Description: Wavelength Dispersive X-ray Spectroscopy (WDXRF) is an analytical technique used to identify the elemental composition of materials. This methodology is based on the interaction of X-rays with matter, where the atoms of a material emit characteristic X-rays when excited by a radiation source. The wavelength of these emitted X-rays is specific to each element, allowing for their identification and quantification. WDXRF is particularly valued for its high resolution and sensitivity, making it an essential tool in various scientific disciplines. Through this technique, solids and liquids can be analyzed, and it is capable of detecting elements at very low concentrations. Its ability to provide detailed information about the chemical composition of a sample makes it indispensable in fields such as geology, metallurgy, materials science, and environmental science, where precise elemental analysis is required to better understand the properties and behaviors of the materials under study.
