Spatially resolved mass spectrometry in the study of art and archaeological objects

Spatially resolved mass spectrometry (MS) is a widespread technique increasingly used in many areas of research. Operating in a fast, straightforward way with minimal sample damage, MS investigation can provide spatially resolved information with low limits of detection and a wide linear range. For these reasons, spatially resolved MS is applied in the study of art and archaeological objects, and the current review provides a survey of relevant publications. We highlight the main capabilities and the limitations of spatially resolved MS and discuss the most relevant applications.
