Electron Probe Micro Analysis and Backscatter Electron Imaging

 EPMA & BSE - Electron Probe Micro Analysis and Backscatter Electron Imaging

*We highly recommend a preliminary visual (photo) evaluation of a sample prior to submitting it for the more costly EPMA & BSE analysis. Many times we can identify common minerals and rock types, saving you hundreds of dollars in analysis fees. Please note, most samples are not recommended for EPMA analysis after the preliminary visual photo evaluation has been completed.

EPMA and BSE imaging services are provided by our partner Laboratory for Meteorite Classification and Analysis (LMAC). LMAC is a nonprofit laboratory dedicated to the analysis and classification of suspected meteorites. They use the JEOL JXA-8230 5 spectrometers located at the University of Colorado Boulder to perform energy dispersive spectroscopy (EDS) and wave dispersive spectroscopy (WDS) geochemical analysis of the sample. BSE imaging in tandem with EDS is used to establish the petrographic analysis and classification. LMAC Homepage.
