Micro-XRF is a technique that utilizes X-ray radiation to analyze the distribution of major and minor trace elements in a sample with high spatial resolution. This technique involves directing an X-ray beam onto a small spot on the sample surface, which only irradiates a small portion of the sample. Fluorescence radiation from the sample is then detected using an energy-dispersive detector, allowing for the simultaneous detection of multiple elements over a wide range without any prior knowledge of the sample’s composition. The sample is mounted on a motorized stage, and by moving the sample surface perpendicular to the beam and measuring at many points along a line (line scan) or in an area (area scan), the distribution of elements in the sample can be obtained. This technique is useful for studying a variety of samples, and is particularly effective in analyzing small or complex samples with high precision.
