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 ...

Subtracting Interferences in X‐Ray Spectra Obtained With Grating Spectrometers

X-Ray Spectrometry, EarlyView.
ABSTRACT Higher order diffraction from surface contamination poses a major challenge for soft x‐ray spectral analysis using reflection zone plate spectrometers in electron probe microanalysis. We developed two correction methods applied to the Al L2,3 and Zn M2,3 emissions in AlZn60 alloy spectra: sequential overlay and subtraction of C Kα and O Kα ...

The Stripping Method for X‐Ray Spectral Correction in ISO 4037‐1 Narrow Spectra Series (N10‐N150)

X-Ray Spectrometry, EarlyView.
ABSTRACT Spectrometry is an important tool for the characterization of X‐ray beams in ionizing radiation metrology. However, the use of solid‐state spectrometers for accurate measurements requires correction of spectral distortions caused by the interaction between photons and the detector.

Toward Silica‐Free Compliance: A Low‐Viscosity Sample Pretreatment Methodology for Crystalline Quartz Quantification in Viscous Pastes

X-Ray Spectrometry, EarlyView.
ABSTRACT Crystalline quartz, the most common crystalline silica polymorph, is widely found in industrial products. It is of high regulatory relevance, because its fine fraction, a form of respirable crystalline silica, is classified as an occupational carcinogen, with product‐content thresholds (e.g., 0.1% (w/w) in the European Union) and stringent ...
