X-ray Fluorescence (XRF) News
Scientists at Tokyo University of Science have combined SERS and XRF to distinguish between differently dyed individual hair strands for forensic investigations.
Mass spectrometry, XRF and NIR spectroscopy are being used together with voltammetry to determine the origin of ancient ceramic fragments.
A new sensor fusion technique based on X-ray and 3D imaging promises improvements to the 3D modelling of mineral resources and more efficient sorting of precious metals.
Elemental and isotope analysis of the metals in ancient artefacts such as the prutah shown here sometimes can pinpoint the places where the metal was mined. This can be combined with historical sources to determine when the coin was likely struck. Archaeologists can use the evidence to identify or narrow date ranges of historical significance.
