The electron beam microanalysis (or Electron Probe Microanalysis ' EPMA ') with energy dispersive x-ray spectrometer (EDX) became a very much spread analysis method. It is an efficient microanalysis technology with minimum detectable substance quantities of less than 0,1 pico-gram. EPMA is used in all areas of the Nature Sciences, in Medicine, Technology, even in Forensic and everywhere, where Scanning Electron Microscopes are in operation.

The "micro analyst" has a very interesting working sphere. He or she goes into the world of microscopic dimensions. The micro world is opened...
