The missions of the future GDR in mass spectrometry imaging will be first to bring together the different communities, mainly SIMS, TOF-SIMS, tomographic atomic probe and MALDI, WALDI, DESI and LA-ICP-MS, which currently know little about each other, use different tools but have similar scientific questions. This GdR will bring together not only academic laboratories, from CNRS, INRAE, INSERM, CEA, MNHN, but also industrialists, both manufacturers of mass spectrometers and equipment, French or who have representations or subsidiaries in France, but also companies providing analytical services. Organizing training activities in mass spectrometry imaging will also be an important mission of this group. Promoting imaging by mass spectrometry will be a third essential mission, through scientific and training sessions or workshops during or alongside more general conferences in mass spectrometry, but also by seeking the organization in France of major international conferences in this field.
