Portable, Benchtop and Micro‐XRF in Agriculture—Present and Future From the Hardware Perspective

X-Ray Spectrometry, EarlyView.
ABSTRACT X‐ray fluorescence (XRF) spectrometry has been an important tool in agricultural studies recently. This technique allows the multielemental, direct, and in situ analysis. The objective of this review is to evaluate the use of XRF in agriculture focusing on plant and soil samples based on indexed articles in the Scopus database from 2020 to ...

Quality from Kent: Preliminary results from the analysis of fifth‐ to seventh‐century silver alloys

Archaeometry, EarlyView.
Abstract This paper explores early results from the chemical and lead isotope analysis of 30 silver‐alloy objects from southeast England dating between the fifth and seventh centuries CE, presenting limited aspects of the three main analyses that were conducted. First, a comparison of the results gained from surface x‐ray fluorescence (pXRF) values and

Uranium, thorium, and potassium analyses using pXRF spectrometry

, 2021
The application of portable XRF spectrometry (pXRF) for determining concentrations of uranium (U), thorium (Th) and potassium (K) was evaluated using a combination of 12 Certified Reference Materials, 17 Standard Reference Materials, and 25 rock samples collected from areas of known U occurrences or mineralization. Samples were analysed by pXRF in Soil,

The Provenance of Silver in the Viking‐Age Hoard From Bedale, North Yorkshire

Archaeometry, EarlyView.
ABSTRACT The acquisition of silver was a key motive propelling the Viking expansion out of Scandinavia; identifying the sources of Viking silver during the early part of the Viking Age can provide critical insights into the relative significance of western European and eastern, Islamic wealth in the Viking expansion.
