X-ray fluorescence trace element analysis using synchrotron radiation.

Present Status of X-ray Fluorescence Analysis of Trace Elements Using Synchrotron Radiation

Synchrotron 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...

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 ...

Correlative 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...
