Combining XRF and GRT for the analysis of ancient silver coins
2016, Microchemical JournalCitation Excerpt :By calculating the ratio of the Ag–K/Ag–L intensities obtained by one of the fluorescence techniques it is possible to estimate the degree of surface silver enrichment and the error occurring because of it [4,5,9,13,18,20]. Other methodologies are usually based on a combination of several techniques: XRF/EPMA–EDS [4], RBS/PIXE [17], XRF/PIXE/SEM–EDX [18], PIXE/NAA [21], XRF/PIXE/NAA [22,23], and XRF/PIXE/DPAA [24]. However, most of those methods are only aimed at estimating the error or detecting a possible silver surface enrichment and then select the unaffected reliable measurements.
Mitigation strategies for radiation damage in the analysis of ancient materials
2015, TrAC - Trends in Analytical ChemistryAncient materials specifiligaturecities for their synchrotron examination and insights into their epistemological implications
2013, Journal of Cultural HeritageCitation Excerpt :Following an elemental signature from a geological deposit to a gem, an obsidian or a gold artefact may allow to infer its origin and to draw exchange and trade routes of products or semi-products [1,4,36,38]. Historically, early synchrotron analyses of archaeological materials, using XRF, were influenced from PIXE, with trace elemental quantification identified as the major target [39–42]. The concept of trace elemental content is particularly suited to objects distinguishable not so much from their average elemental composition dominated by major elements, but from small deviations from their expected average composition.
Development and trends in synchrotron studies of ancient and historical materials
2012, Physics ReportsCitation Excerpt :The range of synchrotron techniques is very broad and includes hard X-ray, soft X-ray, EUV–VUV, UV/visible, near-, mid- and far-infrared techniques. Although the potentials of the source in the field of ancient and historical materials was identified as soon as the mid 80’s [8–11], real developments started mainly from the years 2000 onwards [12–14] with major contributions from a restricted set of expert users of the technique. The field in some respect still lacks the strong collaborative effort that was put in place in some other fields of synchrotron studies such as for structural biology and nano-sciences.
Characterization of the silver coins of the Hoard of Beçin by X-ray based methods
2011, Nuclear Instruments and Methods in Physics Research, Section B: Beam Interactions with Materials and AtomsCitation Excerpt :Techniques based on the measurement of characteristic X-ray or γ-ray emission, such as EDXRF (energy-dispersive X-ray fluorescence analysis) [1,2], SEM/EDX (energy-dispersive microanalysis in a scanning electron microscope) [3], PIXE (proton-induced X-ray emission) [4,5], SRXRF (synchrotron micro X-ray fluorescence analysis) [6] and NAA (neutron activation analysis) [7], have been widely used in this field. These surface and volume techniques can be combined and/or used complementary [8]. A discussion on the advantages and limitations of these techniques in this field can also be found in the literature [9–11].
