Portable x-ray fluorescence - Open Access .click

Nuclear Instruments and Methods, 1973
Abstract A portable, battery powered X-ray fluorescence analyzer sensitive to a given element within an unknown sample, has been fabricated and tested. The device utilizes an X-ray tube source, balanced filters, dual NaI(Tl) counters, and the electronics necessary to provide instant readout of the presence and abundance of the element in question ...

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.

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 ...
