VWDSX is a sophisticated wavelength-dispersive electron microprobe analysis simulation software.

    A full set of pure standards spectra have been saved to a database. This allows Virtual WDS to display an hypothetic spectrum corresponding to a known composition sample.
  From this generated spectrum the user can then obtained very interesting information which relate to the analytical conditions which should be used when analyzing similar sample, i.e:

- Optimal background positions.

- Possible interferences.

- Peak to background ratio for a given accelerating voltage.

- Analytical precision and detection limits.

    The XMAS and Virtual WDS integration, allow those two software packages to communicate some information, elements and the compositions (XMAS à VWDS), the background offsets and the counting time (VWDS à XMAS).
