Electron Microprobe Laboratory
The Electron Microprobe Laboratory is a campus-wide and regional analytical and imaging facility available to University of California, Davis, students, faculty, and staff, as well as off-campus users.
The centerpiece of our laboratory is a Cameca SX-100 electron microprobe, purchased in 2002 with funds from the National Science Foundation and the UC Davis Office of Research. We can provide training for those who would like to operate the instrument themselves, or we can analyze samples you send to us.
The Electron Microprobe Lab is operated by the UC Davis Earth and Planetary Sciences Department and is located in the Earth and Physical Sciences building.

Analyses and Imaging Capabilities:
- Quantitative analyses from Z = 4 (Be) to 92 (U) uranium
- Special capabilities for quantitative analysis of light elements, Z = 4 (Be) to Z= 8 (O)
- Capability for high resolution elemental mapping and trace element analysis at low concentrations (generally to 100’s of ppm)
- High speed back scattered electron (BSE) imaging
- Transmitted and reflected light imaging
- Automated calibration and analysis
- Wide range of in-house calibration standards for quantitative analyses of silicates, sulfides, carbonates, oxides, alloys
