In these studies, wavelength dispersive X-ray fluorescence (WDXRF) was used to examine differences in the elemental composition of agricultural samples, comparing healthy and diseased samples of okra, papaya, and rice. Both the mineral nutrient profiles (macro and micronutrients) and toxic metals were examined, revealing common patterns.

Application of Wavelength Dispersive X-ray Fluorescence to Agricultural Disease Research

Lamellar structures, which are common in many polymeric materials and biological tissues, can diffract X-rays and give rise to reflections at small scattering angles. Analysis of these scattering features can be used investigate the deformation of lamellar structures at the microstructural length.

Small-Angle X-ray Scattering from Lamellar Structures

In X-ray fluorescence (XRF) analysis, physical traceability chains are used to quantify the absolute elemental content in a sample. The physical traceability chain relies on absolute knowledge of the X-ray spectral distribution used for the excitation of the instrument and is currently used at synchrotron radiation facilities. Here, we discuss the transfer of the physical traceability chain to laboratory-based X-ray sources, which are often polychromatic, with the view to generate wider application of quantitative XRF analysis.

Polychromatic and Microfocused X-ray Radiation for Traceable Quantitative X-ray Fluorescence Analysis

In the agrifood sector, soil sampling and analysis is a prerequisite for accurate fertilizer management and to monitor the accumulation of heavy metals in soils. In this study, energy dispersive X-ray fluorescence (EDXRF) was used to analyze soils with variable textures (clay and sandy) and the percent recovery of elements was compared, as a measure of accuracy.

Energy Dispersive XRF in Soil Analysis for the Agrifood Sector

As this study demonstrates, energy-dispersive X-ray fluorescence (EDXRF) and multivariate statistical analysis can be used to distinguish different classes of historical artifacts, such as ancient pottery—revealing insights about theirs origin and uses.
