Reference-free X-ray fluorescence analysis using well-known polychromatic 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 ...

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

Synchrotron 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...
