Micro X-ray Fluorescence Spectrometry

Micro X-ray
Micro-XRF performs qualitative analysis of solid samples. Spatially resolved measurements in air or vacuum with confocal (3D) and non-confocal (2D) setup result in elemental maps. Rh (20W) or Mo (50W) X-ray tubes are used to optimize excitation of low-, medium- and high-Z elements. Fluorescence signal is detected using Si(Li) detector. Range of detected elements – from U down to Mg or Na. Scans can be performed with spatial resolution in range of 50µm to obtain 2/3D images, nondestructively.
