The electron microprobe is the premiere instrument for performing non-destructive, in-situ, quantitative chemical analysis of solid materials viaÌýwavelength dispersive spectrometry. EMP surface analyses provide chemicalÌýinformation with a high degree of spatial resolution with analytical volumes asÌýlow as 3-5 μm3. Elements ranging from Boron (Z=5) to Uranium (Z=92) can beÌýroutinely analyzed with detection limits as low as 50 ppm. The EML is housedÌýwithin the Department of Geological Sciences. The lab is equipped with JEOLÌý8230 Electron Microprobe. This instrument was purchased in 2017Ìý with an NSFÌýMRI award. The laboratory also contains a Leica ACE600 carbon thin filmÌýevaporation system for the preparation of non-conductive samples.ÌýÌý​​
