Electron Microprobe

EMPA at EPS

The electron microprobe facility at AMNH houses a 5-spectrometer Cameca SX-100 that was installed in July 1996. This probe can detect and analyze elements from B to U at concentrations as low as 0.01 weight percent. Stage movement has a resolution of 0.5 microns. The Bruker energy dispersive spectrometer system is fully integrated with the Cameca quantification software. The laboratory is managed by Adrian Fiege. The electron microprobe laboratory is a joint facility shared between the Museum and Columbia University's Lamont-Doherty Earth Observatory. The AMNH seeks to hire a PhD-level staff member to manage the facility upon Dr. Fiege's departure (please see careers page at AMNH).

The AMNH, City University of New York, and Columbia University have been awarded National Science Foundation funding to replace the SX-100 with an up-to-date instrument.
