Electron Probe Microanalysis (EPMA)

As of 20-MAR-96 a digital CAMECA SX100 Electron Microprobe (introduced Sept'94) was being installed in Clausthal. The SX100 replaces an aging JEOL JXA-3 installed and operational since 1967, which was retired in May 1995 after 27 years of service. It is now on public view in the department as a museum piece.


A variety of standard materials that cover most geological and materials science applications is available. The original file format of analysis data is ASCII, but can be converted to Excel 5. Possible image formats are "Cameca" (ASCII), Sun Raster or TIFF. Only the Cameca format contains information about magnification and analysis conditions. Data transfer by floppy, CD-R, DAT tape or ftp.
