Shielded EPMA

Shielded Electron Probe MicroAnalyzer for Radioactive Samples

Derived from CAMECA state-of-the-art EPMA instruments, SKAPHIA can analyze almost all elements of the periodic table, revealing compositional information for both major and trace elements of radioactive sample. The information is obtained from sub-micron areas with ultimate precision and accuracy. It is designed to accept samples emitting b and g radiations with a maximum acceptable g radiation level of 111 GBq at an energy of 0.75 MeV.

Fully customized environment and analytical equipment

Column, spectrometers and sample stage are installed in a hot cell (lead or concrete shielded room).
Remote-manipulators and/or ball manipulators are used to insert and mount the radioactive samples.
The instrument is fully remote-controlled (stage, column, diaphragms...), with electronics and computer deported outside the “hot” cell environment.
All WDS analyzers and detectors are shielded to prevent the background caused by the g radiations.
The stage is made of Denal material.
The Secondary Elecron detector has a special orientation to avoid gamma ray perturbation.

A dedicated EPMA software program provides all necessary features for quantitative analysis, X ray mapping, line profile acquisition and data processing.
