Overcoming energy peak overlap problems in EDS spectrum

in #steemstem4 years ago

Sometimes, due to certain elements having x-rays with energies that overlap, incorrect automatic determination of elements can occur during Energy Dispersive X-Ray Spectroscopy (EDS). This quick video gives a few examples of potential overlaps, how you can determine candidates in your own analysis and discusses how use of other higher energy peaks and wavelength-dispersive X-ray spectroscopy (WDS) techniques can help to confirm or discount the presence of elements in a given sample.
