A quantitative energy dispersive X-ray fluorescence (EDXRF) spectrometry method was developed for determining the concentration of palladium (Pd) applied to tobacco cut filler. Control and standards were created in-house with different levels of Pd concentration. After application of the Pd in a salt solution, the tobacco had an average oven volatiles (OV) value of 27.6%. Three aliquots were an...

Energy-dispersive X-ray fluorescence (EDXRF) spectrometry was previously proposed to measure the thickness of the cellulose nitrate layer of he commonly used LR 115 solid-state nuclear track detector (SSNTD). The present work is devoted to the investigation whether the X-ray radiation nvolved in EDXRF spectrometry will induce degradation of the cellulose nitrate. For this purpose, Fourier trans...

Trace elemental analysis was carried out in 15 anti-epileptic medicinal plants using Energy Dispersive X-Ray Fluorescence (EDXRF) technique, with EX-3600, EDXRF spectrometer. The quantitative analysis is carried out using the software nEXT. The concentrations of elements like P, S, Cl, K, Ca, Mn, Fe, Cu, Zn, Br, Se, Rb, and Sr were estimated. The presence of some of these trace elements is corr...

This study was carried out with the aim of developing the methodology to determine elemental composition in wheat and identify the best germplasm for further research. Orphan and genetically diverse Afghan wheat landraces were chosen and EDXRF was used to measure the content of some of the elements to establish elemental composition in grains of 266 landraces using 10 reference lines. Four elem...

EDXRF spectrometry is used normally to determine the concentration of the different elements in a sample with advantages of good sensitivity, multielemental capabilities, fast, non-destructive and because of this simple relation to the fundamental physics of atom-radiation interaction, make of EDXRF a highly attractive analytical technique. A major goal for research in biomedical sciences over ...

Methodology has been developed for the bulk and trace element analysis of spices such as curry powder and turmeric powder originated from Sri Lanka by the k0-standardization method (INAAk0) and by energy dispersive X-ray fluorescence (EDXRF). SRM 1572 citrus leaves was used to check the accuracy of the results obtained by the two nuclear techniques. The elements determined quantitatively in the...

This paper presents a wavelet-based Gaussian method (WGM) for the peak intensity estimation of energy dispersive X-ray fluorescence (EDXRF). The relationship between the parameters of Gaussian curve and the wavelet coefficients of Gaussian peak point is firstly established based on the Mexican hat wavelet. It is found that the Gaussian parameters can be accurately calculated by any two wavelet ...

A technique to analyze particulates extracted from inline jet engine oil filters using energy dispersive X-ray fluorescence (EDXRF) is presented. This technique, developed by the U.S. Department of Defense’s Joint Oil Analysis Technical Support Center (JOAP-TSC), is termed filter debris analysis (FDA). Six beta prototype instruments capable of performing FDA-EDXRF in an automated mode were manu...

Energy dispersive X-ray fluorescence (EDXRF) is a rapid, straightforward method to determine sample elemental composition. A spectrum can be collected in a few minutes or less, and elemental content can be determined easily if the detector has adequate energy resolution. Radioactive alpha emitters, however, emit X-rays during the alpha decay process that complicates spectral interpretation. Thi...
