Electron Microprobe Facility

The electron microprobe in the Department of Earth and Space Sciences is a JEOL 733 Superprobe.  This instrument combines four wavelength dispersive spectrometers (WDS) and one energy dispersive spectrometer (EDS) with scanning electron microscope (SEM) capabilities to create an extremely powerful, yet easily accessible, micro-analytical instrument.  

 

The WDS system has diffracting crystals capable of producing quantitative analyses of the elements boron (Z=5) through uranium (Z=92).

 

We use the GELLER dQant-dPict automation and imaging programs. The dPict imaging system can be used to acquire and digitize backscattered (BSE) and secondary electron (SE) images. It is also integrated with the microprobe stage motors and can very easily produce large area (very low magnification) mosaic images of entire thin sections (BSE, SE).
