X-Ray Fluorescence Analysis of Gemstones
The energy dispersive X-ray fluorescence analysis (ED-XRFA) is a well-established tool for multielement composition analysis in different fields/1/. It works non-conducting and it is non-destructive. No particular sample preparation is necessary if the specimens have an almost planar and smooth surface. For the characterization of precious gemstone material it is also important that the deposit...
متن کاملFusion Monitors For X-Ray Fluorescence X Analysis
Modern analytical laboratories require tools to assess uncertainties at every step of the analytical process. Borate fusion combined with X-Ray fluorescence has often been demonstrated to be essential for the determination of major elements in cements, ores and a large number of other matrixes. However, drift and bias contributions from the fusion technique, burner position, fluxer to fluxer, m...
متن کاملMultielement analysis of soft drinks by X-ray fluorescence spectrometry.
Several commercial soft drinks and respective plastic bottles were analyzed for their multielement contents employing the synchrotron radiation total reflection X-ray fluorescence spectrometry technique (SRTXRF). The SRTXRF method has been developed and validated, and about 20 elements were detected in the investigated samples, including some trace elements, which can be toxic for human beings,...
متن کاملAn Introduction to X-Ray Fluorescence (XRF) Analysis in Archaeology
As I have discussed in the last chapter, our goal here is not to elucidate XRF for the entire scientific community – this has been done admirably by others – but to translate the physics, mechanics, and art of XRF for those in archaeology and geoarchaeology who use it as one of the many tools to explain the human past in twenty-first century archaeology. While not a simple exercise, it has util...
متن کاملAnalysis of Limestones and Dolomites by X-ray Fluorescence*
Calcium carbonate and calcium-magnesium carbonate in the form of limestone, dolomite, marl, chalk, and Oyster shell are one of the most widely utilized non-metallic materials in the industrial world. The largest use of limestone or calcium carbonate is in the cement industry where it is used as a source of CaO and also in the concrete industry where it is used as the primary coarse aggregate. F...
