The use of a combination target consisting of an HOPG Bragg crystal and an Al203 Barkla scatterer for the excitation of the elements Na to U represents further progress in the development of using polarized excitation in EDXRP. The high, integrated reflectivity of the HOPG crystal improves detection limits and sensitivities for Na, Mg, Al, Si, P and S-traces in light and heavy matrices in compa...

The accuracy and precision of energy dispersive X-ray fluorescence (EDXRF) improve with improved detector energy resolution. However, there are trade-offs between the highest energy resolution and the highest count rates, and there are practical difficulties in achieving the very best energy resolution. Energy resolution differentiates systems but the benefits of improved energy resolution, in ...

Metal concentrations have been measured in water and sediments of the Jose Antonio Alzate Reservoir, Mexico, using EDXRF and ICP techniques. Spatial and temporal distributions of total metal levels have been identified; no organised pattern was detected for any particular metal concentration. Temporal variations of metal concentrations show evidence of the water self-cleaning capacity of the re...

Energy Dispersive X-Ray Fluorescence (EDXRF) technique has been used to study two Rupee Indian coins minted during the period 1993 to 2010 for their elemental concentrations. From the analysis of the coins, it is found that the coins are made of binary alloy and it was observed that from 2005 onwards, the composition of the coins has been changed from Cupro-Nickel to Ferritic Stainless Steel (F...
