Spectral mapping
WebSEM-EDS mapping combines the spatial resolution of modern electron microscope with the power of X-ray spectroscopy. By scanning an electron beam across the sample surface while actively collecting X-rays, high resolution elemental maps can be collected over an area of interest (Figure 1).
