Recent Advances in Portable X‐Ray Fluorescence Spectrometry

Applied Spectroscopy Reviews, 2004
Abstract X‐ray fluorescence (XRF) spectrometry is a nondestructive, rapid, simultaneous multi‐element analytical methodology for solid or liquid samples. Its applications are broad and XRF spectra cover most elements, with a dynamic range from 100% down to the µg/g level.

X-ray fluorescence analysis of heavy elements with a portable synchrotron

Spectrochimica Acta, Part B: Atomic Spectroscopy, 2004
X-ray fluorescence analysis of heavy elements was performed using a portable synchrotron named MIRRORCLE. Analyzed heavy elements were Pb, Pt, W, Sn, and Ag. The characteristic K X-rays were clearly observed for all the five elements. This verifies that MRRORCLE generates X-rays of energy higher than that of the Pb K absorption edge (88.0 keV).

Portable x‐ray fluorescence spectrometer with a pyroelectric x‐ray generator

X-Ray Spectrometry, 2005
Abstract A portable x‐ray fluorescence spectrometer was assembled with an x‐ray generator that was driven by a 9 V dry electric battery. Several possible optimum geometries of the x‐ray generator and detector were evaluated, and the results showed that the intensity of fluorescent x‐rays was strong enough when the angle between the x ...

Portable X‐ray fluorescence spectrometry analysis of soils

Soil Science Society of America Journal, 2020
Abstract Portable X‐ray fluorescence (PXRF) spectrometry is a proximal sensing technique whereby low‐power X‐rays are used to make elemental determinations in soils. The technique is rapid, portable, and provides multi‐elemental analysis with results generally comparable to traditional laboratory‐based techniques.
