Alongside XRF mapping, µMEX will offer X-ray microspectroscopy capabilities throughout an energy range (~2.1 – 13.6 keV) and with a spatial resolution unique within the facility and uncommon worldwide. The instrument design enables studies of a wide range of elements and edges, including K-edges of first-row transition metals and s-block elements like sulfur, L-edges for rare earth elements and M-edges for high Z elements like lead and uranium. Though the primary analytical purpose of µMEX is X-ray microspectroscopy, access to energies below 5 keV makes this instrument useful for mapping the distribution of low Z species like chlorine or phosphorous.
