µ-XRF instrument for critical minerals and elements
Micro-X-ray fluorescence spectroscopy (µ-XRF) is a powerful technique that allows for the non-destructive elemental analysis of a wide range of materials.
One of the many applications of µ-XRF is in the characterization of rare earth elements (REEs), a group of seventeen chemically similar elements that have become increasingly important due to their use in various high-tech applications.
The spatial resolution of µ-XRF allows for mapping REE distribution in a sample, which can be particularly useful in mineral exploration and processing. Additionally, µ-XRF can be used to determine the concentration of REEs in various samples, including rocks, ores, and minerals, providing valuable information for developing REE extraction and processing methods. Overall, µ-XRF has become an important tool in characterizing REEs, offering a non-destructive and efficient method for analyzing these valuable elements. With support from the Kempe Foundation, Luleå University of Technology has procured a benchtop µ-XRF (M4 Tornado Plus) to support research and education in the characterization of REEs.
µ-XRF
Micro-X-ray fluorescence (µ-XRF) is a powerful analytical technique that enables scientists to determine the elemental composition of materials with high spatial resolution.
In geoscience applications, µ-XRF can analyse the elemental composition of rocks, minerals, and soils, providing valuable information about underlying formation processes, the distribution of elements in the earth's crust, and contamination in soil samples. In addition, µ-XRF is useful in analyzing the composition of materials, such as metals and ceramics, and in environmental studies, such as the analysis of sediment cores to study past climate conditions.
Overall, µ-XRF is a versatile tool with a wide range of applications in geology, materials science, and environmental studies. With its ability to analyse the elemental composition of materials at the microscale, µ-XRF has many potential applications in several relevant research areas, including critical mineral characterization (REE, graphite, etc.), industrial minerals, and geometallurgical studies.
