Portable X-ray fluorescence for bone lead measurements of Australian eagles

Science of The Total Environment, 2021
Lead (Pb) toxicity from ammunition has been shown to be a threat to scavenging birds across the globe. Toxic levels of lead have recently been found in Australia's largest bird of prey, the wedge-tailed eagle (Aquila audax), through inductively coupled plasma mass spectrometry (ICP-MS) analysis of liver and bone samples. However, ICP-MS is consumptive (

Evaluation of Portable X-ray Fluorescence for Gypsum Quantification in Soils

Soil Science, 2009
The use of field portable X-ray fluorescence (XRF) spectrometry as a quantification tool for gypsum content in soils of West Texas and southern New Mexico, USA, was evaluated. Six sites were evaluated with gypsum contents ranging from less than 10% to greater than 90%.

Portable X-ray fluorescence single element analyzer

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 for the analysis of chromium in nail and nail clippings

Applied Radiation and Isotopes, 2017
Assessment of chromium content in human nail or nail clippings could serve as an effective biomarker of chromium status. The feasibility of a new portable x-ray fluorescence (XRF) approach to chromium measurement was investigated through analysis of nail and nail clipping phantoms.

A portable instrument for energy-dispersive X-ray fluorescence analysis of sulfur

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1997
Abstract A simple and portable instrument was constructed, based on the energy-dispersive X-ray fluorescence, for the analysis in situ of sulfur in lapideous materials such as frescoes and stone monuments. Sulfur is generally an index of pollution, and the detection of sulfur is of great importance. The instrument for sulfur analysis is characterized
