Electron Microprobe

The electron microprobe is an ARL-SEMQ that was upgraded in 1994 with new motorization and software for 'fast' 6-spectrometer mineral and glass analyses.  I specialize in olivine, pyroxene, plagioclase, and oxide analyses, but the lab has mineral and glass standards to analyze about any phase in igneous and metamorphic rocks. A typical pyroxene analysis takes about 90 seconds; olivine and plagioclase can be fully analyzed in about one minute.  [Matrix corrections and automation package by John Donovan (Berkeley) and Advanced Microbeam (Vienna, OH)]
