Element distribution mapping

Besides punctual analyses, also the spatial distribution of elements an a sample can be visualised (along a line or for an area). The electron beam will either be scanned over the sample or the sample stage will be moved under a static beam. The X-ray intensities recorded by EDX and WDS systems are then used to display a map of the element concentrations. This is particularly useful for zoned minerals, in which the concentration gradients of certain elements can then be visualised.
