KLM Markers

EPMA Xtreme Probe

KLM Markers

          - None:                            No KLM markers (default).

          - Acquired only:                 All KLM markers for all elements in the wavescan sample (acquired and specified).

          - All Elements:                   All KLM markers for all elements in range.

          - User Selected Lines:         Only lines selected by the user in the Load Xray Database window.

          - Specific Element     Only lines for the element selected in the list.

 

Note that the emission line wavelengths are read from the XLINE.DAT file which are self-consistent with the XEDGE.DAT x-ray edge energies for quantification, but may vary slightly from the values from the NIST KLM x-ray database. Note also that all KLM wavelengths are corrected for refractive index values before display (based on the analyzing crystal used for the acquisition), but all KLM lines are systematically shifted so the 1st order KLM lines coincide with the emission line wavelength from the XLINE.DAT file.

 

Note that one can configure Probe for EPMA to specify elements that should never show up in the KLM markers. The default forbidden elements are Tc, Pm, Po, At, Rn, Fr, Ra, and Ac. See the [Plot] section of the PROBEWIN.INI file for instructions on adding or deleting elements from this list. Note that x-ray lines do not exist for H and He so they are automatically excluded from the KLM database.
