Historical Textile Dye Analysis Using DESI-MS
Desorption electrospray ionization mass spectrometry (DESI-MS) is an ambient mass spectrometry technique that shows great potential for the analysis of fragile heritage objects in situ. This article focuses on the application of a recently built DESI source to characterize natural dyestuffs in historical textiles and a presentation of initial imaging...Sandström, Edith ; Vettorazzo, Chiara ; Mackay, C Logan ; Troalen, Lore G ; Hulme, Alison N

Development and Application of Desorption Electrospray Ionization Mass Spectrometry for Historical Dye Analysis
A desorption electrospray ionization (DESI) source was built and attached to a Bruker 7T SolariX FT-ICR-MS for the in situ analysis of 14 early synthetic dyestuffs. Optimization using silk and wool cloths dyed with rhodamine B concluded that when using a commercial electrospray emitter (part number: 0601815, Bruker Daltonik), a...Sandström, Edith ; Vettorazzo, Chiara ; Mackay, C Logan ; Troalen, Lore G ; Hulme, Alison N

An optimised small-scale sample preparation workflow for historical dye analysis using UHPLC-PDA applied to Scottish and English Renaissance embroidery
A sample preparation workflow for historical dye analysis based on 96 well plates and filtration by centrifugation was developed. It requires less sample and the introduced error is decreased, making it useful for culturally important objects. A sample preparation workflow for historical dye analysis requiring less sample has been developed....Sandström, Edith ; Wyld, Helen ; Mackay, C Logan ; Troalen, Lore G ; Hulme, Alison N

A multi-analytical approach towards the investigation of Subarctic Athapaskan colouring of quillwork and its sensitivity to photo-degradation
Non-European dyed materials other than textiles have received comparatively little systematic analysis, this is particularly true for objects made with dyed porcupine quills. This paper presents a comprehensive study of a group of Athapaskan porcupine quill specimens collected in 1862 which are held within the collections of National Museums Scotland,...Troalen, Lore ; Röhrs, S ; Calligaro, T ; Pacheco, C ; Kunz, S …

Historical textile dyeing with Genista tinctoria L.: a comprehensive study by UPLC-MS/MS analysis
Polyphenolic components from Genista species have been well characterised because of their potential as antioxidants and as therapeutic leads; however, the identification of dyer's greenweed (Genista tinctoria L.) in historical textiles has been the subject of only limited studies. This paper presents a comprehensive UPLC-PDA MS/MS study of reference and...Troalen, Lore ; Phillips, Ashely S ; Peggie, David A ; Barran, Perdita E ; Hulme, Alison N
