses , offering deeper understanding into EVOO's chemical profiles. Dr. Zoccali highlights how GCxGC-ToF MS enhances the detection of contaminants and key compounds, such as antioxidants and sterols, which are essential for assessing quality, authenticity and flavor.
