The degree of sophistication of computer-aided scanning electron microscopy/energy dispersive x-ray spectrometry (SEM/EDS) microanalysis has advanced to the point where it is possible with a single command to automatically perform sequential qualitative analysis (peak identification) and quantitative analysis and then create a report of analysis with full statistical support. Therefore, there are a number of peaks at these low energies and thus these peaks overlap, resulting in inaccurate elemental identification and quantification. “Paintings Fade Like Flowers”: Pigment Analysis and Digital Reconstruction of a Faded Pink Lake Pigment in Vincent van Gogh’s Therefore, the separation of some peaks can be poor. This will vary between different elements and analytical lines, and for the same element in different matrixes. Identification Attributes. EDS systems name A name given to this voice.

EDS can be used to determine which chemical elements are present in a sample, and can be used to estimate their relative abundance. These low beam energy microanalysis conditions force the analyst to use low fluorescence yield L‐shell and M‐shell peaks rather than higher yield K‐shell and L‐shell peaks typically selected for elements of intermediate and high atomic number under conventional high beam energy (>10 keV) conditions. However, the presence of overlapping peaks from different elements means that correct identification depends on being able to recognize the peaks in the different X-ray families. Working off-campus?
