Electron Ray Microprobe

The electron ray microprobe Cameca type SX100 is located at the Institut für Mineralogie und Kristallchemiein the downtown area of the university. It is used by the Schleid group to perform qualitative and semi-quantitative analyses.

All the Elements of the periodic table except hydrogen, lithium, beryllium and the noble gases can be detected with the help of electron ray micro analysis. The detectable elements of the second period (B, C, N, O, F) are very hard to distinguish though, since their characteristic spectra are situated in the same range und thus hard to resolve correctly. From the third period on the elements can be detected reliably and on suitable surfaces of the samples it is possible to perform a rather exact quantitative analysis.

In solid-state chemistry, the electron ray microprobe analysis is mainly used to verify the chemical composition of single crystals whose structure was solved by X-ray single crystal structure analysis.
