WDS Energy Scans

  • Abstract

    In many samples, peak identifications in EDS spectra can be difficult to interpret, especially for energy peaks with competing elemental lines or with low amplitudes. Manual peak confirmation using WDS energy scans can be very useful to reduce the uncertainty of these locations. In addition, the increased motor speed of the Thermo Scientific MagnaRay permits wide energy range scans in a fraction of the time of conventional WDS spectrometers. These wide energy scans have many benefits, but can also lead to a few complications if the analyst is not aware of the consequences. This paper provides numerous examples of the benefits and potential pitfalls of energy scans with WDS.
