JEOL JXA-8230 Electron Microprobe Lab


The department's JEOL JXA-8230 electron microprobe was installed in 2011 and is available for general use; the instrument is located in Bruce Wing, room 122. Clients from academia and industry are welcomed. Services offered include quantitative and qualitative chemical analysis, backscattered and secondary electron imaging, and X-ray mapping. The instrument is equipped with five two-crystal wavelength dispersive spectrometers and one energy dispersive spectrometer (SDD). Among the five WD spectrometers, one contains large-area LiF and PET diffracting crystals, and one contains “high-intensity” LiF and PET crystals. Two spectrometers contain TAP crystals and LDE “pseudocrystals,” the latter for detection of elements of atomic numbers five through nine.
