Other instrumentation in Geology and Geophysics

MC-ICP-MS: The GV Instruments IsoProbe installed at UW-Madison is a next-generation multi-collector inductively-coupled plasma mass spectrometer (MC-ICP-MS) that was installed in 2000. The IsoProbe is capable of very high-precision isotopic analysis and trace metal analysis of a variety of geologically important elements including Li, B, Mg, S, Cl, Ca, Cr, Fe, Ni, Cu, Zn, Se, Sr, Nd, Hf, Os, Hg, Pb, Th, and U.

Microprobe: A Cameca SX-50/51 electron microprobe that was installed in 1993 is capable in-situ chemical composition, X-ray maps from micro-scale areas, back-scattering imaging, and X-ray EDS analysis and mapping. The lab is managed by a full-time 100% university-supported research scientist, Dr. John Fournelle.

Ion probe: A new multicollector Cameca large radius ion microprobe (funded by NSF) was installed in the Department of Geology and Geophysics, UW-Madison in early 2005 as a national facility for stable isotope studies (WiscSIMS). The ion probe can also provide spatial-resolved trace element analysis. The lab is managed by a full-time research scientist, Dr. Noriko Kita.

Thin section shop: A ¾-time thin section preparatory, Brian Hess, maintains a complete facility in the department for variety of thin and polished sections.

Machine shop: A well-equipped shop is managed by a half-time machinist, Lee Putman, who has made components used in many designed instruments in the department.

Electronics shop: Located in the department, used primary for geological instrumentation, development and repair. It is staffed by full-time electronics engineers Lee Powell and Neal Lord.
