Sourcing without sources: Measuring ceramic variability with pXRF
Journal of Archaeological Science: Reports, 2018Abstract Sourcing studies usually focus on interpreting movement from source to place of deposition. These studies typically use materials like obsidian that lend themselves to chemical characterization. Less attention has been paid to sourcing materials that are also abundant in the archaeological record such as ceramics.

Compost salinity assessment via portable X-ray fluorescence (PXRF) spectrometry
Waste Management, 2018Compost 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. For this research an alternate approach has been proposed, the use of portable X-ray fluorescence (PXRF ...

Soil horizon delineation using vis-NIR and pXRF data
CATENA, 2019Abstract In this study, we evaluate the use of visible-near infrared (vis-NIR) and portable X-ray fluorescence (pXRF) for delineating soil horizons and how these are affected by soil moisture in a Mollisol (A, Ab, 2E, and 2Bt) profile of south-central Wisconsin.

Elemental assessment of vegetation via portable X-ray fluorescence (PXRF) spectrometry
Journal of Environmental Management, 2018Elemental concentrations in vegetation are of critical importance, whether establishing plant essential element concentrations (toxicity vs. deficiency) or investigating deleterious elements (e.g., heavy metals) differentially extracted from the soil by plants.

pXRF in tropical soils: Methodology, applications, achievements and challenges
2021Abstract Proximal sensors have been increasingly used for a variety of purposes worldwide, with great interest on portable X-ray fluorescence (pXRF) spectrometry applications in Soil Science. pXRF provides rapid, inexpensive, non-destructive, and environmentally-friendly elemental analysis in soils, rocks, sediments, plant tissues, water, and other ...

Handheld Portable Energy-Dispersive X-Ray Fluorescence Spectrometry (pXRF)
2016Handheld portable energy-dispersive X-ray fluorescence (pXRF) spectrometry is used for non-destructive chemical characterization of archaeological ceramics. Portable XRF can provide adequate analytical sensitivity to discriminate geochemically distinct ceramic pastes, and to identify compositional clusters that correlate with data patterns acquired by ...
