The 20th edition of the International GC×GC Symposium will take place from 28 May–1 June 2023, and will be held in Canmore, Alberta in the Canadian Rocky Mountains. Recent developments in GC×GC technology means it has never been easier to get started in this field. The conference starts with introductory and advanced GC×GC courses on Sunday afternoon, and technical content kicks off on Monday morning with the GC×GC Scientific Achievement Award from Ralf Zimmermann. The John B. Philips Award Lecture will be given on Tuesday by Chadin Kulsing. Plenary lectures will be given by Lourdes Ramos on nontarget analysis for persistent organic pollutants by GC×GC, Court Sandau on the use of GC×GC in environmental and forensic science, and Lenny Kouwenhoven, who will describe the first results on a new ASTM D8396 method for petroleum characterization by GC×GC. The rest of the technical programme features talks and posters, covering a range of GC×GC topics including fundamentals and instrumentation, applications in metabolomics, environmental analysis, forensics, foods and natural products, new data processing tools and chemometrics, as well as seminars from leading vendors.
