Abstract: ) exceeding 0.99 for both PDA and MS detectors. Detection limits (LOD) varied from 0.23 ppm (Crystal violet) to 4.12 ppm (Amido naphthol red G) based on the UHPLC-PDA signal, and from 0.024 ppm (Diamond green G) to 0.65 ppm (Cochineal red A) based on the UHPLC-MS signal. Precision, measured by intra-day relative standard deviation (RSD) values was consistently under 5 % for UHPLC-PDA and under 9 % for UHPLC-MS, while inter-day RSD values were below 13 % for UHPLC-PDA and below 8 % for UHPLC-MS. The method's applicability was further tested on two historical artworks: a tapestry by Lanckaert (1587-1589) from the collection of the Museum De Lakenhal, Leiden, The Netherlands, and a 19th-century hip cloth from Aceh, Indonesia. Results from the case studies underscore the method's effectiveness in identifying complex mixtures of both synthetic and natural organic colourants in a single run using minute sample sizes. Beyond offering critical insights into historical dyeing procedures that support conservation work, the method also enhances the understanding of technological advancements in textile production.
