“…The use and applications for XRF have been reviewed in numerous books and journal papers, including the extensive annual reviews in the Journal of Analytical Atomic Spectrometry (West et al . , , ). A recent book (Croudace and Rothwell ) discussed the use of micro‐XRF for analysing sediment cores, covering the history, its applications and the technical issues related to its use.…”

This GGR biennial critical review covers developments and innovations in key analytical methods published since January 2014, relevant to the chemical, isotopic and crystallographic characterisation of geological and environmental materials. In nine selected analytical fields, publications considered to be of wide significance are summarised, background information is provided and their importance evaluated. In addition to instrumental technologies, this review also presents a summary of new developments in the preparation and characterisation of rock, microanalytical and isotopic reference materials, including a précis of recent changes and revisions to ISO guidelines for reference material characterisation and reporting. Selected reports are provided of isotope ratio analyses by both solution-nebulisation MC-ICP-MS and laser ablation-ICP-MS, as well as of radioactive isotope geochronology by LA-ICP-MS. Most of the analytical techniques elaborated continue to provide new applications for geochemical analysis, however it is noted that instrumental neutron activation analysis has become less popular in recent years, mostly due to the reduced availability of nuclear reactors to act as a neutron source. Many of the newer applications reported here provide analysis at increasingly finer resolution. Examples include atom probe tomography, a very sensitive method providing atomic scale information, nanoscale SIMS, for isotopic imaging of geological and biological samples, and micro-XRF, which has a spatial resolution many orders of magnitude smaller than conventional XRF

“…Various analytical methods have been developed by using X-rays that interact with substances such as transmission, scattering, reflection, and so on. For example, X-ray fluorescence (XRF) analysis of a nondestructive method enables the elemental analysis under atmospheric conditions [1,2]. One of the characteristics is that X-ray imaging analysis called an XRF imaging method can obtain a two-dimen-sional element distribution by using X-ray optics [3].…”

We developed a full-field X-ray diffraction (FFXRD) imaging method using a straight polycapillary realized in the laboratory that can obtain X-ray diffraction (XRD) images with a large area in a short time throughout the simple process without the synchrotron radiation facility. The FFXRD imaging instrument can obtain the XRD images of several millimeter sizes in several hundreds of seconds at each lattice plane. The positional resolution and the spatial resolution was improved by using a straight polycapillary with long type. The FFXRD imaging instrument was attached to the heat treatment system and Cu plate was heat-treated at 300°C. As an example of in situ monitoring of the change in the crystal structure distribution, a high-temperature oxidation process of Cu was observed. The XRD images of Cu, Cu2O, and CuO at each lattice plane were obtained every hour. While the crystal structure distribution of Cu was reduced, the crystal structure distribution of Cu2O and CuO were increased with the oxidation process of Cu by the heat treatment. The change of the crystal structure distribution near the surface by the oxidation process of Cu was confirmed. The XRD image obtained by the FFXRD imaging instrument was analyzed by micro-XRD measurements and confirmed that the FFXRD imaging instrument can accurately obtain the crystal structure distribution. In order to obtain the XRD image with a large area, the FFXRD imaging instrument that can be realized in the laboratory has advantages regarding the exposure time of X-rays and in situ analysis.

“…The latter technique provides detailed information on elemental chemistry such as oxidation state and molecular geometry [72,73]. Based on the energy region of interest, XAS can be further differentiated into X-ray absorption near-edge structure, extending from the pre-edge region to approximately 50 eV above the absorption edge and extended X-ray absorption fine structure (EXAFS), extending from about 50 to 1000 eV beyond the edge.…”

Elements play an imperative role in the physiological and metabolic processes of the human body. When elemental levels deviate from physiologically accepted levels due to for example poor nutrition, the body's intricate elemental and metabolic balance is disturbed. Over time, disease may develop as a result of elemental dyshomeostasis or alternatively, disease may trigger elemental dyshomeostasis as an adaptive metabolic response to an unhealthy environment. There is now a growing interest in screening human tissue to identify and quantify elemental changes as biomarkers of disease or alternatively, as outcomes of disease. The unique properties of human hair brand it the ideal substrate for the quantitative identification of elements in the body. Hair bioaccumulates elements, provides a historical overview of elemental status depending on length, and is easy and economical to sample and store. The fundamental outcome and application of hair elemental screening, however, are strongly influenced by a range of factors, including choice of analytical method. This chapter will provide a background summary of ion beam and synchrotron radiation techniques and its diverse applications for unraveling the elemental signature of hair in various fields.
