Determination of the Element Distribution in Sauropod Long Bones by Micro-xrf
The distribution of elements in sauropod humeri and femora was determined by micro-X-rayfluorescence analysis (μ-XRF). Element distribution maps enable correlations between bone architecture and spatial distribution of the chemical elements. The investigations reveal no significant macroscopic gradients in the element distribution across the fossil bone cross-section. More detailed investigatio...
متن کاملDepth elemental imaging of forensic samples by confocal micro-XRF method.
Micro-XRF is a significant tool for the analysis of small regions. A micro-X-ray beam can be created in the laboratory by various focusing X-ray optics. Previously, nondestructive 3D-XRF analysis had not been easy because of the high penetration of fluorescent X-rays emitted into the sample. A recently developed confocal micro-XRF technique combined with polycapillary X-ray lenses enables depth...
متن کاملCharacterization of Layerd Materials Related to Forensic Investigation by Confocal Micro-xrf and Atr-ft-ir Imaging Techniques
Micro-X-ray fluorescence (micro-XRF) analysis is a promising method for determining elemental distributions of small regions. Moreover, a recent trend in micro-XRF is 3D elemental analysis by using confocal micro-XRF instruments combined with two polycapillary x-ray lenses. Our research group has been developed confocal micro-XRF instruments by using polycapillary x-ray lenses, and its spatial ...
متن کاملDetermination of the elemental distribution and chemical speciation in highly heterogeneous cementitious materials using synchrotron-based micro-spectroscopic techniques
Synchrotron-based micro-X-ray fluorescence (XRF) combined with scanning electron microscopy-based energy dispersive micro-analysis (EDS) has been used to determine the elemental distribution of contaminants (e.g., Ni) and of chemical elements inherent to the cement matrix (e.g., Si, Ca, Al, S) in hardened cement paste. Detailed information on the cement microstructure was gained by using backsc...
متن کاملGilan Iron Age Diet: Results based on chemical analysis on samples of human and animal bones
Trace element analyses was carried out using Atomic Absorption Spectrophotometer and XRF on a small collection of bones and teeth from horse and human bone samples to check the ratio of strontium and calcium and other elements like zinc and copper. Interestingly the copper representation in humans is much higher compared to that of Sr/Ca. This shows that their diet consisted mainly of animal me...
متن کاملDevelopment of 2D dispersive device for XRF imaging spectrometer
Micro-XRF analysis provides us with elemental maps, which are very useful for understanding the samples under test. Usually, scanning-type elemental mapping is performed. That means, a sample stage is scanned to a fixed X-ray micro beam. XRF analysis is performed at the scanned points, leading to 2D elemental mapping. One of the drawbacks of this technique is the long acquisition time depending...
