Welcome to the University of Colorado Boulder Electron Microprobe Lab Webpage!

About the Lab

The electron microprobe is the premier instrument for performing non-destructive, in-situ, quantitative chemical analysis of solid materials. EMP surface analyses provide chemical information with a high degree of spatial resolution with analytical volumes as low as 3-5 μm3. Elements ranging from Boron (Z=5) to Uranium (Z=92) can be routinely analyzed with detection limits as low as 50 ppm.

The CU EMP lab welcomes users and collaborations from members of the CU Boulder community, external academic institutions, and private industry.
