MALDI-TOF mass spectrometric identification of dyes and pigments [PDF]

open access: yesJournal of the American Society for Mass Spectrometry, 2007
We have used MALDI-TOF mass spectrometry to characterize a selection of dyes from the Schweppe dye collection and pigments from the Tate Gallery collection. MALDI-TOF mass spectra of such samples are easily obtained and, through observation of both positive and negative ion spectra, provide a convenient, versatile method for dye characterization and ...

Automatic pigment identification from hyperspectral data

open access: yesJournal of Cultural Heritage, 2018
Abstract Art objects conservation or historical analysis necessitates a thorough knowledge of materials used by the artist and their subsequent changes. In the case of paintings this requires the ability to correctly identify the pigments that were used for creation or later restoration of the artwork.
