چکیده

Due to their non-destructive character, X-ray analytical methods are widespread in the field of archaeometry. In the present study, the use of synchrotron radiation induced X-ray fluorescence analysis (SR-XRF) is illustrated on three examples: a silver point drawing of Jan van Eyck, the Hiddensee Gold Treasure, and the Sky Disc of Nebra. The possibility to analyse large objects in normal atmosphere results in information regarding their origin, uniformity, and the manufacturing process. Résumé : Grâce à leur non-destructivité, les techniques analytiques qui utilisent les rayons X sont très répandues dans le domaine de l’archéométrie. L’utilisation de la fluorescence de rayons X induite par radiation de synchrotron (SR-XRF) est illustrée à partir de trois exemples : les dessins à pointe d’argent de Jan van Eyck, le trésor de Hiddensee et le disque céleste de Nebra. L’analyse d’objets, même de grandes tailles, à l’air permet d’obtenir des informations sur leur origine, leur homogénéité et leurs techniques de fabrication.

Micro-sr-xrf and Micro-pixe Studies for Archaeological Gold Identification

For gold, the most promising elements for provenance are Platinum Group Elements (PGE), Sn, Te, Sb, Hg, Pb, but also high melting point elements, such as Ta and Nb. Small fragments of native Carpathian gold placer and primary were studied using Synchrotron Radiation X-Ray Fluorescence at ANKA synchrotron. The goal of the study was to identify the trace elements, especially Sn, Sb and Te. The me...

Nondestructive analysis of silver in gold foil using synchrotron radiation X-ray fluorescence spectrometry.

Small particles of gold foil detached from an indoor decoration might be important evidence to associate a suspect with a crime scene. We have investigated the application of elemental analysis using synchrotron radiation X-ray fluorescence spectrometry to discriminate small particles of gold foil. Eight kinds of gold foil samples collected in Japan were used in the experiments. As a result of ...

Non-destructive characterization of CoTSPc electrochemically deposited on gold electrodes by means of synchrotron X-ray microfluorescence

This paper gives a detailed study of the morphology and heterogeneity of an electrodeposited cobalt tetrasulphophthalocyanine tetrasodium salt (Co(II)TSPc) layer. A continuous potential cycling of the electrode between two potentials can lead to a modification of a bare electrode. During the modification, a non-destructive characterization by means of scanning synchrotron X-ray fluorescence rad...

Quantitative imaging of gold nanoparticle distribution in a tumor-bearing mouse using benchtop x-ray fluorescence computed tomography

X-ray fluorescence computed tomography (XFCT) is a technique that can identify, quantify, and locate elements within objects by detecting x-ray fluorescence (characteristic x-rays) stimulated by an excitation source, typically derived from a synchrotron. However, the use of a synchrotron limits practicality and accessibility of XFCT for routine biomedical imaging applications. Therefore, we hav...
