Micro X-ray fluorescence spectrometry (µXRF) is a fast, sensitive and non-destructive elemental analysis method for identifying and mapping chemical elements for an array of sample type, including inhomogeneous or irregularly sized specimens. Micro X-ray Fluorescence uses direct X-ray excitation to induce characteristic X-ray fluorescence emission with energy unique to each element of the periodic table providing reliable elemental identification. The instrument uses simple and efficient X-ray optics to restrict the excitation beam to a small spot on the sample surface allowing precise analysis. Owing to its high spatial resolution and little to no sample preparation, µXRF enables fast analyses with high-resolution of large and small samples, and can maps an area of up to 15 cm, with a 25 µm step size which provides rapid screening of trace level elements. MicroXRF is widely used in a wide range of research fields, including geology, metallurgy, materials science and biotechnology to name a few.
