Sur la piste des matériaux organiques grâce à la spectrométrie de masse
Identifying the organic materials present, establishing their origin and degree of preservation, understanding their manufacturing process and their use, all of which require interdisciplinary studies involving closely specialists in materials and human sciences. In this very specific context, mass spectrometry has become a key tool to improve knowledge of past civilizations but also to better preserve and restore the discrete remains of archaeomaterials. The identification of diagnostic molecular markers of natural substances is now a recognized strategy for characterizing amorphous organic materials (fats, beeswaxes, vegetable substances such as resins and tars). New advances have also ma…
