pXRF on printed circuit boards: Methodology, applications, and challenges
Waste Management, 2022In order to develop methods to determine the chemical composition of Waste Printed Circuit Boards (WPCB), this study focused on the analysis of 10 metals (Cu, Fe, Sn, Zn, Pb, Ni, Sb, Cr, Mo and Pd) using portable X-ray fluorescence (pXRF) compared to ICP-MS measurements after aqua regia digestion.

Qualitative Analysis Using pXRF
2022This chapter overviews aspects of qualitative and semi-quantitative analysis by XRF from the perspective of paintings and pigment analysis. We review concepts of peak identification, measurement optimizations, data normalizations, and the advantages and limitations of using XRF for the analysis of compositionally heterogenous materials.

pXRF application in soil science
2022Nowadays, when soil pollution poses a worrisome threat to humanity, the need for soil protection is very pronounced with increasing requirements for methods that can quickly and accurately detect pollutants in the soil, especially metals. Portable X-ray fluorescence (pXRF) imposes itself as method with real-time and simultaneous multi- (total) element ...

Tropical Soil Toposequence Characterization via pXRF Spectrometry
Soil Science Society of America Journal, 2019Variability of elemental composition in a toposequence of quartzite‐derived soils in a tropical environment was evaluated via portable x‐ray fluorescence (pXRF) spectrometry. The toposequence featured different degrees of weathering and variable soil formation processes.

pXRF Analysis of Heritage Glass
2022In this chapter, I consider the potential for using pXRF for the analysis of heritage (archaeological and historical) glasses. In the first section of this chapter, I discuss protocols, limitations and weaknesses, best practices, and the possibilities of pXRF analysis of glass. I follow this with a discussion of calibration issues.
