Element Analysis Based on Energy-Dispersive X-Ray Fluorescence

Abstract

Energy-dispersive X-ray fluorescence (EDXRF) spectrometry is a nondestructive, rapid, multielement, highly accurate, and environment friendly analysis compared with other elemental detection methods. Thus, EDXRF spectrometry is applicable for production quality control, ecological environment monitoring, geological surveying, food inspection, and heritage analysis, among others. A hardware platform for the EDXRF spectrometer is designed in this study based on the theoretical analysis of energy-dispersive X-ray. The platform includes a power supply subsystem, an optical subsystem, a control subsystem, and a personal computer. A fluorescence spectrum analytical method is then developed to obtain the category and content of elements in a sample. This method includes qualitative and quantitative analyses. Finally, a series of experiments is performed. Results show that the precision of the proposed measurement method is below 8%, whereas its repeatability is below 2%.

Recovering and restitution of unknown, unidentified, and unlabeled samples in laboratories using EDXRF analysis

“…The EDXRF spectrometry [1] , [2] , [3] is a non-destructive nuclear method used to characterize samples in the view of their elemental composition. EDXRF spectrometry is applicable for production quality control, ecological environment monitoring, geological surveying (including the applications of µ-EDXRF), food safety, and heritage analysis, among others [4 , 5] . The method is being used worldwide because of its robustness, fast screening, and the possibility to be used in-situ and with different matrices [6] , [7] , [8] , [9] .…”

Radiation Resistance of a Structural Material Based on Modified Titanium Hydride

“…e analysis software used was GuantAS, UniGuant, and OptiGuant. e XRF method is based on the excitation of the characteristic radiation of different elements in a sample using an external source (X-ray or isotope photon source), and registration of said characteristic radiation in the form of a line spectrum [40]. e position of the peaks in the K, L, and M-series of characteristic radiation on the energy scale is responsible for the identification of chemical elements in the sample, and the intensity of the peaks broadly represents the concentrations of elements.…”

Energy-Dispersive X-ray (EDX) fluorescence based analysis of heavy metals in marble powder, paddy soil and rice (Oryza sativa L.) with potential health risks in District Malakand, Khyber Pakhtunkhwa, Pakistan

“…Energy-dispersive X-ray fluorescence spectroscopy (ED-XRF) is a rapid, non-destructive, and easy handling analytical technique widely used for fast mineral analysis in the cement industry, archeology, mining, geology, forensic and food sciences [19][20][21]. ED-XRF has a specific, multi-elemental detection capacity that involves no sample pre-treatment.…”

“…Generally, elements with higher atomic weight required higher energy for fluorescence emission and subsequently higher energy of fluorescence easily detects fluorescence. The elemental concentration in the analytical sample is estimated by calibration standards that are used to correlate the intensity of emitted X-ray for each element with its previously known concentration already detected via ICP-OES [21,28]. The current study aimed (i) to analyze essential and toxic elements of marble waste powder, and their subsequent accumulation in paddy soil and rice plants (ii) to determine the potential sources of elements in paddy soil, and rice plants through multivariate statistical techniques (iii) and to assess the potential human health-related risks for the local population via the dietary intake of rice grains.…”
