First evidence and characterisation of rare chrome-based colourants used on 19th-century textiles from Myanmar

An Introduction and Recent Advances in the Analytical Study of Early Synthetic Dyes and Organic Pigments in Cultural Heritage

“…On the other hand, the straightforward identification of a compound can be more easily achieved by high-resolution tandem mass spectrometry (HR-MS/MS), whose applications have increased in heritage science in the last decade. In most cases, the chromatographic and mass spectrometric systems are coupled by an electrospray ionisation source and HR-MS/MS is mostly obtained by Q-ToF [37,184] or, more recently, orbitrap mass analysers [185,186]. HPLC-MS/MS has been applied to artworks, including archive and reference paint materials [11,27,37,65,70,187], historical inks [168,181], 19th-20th century textiles [78,79,86,184], modern and contemporary paintings [188][189][190][191][192] and street art murals [193,194].…”
