Webb26 okt. 2024 · Portable X-ray fluorescence (pXRF) can be used to analyze plastic pieces found on beaches. XRF is a form of spectrometry that analyzes the elements in the sample. Energy from the device—radiation—causes atoms in a sample to be excited and emit X-ray photons of characteristic energies related to the element. Webb17 aug. 2024 · Besides being largely used individually, pXRF and pXRD were also combined to investigate a large set of complex geological samples [15]. Coupled pXRF-pXRD analysis delivered both elemental (XRF) and mineralogical (XRD) information of high quality, making it a promising method for the exploration of lithologies, hydrothermal alterations, and ores.
