Compost salinity assessment via portable X-ray fluorescence (PXRF) spectrometry [PDF]

Waste Management, 2018
Compost salinity is an ongoing concern for compost producers, especially with certain feedstocks and in arid or semiarid regions. Current testing protocols call for sampling and testing ex-situ via 1:5 (w/v) slurries via electrical conductance.

pXRF: a study of inter-instrument performance

Journal of Archaeological Science, 2012
Abstract Integrating portable X-ray fluorescence (pXRF) instrumentation into archaeological investigations has generated as much interest as skepticism because several characteristics of the technique limit analytical accuracy and precision. This paper seeks to explore inter-instrument performance in order to assess the potential pXRF instrumentation

Uncertainty and pXRF Measurements

2022
Uncertainty for laboratory instrumentation adheres to the general guide for uncertainty in measurement (GUM). However, portable X-ray fluorescence technology does not lend itself comfortably to the GUM framework for two reasons: calibration models are often kept proprietary by manufacturers and uncertainty is needed on single observation measurements ...

Qualitative Analysis Using pXRF

2022
This 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 on printed circuit boards: Methodology, applications, and challenges

Waste Management, 2022
In 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.
