Soil Sensing With a Handheld LIBS: Effect of Sample Preparation and Instrument Precision
ABSTRACT Rapid and scalable methods for characterising soil elements are needed to understand soil conditions. Handheld Laser‐Induced Breakdown Spectroscopy (LIBS) enables simultaneous multi‐element analysis, but it requires sample preparation by grinding and pelleting, which is challenging for sandy soils due to their poor cohesion.

Compost Cation Exchange Capacity via Portable X-Ray Fluorescence (PXRF) Spectrometry [PDF]
Compost is a valuable organic amendment which affords substantive fertility to soils where applied. A common component of compost fertility is cation exchange capacity (CEC), which has traditionally been determined via standard wet chemistry laboratory ...

The introduction of copper-based metals in Sicily appears to have been a particularly late and slow process. A program of pXRF analyses on early metals in Sicily has revealed the use of mostly copper, and a very late introduction of tin.

Foliar Elemental Analysis of Brazilian Crops via Portable X-ray Fluorescence Spectrometry
Foliar analysis is very important for the nutritional management of crops and as a supplemental parameter for soil fertilizer recommendation. The elemental composition of plants is traditionally obtained by laboratory-based methods after acid digestion ...

The potential of obsidian "big data"
Studies of obsidian provenance have been a core component of the archaeological sciences from the mid-1960s onward. With the growing application of portable X-ray Fluorescence Spectrometers (PXRF) in obsidian research, the number of such studies, and the

An elemental exploration of the metal contents of an early 13th-century craft box from Lõhavere, using pXRF [PDF]
The craft box recovered from a 13thÂ-century hillfort at Lõhavere, Estonia, contained a well-preserved selection of copperÂ-alloy objects. The limited corrosion on these objects allowed a more accurate estimation of their compositions through non ...

pXRF spectrometry in the geoarchaeological analysis of archaeological deposits
Portable X-ray fluorescence (pXRF) spectrometry is widely employed in the geoarchaeological analysis of archaeological deposits. However, the preparation methods and laboratory protocols used remain diverse, with established standards frequently disregarded.

Preliminary exploration using pXRF in the Cassinga region
A study was conducted in the Cassinga region with a portable XRF (pXRF) device to measure chemical elements in soils and rocks. Measurements were made in 318 outcrops and 1638 soils of the area. Four areas part of the Cassinga region were studied: Cuíma-Samboto, Chipindo, Jamba and M’Popo-Tchamutete where chemical elements were reported individually ...

Protocols, pitfalls, and publishing for pXRF analyses: From “know how” to “best practices” [PDF]
Portable X-ray fluorescence (pXRF) exists in a somewhat liminal state as a technique in the archaeological sciences. On one hand, pXRF is essentially energy-dispersive XRF (EDXRF) condensed to fit into a handheld instrument.
