Synchrotron Radiation Based Confocal X-ray Fluorescence and Absorption Microspectroscopy in Earth and Environmental Science
The latest developments in energy-dispersive X-ray detection technology combined with the use of sophisticated X-ray detector optics open new avenues for the determination of 2D/ 3D distribution of (trace) elements within the investigated samples on the microscopic scale. This work illustrates the development and applications of synchrotron radiation based micro-XRF/XAS imaging towards a fully ...
متن کاملSynchrotron radiation-induced total reflection X-ray fluorescence analysis
Synchrotron radiation-induced total reflection X-ray fluorescence (SR-TXRF) analysis is a high sensitive analytical technique that offers limits of detection in the femtogram range for most elements. Besides the analytical aspect, SR-TXRF is mainly used in combination with angle-dependent measurements and/or X-ray absorption near-edge structure (XANES) spectroscopy to gain additional informatio...
متن کاملSynchrotron X-ray Fluorescence Analysis of Dust Particles
Introduction: Synchrotron x-ray fluorescence (SXRF) studies carried out on a microprobe endstation allow non-destructive analysis of both major and trace element abundances in particles only microns in size. The technique has been applied to IDPs captured in the stratosphere to study atmospheric entry effects such as stratospheric contamination and frictional heating [1, 2]. SXRF will also be a...
متن کاملX-ray Absorption Spectroscopy in Mineralogy and in the Earth and Environmental Sciences
Introduction X-ray absorption spectroscopy (XAS) has proven to be an outstanding structural tool by allowing the determination of the local environment around a selected atomic species in a great variety of systems. An important advantage of this technique is its utility for heterogeneous samples in such a way that a wide variety of solid and liquids, including whole soils and liquids, can all ...
متن کاملCorrelative Chemical Element Imaging in Cells Using Fluorescence Microscopy and Synchrotron X-ray Fluorescence
Synchrotron radiation X-ray fluorescence (SXRF) microscopy holds the potential for fundamental breakthroughs in the understanding of biological systems because chemical element distributions can be evidenced at the sub-cellular level (<100 nm) with low detection limits (<100 ng/g). In addition to SXRF, it is also possible to perform X-ray Absorption Spectroscopy (XAS) which is based on the phot...
