Digital x-ray imaging (DXI) has been utilized to display spatial elemental distribution and to conduct quantitative elemental compositional mapping on various samples. The quantitative elemental compositional mapping technique, however, requires the use of an advanced image analysis and computer system to display elemental concentration maps. In this study, a simplified DXI technique is used to achieve two goals: (1) display elemental distribution, and (2) conduct quantitative mineral compositional analysis using stored digital x-ray maps. The analytical procedure of this technique can be easi

Abstract. Geochemical mapping is a fundamental tool for elucidating the distribution and behaviour of economically significant elements and providing valuable insights into geological processes. Nevertheless, the quantification of uncertainty associated with geochemical mapping has only recently become a subject of widespread concern. This study presents a procedure that primarily consists of the determination of homogeneous clusters, the recognition of elemental associations for each cluster, and the identification of geochemical anomalies, with the aim of accounting for the uncertainty of el

Annotation:

The intensity of a characteristic electron energy loss spectroscopy (EELS) image does not, in general, directly reflect the elemental concentration. In fact, the raw core loss image can give a misleading impression of the elemental distribution. This is because the measured core edge signal depends on the amount of plural scattering which can vary significantly from region to region in a sample. Here, we show how the method for quantifying spectra due to Egerton et al. can be extended to maps.

In this study, a technique for reconstructing elemental distribution mapping of trace elements from spectral data was developed. The reconstruction was made possible by using the measured fluorescent signals to obtain local differences in elemental concentrations. Th

Chemical analysis in a TEM has usually been done as a manual point analysis by forming a probe of an appropriate size for the area of interest. This type of local analysis may provide enough information from the selected area, but these days when materials properties are found to be deeply dependent on chemical distribution, one needs to do a higher dimensional analysis using a systematic line scan or mapping.Since the advent of the Field Emission Gun (FEG), chemical mapping using X-rays (EDS mapping) or inelastic scattered electrons (Energy Filtering mapping) has become more and more commonly

A knowledge of the distribution of chemical elements in a specimen is often highly useful. In materials science specimens features such as grain boundaries and precipitates generally force a certain order on mental distribution, so that a single profile away from the boundary or precipitate gives a full description of all relevant data. No such simplicity can be assumed in life science specimens, where elements can occur various combinations and in different concentrations in tissue.

Abstract Background: Metals are not homogeneously distributed in organ tissues. Although most mapping techniques, such as histologic staining methods, have been developed for element imaging on a subcellular level, many suffer from either low precision or poor detection limits. Therefore, small variations in elemental distribution cannot be identified. We developed a method for two-dimensional mapping of trace elements to identify the influence of metabolic zonation by the liver on trace element distribution. Methods: A prepared homogeneous Certified Reference Material (CRM; LGC 7112, pig live

The composition of an annealed ternary system is examined by combined ion beam analysis (standard RBS & nuclear microprobe PIXE), SEM (morphology & EDS) and also with XRD to get the elemental composition and distribution over particular micro regions. The ternary system is built by the superposition of two metal layers, Gold and Copper respectively, both having 1200 Å in thickness, successively deposited on a (111) monocristalline silicon substrate. Then, the whole system is subjected to a vacuum heat treatment (at 400°C during 30 min). The enhanced interdiffusion and the arisen transf

Cross-sections of morphology-controlled catalysts mixed with ionomer are analyzed with energy-dispersive X-ray spectroscopy. The elemental mappings provide information about the behavior of the ionomer on the nanoscale, including the penetration depth of the ionomer into small mesopores. Furthermore, the suitability of metal ion exchange for tracking the ionomer distribution is validated by post-impregnation with cesium. Ultimately, this work lays the foundation for a meaningful characterization of the ionomer distribution in catalyst layers of proton exchange membrane fuel cells.

AbstractA method for the analysis of cathodoluminescence spectra is described that enables quantitative trace-element-level distributions to be mapped within minerals and materials. Cathodoluminescence intensities for a number of rare earth elements are determined by Gaussian peak fitting, and these intensities show positive correlation with independently measured concentrations down to parts per million levels. The ability to quantify cathodoluminescence spectra provides a powerful tool to determine both trace element abundances and charge state, while major elemental levels can be determined

In order to maintain homeostasis and consequent optimal cell functioning and integrity and/or to avoid toxicity, proper allocation of elements at organ, tissue, cellular and subcellular level is needed. Studies of element localization are therefore crucial to reveal the mechanisms of element trafficking and also tolerance and toxicity. Moreover, studies of localization and speciation of trace elements in grains of staple crops are also of high applicative value, allowing one to determine major and trace element concentrations in different grain tissues without possible contamination.

The application of Laser-Induced Breakdown Spectroscopy (LIBS) is presented for the direct elemental analysis of hydrocarbon-rich solids. In recent years, LIBS has become a powerful tool for obtaining elemental information and mapping analysis of different petroleum-rich samples with minimal to no sample preparation and without the need to separate the organic matter from the inorganic matter. By selecting the most intense and representative lines, the element distribution in a 2D map can be accessed in less than ten hours. For this reason, two types of hydrocarbon-rich solids were chosen for

Current understanding of bone healing and remodelling strategies in vertebrates has traditionally relied on morphological observations through the histological analysis of thin sections. However, chemical analysis may also be used in such interpretations, as different elements are known to be absorbed and used by bone for different physiological purposes such as growth and healing. These chemical signatures are beyond the detection limit of most laboratory-based analytical techniques (e.g. scanning electron microscopy). However, synchrotron rapid scanning–X-ray fluorescence (SRS–XRF) is an ele

Fossils, including those that occasionally preserve decay-prone soft tissues, are mostly made of minerals. Accessing their chemical composition provides unique insight into their past biology and/or the mechanisms by which they preserve, leading to a series of developments in chemical and elemental imaging. However, the mineral composition of fossils, particularly where soft tissues are preserved, is often only inferred indirectly from elemental data, while X-ray diffraction that specifically provides phase identification received little attention.

In addition to the reduction of the STEM probe size, a dramatic increase in the STEM probe current has been realized, leading to the routine acquisition of high-resolution elemental and chemical maps using electron energy loss spectrometry (EELS).
