This application note describes the texture analysis of a rolled copper specimen. The experimental data were measured on a multi-purpose X-ray diffraction system equipped with a texture cradle.. In polycrystalline solid materials, such as a wide class of metals and ceramics, usually the orientation of the crystallites, constituting the matrial, is not distributed randomly, like in an ideal powder specimen. In most cases a preferred orientation of the crystallites with respect to the sample reference frame is present. In materials science this preferred orientation is referred to as texture. .

This application note demonstrates the performance of the Axios FAST XRF spectrometer for the analysis of Al-Si and Al-Mg alloys.. Accurate and fast elemental analysis during the production process of aluminum and its base materials is a critical requirement. Measurements were performed using an Axios FAST simultaneous X-ray fluorescence spectrometer equipped with a 4 kW Rh SST-mAX X-ray tube. .

To guide soil fertility investment programmes in sub-Saharan Africa, better understanding is needed of the relative importance of soil and crop management factors in determining smallholder crop yields and yield variability. Spatial variability in crop yields within farms is strongly influenced by variation in both current crop management (e.g. planting dates, fertilizer rates) and soil fertility. Variability in soil fertility is in turn strongly influenced by farmers’ past soil and crop management. The aim of this study was to investigate the relative importance of soil fertility and crop management factors in determining yield variability and the gap between farmers’ maize yields and potential yields in western Kenya. In this study, 522 samples taken from the farms were analysed by diffuse reflectance spectroscopy, using an ASD FieldSpec FR spectroradiometer.

Objectives:. (i) to estimate mineralogical composition specifically clay mineralogy from the spectra, (ii) to qualitatively compare mineral concentrations calculated from XRF and XRD analyses, as well as mineral groups identified through SEM and microscopic petrography work with NIR results.. NIR spectroscopy has been widely used in different scientific fields such as biology and medicine. However, it has been rarely used in mineral identification in finer sedimentary rocks specifically mudrocks. This work will allow us to verify the accuracy of this technique compared with XRF and XRD..

This application study was designed to demonstrate the performance of the Epsilon 5 EDXRF spectrometer and to show that the instrument meets the analytical challenge of analyzing Fe, Cu, Ni, As, Cd and Pb in edible oils. The long term stability and precision of the instrument is also demonstrated.. The refining processes for products such as edible oils require the addition of catalysts in the correct proportions to optimize the processing reactions. These catalysts also contain elements such as Ni and Fe that must be removed from the oils during the later stages of the refining process. .

Detection limits for typical medium-power wavelengthdispersive spectrometers (WDXRF) configured for geological applications are illustrated in this application note.. A series of soil and rock standards were used to calibrate the application. The soil samples were analyzed in the form of pressed powder pellets.

This application study demonstrates the performance of the Epsilon 5 EDXRF analyzer according to the EPA method IO-3.3, with the elemental range extended from 44 to 55 elements.. The presence of toxic pollutants in the air has been a subject of research for many years. The measurement of the elemental composition of the particulate matter is a key factor in understanding the long-term health effects of pollution. .
